It was Christmas Day, 1066. Westminster Abbey smelled of candle smoke and damp stone and the icy breath of winter coming through the great door. Outside, London waited in uneasy silence. The battle at Hastings had been in October, less than three months before, and the streets were still in shock, the city still trying to understand what had happened. Men who had been Englishmen when they woke up in September had found themselves, by November, living under foreign rule.

Inside the Abbey, the most powerful man in England was about to be crowned.

William, Duke of Normandy, knelt before the altar as Archbishop Ealdred of York placed the crown of England upon his head. It was the same crown that had sat on King Harold’s head in the same place barely a year before. The Norman knights standing in the abbey were armed, their hands on their sword hilts, their eyes scanning the crowd. They had fought their way here, and they were not yet sure the fight was over.

When the congregation were asked to shout their assent, their approval, to the coronation – in the Norman manner, the sound startled the Norman guards outside. They heard what sounded like a commotion inside the Abbey and panicked. Within minutes, the houses around Westminster were burning, and frightened Londoners were running into the streets. Inside the Abbey, the ceremony continued as smoke began to drift in, and the congregation scattered.

William was crowned King in a half-empty church, with his new capital city on fire outside. It was not the most promising beginning.

William was forty years old when he took England and became king, give or take a year, and he had been fighting for most of his life. He had survived a childhood in which three of his guardians were murdered in quick succession. He had fought off a rebellion when he was barely twenty, riding for his life through the night, and then turning to smash his enemies before they could regroup. He had conquered the county of Maine, on Normandy’s southern border, beaten back the King of France, invaded England with a borrowed army, and killed his rival King Harold. William was not a man who stopped to rest when there was still work to be done. And there was plenty of work to be done.

England in 1066 was not a kingdom that had simply switched rulers at the top and would now carry on as before. What the newly crowned King William had won was a country in shock, a country with powerful earls in every corner who had spent years fighting each other and were not necessarily willing to stop fighting just because a new Norman King had taken power. King Harold was defeated and dead, but England was still England. Its people still spoke English, its laws still Saxon laws, and its great landowners still powerful men with armed followers who had not been asked whether they wanted to be conquered and ruled by a foreign king.

King William’s first moves were careful ones. He kept some of the old Saxon earls in their positions, at least for a while. He kept the old Saxon laws in place, at least officially. He promised to govern as King Edward the Confessor had governed, and he wanted England to understand that this was not destruction but replacement, and that life would go on. Powerful Saxon men could remain powerful if they behaved themselves. It was a sensible plan, but it only lasted about three years.

The rebellions began in the west, in the north, and in the east. Some were led by Saxon earls who had submitted after the Battle of Hastings but could not stomach the reality of Norman overlordship. Some rebellions were stoked by the Danes, who were watching events in England with hungry interest, remembering the days when their own king had ruled the island. In 1069, a Danish fleet sent by King Sweyn of Denmark sailed into the north of England, and the whole of Northumbria erupted into open revolt.

It was the rebellion in the north that brought out the worst in King William, and the worst of what a conquest can become when a king decides that the only way to keep order is to make sure there is nothing left to support a rebellion.

King William marched north in the winter of 1069, into the coldest months, when no sensible army went to war. His men moved through Yorkshire in the snow, and wherever they went they burned. Not just settlements that had harboured rebels. All of them. The crops in the fields were set alight, though there was little left by winter. The livestock were slaughtered. The ploughs and tools were destroyed. The stores of grain that families had gathered to see them through the winter were tipped into the mud or taken. Village after village was left as a smear of ash on frozen ground.

It was thorough. It was deliberate. And it was terrible.

An early twelfth-century chronicler named Orderic Vitalis, himself half-Norman, wrote about it with horror. He recorded that King William’s campaign killed more than a hundred thousand men, women and children, most of them not through the sword, but through the famine that followed. Modern historians treat that figure as an exaggeration from a chronicler writing a generation after the event, but even so, there is agreement that the death toll ran into the tens of thousands, in a country whose entire population numbered no more than two million people. The Domesday Book, compiled sixteen years later, still recorded vast stretches of Yorkshire as wasteland, empty and untaxed, too sparse to count.

Even Orderic, who admired much of what King William had done, could not bring himself to defend the Harrying of the North – as it came to be called. He wrote that in his dying weeks, King William himself repented of it. Whether that is true, no one can say. But the fact that a loyal Norman writer felt the need to say it, tells you something about what the Harrying looked like to those who lived through it, and to those who came after. After the north was broken, there were no more rebellions.

England was now truly conquered, and King William set about remaking it from the ground up. The change began with the land.

In the old Saxon system, great earls had held their estates by tradition and inheritance, owing the king service and loyalty but otherwise ruling their own lands in their own way. King William swept almost all of that away. He distributed the land of England as he saw fit, and he saw fit to give most of it to other Normans.

Not just any Normans, his Normans. The men who had crossed the Channel with him, who had fought at Hastings in the October rain, who had marched north in the winter cold. These men were now rewarded with something more lasting than silver. They were given England itself, in pieces, to hold as their lord’s tenants in return for military service.

This was feudalism, (society structured around a strict hierarchy of land ownership and reciprocal obligations to the king) and King William understood it with a soldier’s clarity. The king was lord of all. Below him, the barons held their allotted portion of land, gifted to them by the king. In turn, the barons owed the king a fixed number of knights for when the king called for them. Below the barons, the knights held their own portions of the barons’ land and owed arms and men to the baron in turn. Below the knights, the peasants worked the land, and owed their labour and a portion of their harvest to whoever sat above them in the chain.

It was a pyramid, and William sat at the top of it.

By the time his survey was completed, (the Domesday Book) the land of England looked like this: where two thousand Saxon thanes and landowners had held estates in 1066, around two hundred Norman barons held all the estates by 1086. The old Saxon aristocracy had not merely lost power. It had almost ceased to exist.

The new Norman lords started to build in stone right across England. Castles went up, first in wood on earthen mounds, then in stone, as time and money allowed. They were not houses. They were statements of power, and amongst England’s first stone castles since the Romans. Every Norman castle said the same thing to the population around it: we, the Normans, are here. We are the new masters of England, and we are not leaving. By the end of King William’s reign, more than eighty castles had been built across his new kingdom, each one the centre of a lord’s authority, each one a garrison from which the surrounding land could be controlled. The villages that lay in the shadow of those castles did not easily become rebellious again.

Norman French was the language of power now. It was spoken at the royal court, in the law courts, and in the great Norman households. English went on being spoken, of course, in the fields and the markets and the homes of ordinary people, because you cannot conquer a language any more than you can conquer the weather. But the English who wanted to rise in the new order would have to learn French, and over the next two centuries the two languages pressed against each other and mingled, until the language that came out on the other side, was something new and strange and rather wonderful, full of Old English bluntness and Norman elegance, of Saxon words for the animals in the field and French words for the meat on the plate. The modern English we speak today carries both of those languages inside it.

The Church changed too. King William brought in Norman bishops and abbots to replace the English ones, slowly but deliberately. He was a religious man in the practical Norman way, building churches and abbeys, observing the forms. He was a king who understood that the Pope and the Church was a power he needed to keep on his side.

In 1085, a threat from Denmark reminded King William that England was only as secure as he kept it. King Canute IV of Denmark was raising a fleet and an army with the intention of pressing an old claim to the English throne. But King Canute IV never sailed. He was murdered by his own men, who were less enthusiastic about the venture than he was. But the threat from across the sea had been real, and it reminded King William of something he already knew: that he could not defend his kingdom if he did not know what it contained.

In December of 1085, King William called a great council at Gloucester and gave an order that had never been given before in the history of England. He wanted to know everything.

Not just which lord held which estate. Everything. A complete survey of the entire kingdom. Every farmer, every mill, every fishpond. Every ox, every cow, every pig. Who had held it before the Conquest, and who held it now. What it had been worth in King Edward the Confessor’s day, what it was worth when the surveyors arrived, and what it might be worth if it were properly managed. The Anglo-Saxon Chronicle recorded the scope of the thing with barely disguised indignation, noting that King William’s surveyors left nothing out, not a single yard of land, ox, cow, nor pig.

Commissioners — the surveyors — rode out across England early in 1086, divided into circuits, each circuit covering a region. They called the local people before them, the barons and the priests and the village reeves, and questioned them under oath. The information flowed back to Winchester, where clerks compiled it into a vast written record.

They called it the king’s survey. The people of England, knowing that it was final and beyond appeal, called it the Domesday Book. Doomsday, the day of judgement, when everything is known and nothing can be hidden. The name has lasted.

The Domesday Book was finished in 1086, all of it compiled in a single year. It remains one of the most extraordinary feats of medieval administration ever attempted. The book records over thirteen thousand places across England, though it left out some significant gaps: London and Winchester were not included, probably due to their size and complexity, and the far north, still raw from the Harrying, barely appears. But for everything else, it is there, every field and mill and villager, a frozen snapshot of a single year, but King William did not live to make much use of it.

In the summer of 1087, King William was campaigning in France, in the border region between Normandy and the French royal lands, and he attacked the town of Mantes in the Seine valley. The town burned, and as he rode through the smouldering ruins, his horse stumbled over debris in the ashes and lurched forward, throwing King William hard against the pommel of his saddle, hurting him internally. Injured and unable to continue, King William was carried to the priory of Saint Gervase outside Rouen and put to bed, and there he stayed, growing more ill through August and into September.

King William died on the ninth of September, 1087, aged about fifty-nine, having reigned in England for twenty-one years.

His end was not dignified. The men who had attended him at his deathbed, servants and courtiers alike, left the moment he died, stripping the room and taking everything they could carry. King William’s body had to be carried to Caen for burial at the abbey he had built there, and the ceremony went wrong. The grave was too small for a man who had grown very big and heavy in his later years, and those present had to press the body down into it. The smell of the king’s decaying body on that warm September day was never forgotten.

History judges William the Conqueror as a great and terrible man in the same breath. When he became King, William found England to be a country of competing powers. On his death, England was a unified feudal kingdom under a single crown. King William brought architecture, administration, and a new language. He also brought devastation, dispossession, and the Harrying of the North.

The Domesday Book is his most famous legacy. The original two volumes of the book still exist, and its home is the National Archives in Kew. The entries for English towns or villages, if they existed in 1086, can still be read in the original Latin today.

King Edward the Confessor was buried on the morning of the sixth of January, 1066, in the great church at Westminster, that he had spent the last years of his life building. Before the congregation had left the abbey, Harold Godwinson, the son of the great Earl Godwin and for thirteen years the real power behind King Edward’s throne, was crowned king. It was the fastest succession in English history.

King Edward’s body was barely cold, and Harold’s supporters had moved with a speed that suggests they had been planning for this moment very carefully. They had good reason to hurry. Somewhere across the Channel, the Duke of Normandy believed the English throne had been promised to him. And far to the north, beyond the grey waters of the North Sea, the King of Norway was already building ships.

Harold was not of royal blood but the Witan, the council of great men, accepted him. London cheered, and the Archbishop of York placed the crown upon his head. But Harold had become king at a particularly dangerous time.

Two men wanted the English crown for themselves, and they were both dangerous.

The first was William, Duke of Normandy. William was the bastard son of Duke Robert and a tanner’s daughter, and he had clawed his way through a childhood of murder, conspiracy, and civil war to become the most feared ruler in northern France. He claimed that Harold had sworn a sacred oath to support William’s right to the English throne. Whether Harold had sworn freely or under the kind of pressure is not known, but the oath existed, and in the feudal world, an oath was everything.

The second man was Harald Hardrada, the King of Norway. King Hardrada stood nearly seven feet tall and had spent his youth fighting as a mercenary in the imperial bodyguard at Constantinople. He was the most experienced warrior in Europe. His claim to England was old and thin, and rested on ancient agreements between the English and the Danish kings, but King Hardrada was not a man who spent much time worrying about the strength of his legal position. He had a fleet, he had an army, and he meant to use them.

King Harold knew they were both coming, but he did not know when, or who would come first.

Then, in the spring of 1066, a strange light appeared in the sky. It was a great star trailing a blazing tail, and it hung over England for weeks, bright enough to see at dusk. People stared up at it from fields and doorways and the dark lanes of market towns, and they were afraid. Lights in the sky meant something. The monks said it was a warning from God. But a warning for whom?

We know now that it was Halley’s Comet, following its long, slow orbit of the sun, as it had done many times before and would do so again. But nobody in 1066 knew that. They saw a blade of light in the sky, and they waited for whatever was coming.

All through the summer, King Harold waited with them.

He stationed himself on the south coast with his huscarls, his household troops, watching the sea for William’s fleet. The fyrd, the militia army, had been called out across the whole of southern England, and thousands of men stood ready along the Channel shore, watching the horizon, sleeping rough and eating whatever the local people could spare.

But the wind blew steadily from the north, and William’s ships could not cross the Channel. Week after week, the English waited. As the summer wore on, the men of the fyrd started to worry about their crops. They had fields and farms to harvest, but could not leave their posts.

Then, on the eighth of September, with no sign of an invasion, King Harold disbanded the fyrd and sent the men home to take in the harvest.

It was exactly the wrong moment.

A few days later, whilst King Harold was watching the empty English Channel, three hundred ships appeared off the coast of northern England. King Harald Hardrada had sailed from Norway, gathering warriors from Orkney, from the Scottish isles, and from the Isle of Man, and at his side was a man King Harold knew well. Tostig, Harold’s own brother, and driven out of his earldom of Northumbria the previous year. He had gone to the King of Norway with a grudge and a plan.

The Norwegian fleet sailed up the Humber and into the River Ouse, landing at Riccall, about ten miles south of the city of York. The northern earls, Edwin and Morcar, gathered what forces they could and marched out to meet the invaders.

On the twentieth of September, the two armies clashed at Gate Fulford, on the flat, marshy ground south of the city. The English fought bravely. Edwin and Morcar had brought a considerable force, and for a time they held their ground. But King Hardrada was an experienced commander with a larger army, and the English were pushed back into the marshes and the flooded ditches. The defeat was total. The northern earls escaped, but their army was destroyed.

The city of York was now open and undefended, so it submitted. In response, King Hardrada did not sack the city, but he demanded hostages and supplies, and he arranged to receive them at a place called Stamford Bridge, about eight miles to the east, where the old Roman road crossed the River Derwent.

King Hardrada and his army settled down to wait. The weather was fine. They had won their battle, taken the city, and the countryside was quiet. Many of the men left their armour on the ships at Riccall and lounged in the September sunshine in tunics and shirtsleeves.

They did not know that King Harold was already coming.

The news of the invasion had reached the king in London. Without hesitation, King Harold gathered his huscarls, his bodyguard, and rode north. The distance from London to York is nearly two hundred miles, and King Harold covered it in four days, calling out the local militia as he passed through each shire, and gathering men on the move. It was a punishing march. The men slept in their saddles, ate what they could find, and did not stop.

On the twenty-fifth of September, King Harold reached York. The city gates opened. He did not pause. He marched straight through and out the eastern side, heading for Stamford Bridge.

King Hardrada and his army saw the dust before they saw King Harold’s army, a great cloud rising on the road to the west, and beneath it, the glint of iron and the movement of thousands of men coming fast. The surprise was absolute.

What happened next is one of the famous stories of English history, though nobody can say with certainty how much of it is true. According to the Anglo-Saxon Chronicle, a single Norwegian warrior planted himself on the narrow wooden bridge over the Derwent and held it alone against the entire English army. He was a huge man, wielding a great axe, and he cut down every man who came at him. Behind him, on the far bank, his comrades scrambled to form their battle lines.

The lone warrior held the bridge until an Englishman floated beneath it in some kind of half-barrel or tub. Through the gaps in the planking, he thrust his spear upwards. The great Viking fell, and the English surged across.

The battle was savage. King Hardrada had been caught entirely off guard, but his men were experienced fighters, and even without their armour they formed their shield wall and held. The fighting raged around a great banner called Land-Ravager. Ultimately though, King Hardrada was struck in the throat by an arrow, and he went down.

Tostig took command. King Harold, in a gesture that tells you something about the kind of man he was, sent his brother an offer of peace and a full pardon, along with restoration of his earldom. He also offered to spare every Norseman still standing.

The offer was refused. The Norsemen shouted back that they would rather fall, one across the other, than accept mercy from the English.

So the fighting went on. A force of Norwegians who had been left with the ships at Riccall arrived at a run, carrying their mail coats. Some threw their armour aside and charged into the fight as they were. Nearly all of them were killed.

When the battle ended, the field was thick with the dead, and King Hardrada lay in the English earth he had come to conquer. Tostig lay dead beside him. Of the three hundred ships that had carried the Norwegian army to England, only twenty-four were needed to carry the survivors home.

King Harold buried King Hardrada with honour and allowed his son Olaf to depart in peace. King Harold had won one of the great victories of the age, and the Battle of Stamford Bridge ended the Viking threat to England forever. Never again would a Scandinavian army seriously threaten the English crown.

But King Harold had no time to rest.

On the twenty-eighth of September, just three days after victory, messengers arrived from the south. The wind had changed and William the Bastard’s fleet had crossed the Channel from St Valery, at the mouth of the Somme, and landed at Pevensey, a place to the northeast of the present-day town of Eastbourne.

Nobles and landless knights from all over northern France, from Brittany, Flanders, and even from southern Italy, had invested in William’s invasion. Their investment was in the ships and armed men, and they expected a share of English land if William succeeded.

William’s army was perhaps seven thousand strong. Among them were several thousand mounted knights, the finest heavy cavalry in Europe, and the horses were carried across the Channel in specially built ships. William and his army landed without opposition. The local fyrd, called out four times already that year to watch the coast, and having decided that the danger was past because it had not yet arrived, had gone home.

As William stepped from his boat he stumbled and fell flat on his face. The watching soldiers saw a bad omen. William, thinking fast, held up fistfuls of sand. ‘See,’ he said. ‘I have taken England with both my hands.’

William then went on to build defences around his fleet and loot and raid for food from across the Sussex countryside. He then waited.

King Harold and his huscarls, battered and diminished by the fighting at Stamford Bridge, rode south. They covered two hundred miles in about seven days, arriving in London in the first week of October. King Harold stayed in London for five days, gathering every man he could. The thanes and militia of Wessex and Kent came, but the northern earls, Edwin and Morcar, whose army had been broken at Gate Fulford, were far behind and moving south at their own pace. Whether they would arrive in time, or would fight for King Harold at all, no one knew.

On the evening of the thirteenth of October 1066, Harold marched south from London and took up his position on a ridge of high ground about seven miles from the town of Hastings, and blocking the road to London. The hill had no name then. It would later come to be called Battle.

The ridge was a strong position. The English army formed their shield wall along the crest, packed shoulder to shoulder, their round shields overlapping, their long axes and heavy swords ready. Harold’s personal banner, the Fighting Man, flew at the centre of the line.

They had no cavalry. They had almost no archers. What they had was the shield wall, the high ground, and the courage of men who had already marched the length of England and beaten one of the finest armies in Europe.

At dawn on the fourteenth of October, William’s army came up from the south.

The battle opened with a strange piece of theatre. A Norman knight named Ivo Taillefer rode forward alone, tossing his sword and lance into the air and catching them, singing as he came. He charged into the English lines, and was killed at once.

Then the battle commenced.

Wave after wave of Norman cavalry charged uphill at the English shield wall, their heavy horses labouring on the steep ground, lances splintering against the packed wall of wood and iron. King Harold and his army held on. Between the cavalry charges, Norman archers poured volley after volley of arrows into the English ranks. The toll was dreadful, but the shield wall held.

The axemen cut down the horses and riders with blows that could split a man from shoulder to waist, and the Norman knights had never faced infantry like this. They could not break through. They could not pull the wall apart. They fell back, reformed, and charged again, and each time the English held.

On the Norman left, the cavalry broke and fled back down the slope in disorder. The men on King Harold’s right, many of them local fyrd rather than professional soldiers, saw the enemy running and charged after them. It was a fatal mistake. William, in the centre, wheeled his disciplined troops onto the pursuers and destroyed them.

The hours and the battle, ground on. The English line grew thinner but did not yield. The dead and wounded lay so close together on the hilltop that the fallen could not sink to the ground.

Late in the afternoon, William tried the trick that would decide everything. He had seen how readily the English right had broken ranks in pursuit. Now he ordered a deliberate feigned retreat, sending his cavalry tumbling back down the hill in apparent panic. Again, the less disciplined English troops abandoned their positions and pursued them. Again, William’s army turned on them mercilessly and cut them down.

What remained was only the heart of King Harold’s army, the huscarls, the men who had fought at Stamford Bridge and marched south without rest. They gathered around their king and his banner, and they fought on.

William ordered his archers to shoot high, so that the arrows would fall in a steep arc over the shield wall. It in amongst this storm of arrows, that King Harold was struck.

How exactly King Harold died is not entirely certain. The traditional account says an arrow struck him in the eye. The Bayeux Tapestry, stitched within living memory of the battle, appears to show this moment, although scholars have argued for centuries about which figure in the scene is King Harold and what exactly is being depicted. What we know for certain is that Harold Godwinson, King of England, fell at the foot of his standard on that October afternoon 1066.

His brothers Gyrth and Leofwine had already been killed. The surviving huscarls withdrew into the woods behind the ridge, still fighting. William’s cavalry, pursuing in the fading light, rode into a deep, hidden ditch on the reverse slope. Horses and riders tumbled in, and the English who were still alive, fell on them in the darkness, but the battle was over.

William had three horses killed under him that day. He had fought in the front ranks, and had earned his victory in iron and blood. England was his.

King Harold’s body was found among the fallen, stripped of its armour. His mother offered to pay the weight of the body in gold for the right to bury her son in consecrated ground, but William refused. King Harold, he said, should be laid upon the shore he had given his life to defend. The body was later moved to Waltham Abbey, which King Harold himself had founded. It lies there still, somewhere beneath the quiet ground, although nobody now knows exactly where.

The hill at Battle is quiet today. The abbey that William built on the spot where King Harold fell, in penance, or in triumph, or perhaps something in between the two, is mostly ruins. But the ridge is still there, and the slope where the Norman cavalry charged is still steep enough to make you catch your breath if you climb it.

If you walk across that hilltop on an October morning, when the mist sits in the hollows and the rooks wheel overhead, you can feel the shape of the ground beneath your feet, the long crest where the shield wall stood, the falling ground where the cavalry struggled uphill. The grass has grown over everything, and the bones are deep in the Sussex clay.

King Harold Godwinson won two of the three great battles that were fought in the year 1066. He marched the length of England twice, defeated one of the greatest warriors in Europe, and turned to face another without pause. But he lost on an autumn afternoon, on a hill with no name, and when he fell, the Saxon world fell with him.

The Palace of Westminster stood on a low marshy island at the bend of the Thames, a few miles upstream from the city of London. In the first days of January 1066 in a room in the new palace, it was very quiet. Candles burned low, and around a bed in this room stood the men who had run England for the last twenty years: earls, thanes – nobles, and churchmen. They had come to hear the last words of King Edward the Confessor, the last of the old Saxon kings.

King Edward was old, grey, and very frail. He had been sick for some time, drifting in and out of wakefulness, and in his fever he had spoken of things that frightened the men who listened. He had spoken of a time of evil that was coming upon the land. He had described green trees cut down and replanted, but bearing no fruit. The words made no obvious sense, but they landed on the listeners like the tolling of a bell. On his deathbed, the king seemed less like a man and more like a prophet, muttering warnings that no one could fully understand and no one dared to ignore.

Only one man in the room remained unmoved. Archbishop Stigand was a survivor, a churchman who had served three kings and knew a political performance when he saw one. He leaned across to the Earl of Wessex and whispered in his ear. ‘The king was old and sick. Age had robbed him of his wits. His words meant nothing.’

The Earl of Wessex listened, and nodded. His name was Harold.

On the fifth of January, 1066, King Edward of England died. He had been king for twenty-four years.

His title ‘The Confessor,’ had been given by the Church because the man had spent his life in devotion and piety. And King Edward the Confessor had been genuinely, deeply, almost entirely concerned with God. In a time when England needed a warrior, it had been given a monk.

To understand why Edward came to sit on the English throne at all, we need to step back from that candlelit room and follow a stranger story.

When the great Danish king Cnut died in 1035, the empire he had built – England, Denmark, Norway – crumbled almost at once. He left three sons, and they were nothing like their father. They were boorish, cruel, and short-lived. Within seven years of Cnut’s death, all three were gone. One died fighting in Norway, one was dead within a year of taking the English throne, and the last, Hardicanute, who was Cnut’s chosen heir for England, died suddenly in 1042 at a drinking feast in Lambeth, collapsing in the middle of a toast. He was in his mid-twenties. There was no warning. He just dropped dead.

England had a problem. Who was the king?

The answer, when it came, surprised everyone. There was still a man alive who could claim descent from King Alfred the Great and the ancient West Saxon line. He had been living in exile in Normandy, across the Channel, for nearly thirty years. He had grown up there, had been educated in Norman monasteries, spoke French as naturally as he spoke English, and had spent so long away from his homeland that he was more Norman than Saxon in almost every way that mattered.

His name was Edward, son of King Ethelred the Unready and his Norman wife Queen Emma.

Bringing Edward back to England was the idea of the most powerful man in England at the time, Earl Godwin of Wessex. Godwin was not royal. He was a nobleman, not a king, the son of a thane who had risen through his own ability and shrewdness to become the greatest earl in the kingdom. He had served Cnut loyally, taken a Danish wife, and accumulated land and power until the territory he controlled stretched from the Thames in the east to the Bristol Channel in the west. He had sons who were already earls. He was, in everything but name, the ruler of England.

Godwin could have chosen almost any candidate for the throne, but he chose Edward because Edward could be managed. A king who had been away for thirty years, who had no army and no English allies, who owed his throne entirely to Godwin’s support – was a king who could be kept in check.

Godwin’s terms were simple. Edward could be king, but he must marry Godwin’s daughter, Edith. Also, he must keep Godwin and his sons in their earldoms. And he must remember who had put him there.

Edward had little choice. He agreed, was welcomed home, and was crowned King of England in Winchester on Easter Day, 1043.

Edward was about thirty-seven years old when he became king. He was slight, pale and quiet, a man who had spent his youth in Norman monasteries rather than riding to war. One account of the time describes him as a kindly, gentle, chubby figure, with an almost otherworldly appearance. His Norman education had given him a genuine and deep religious faith, an appreciation of Norman architecture and Norman learning, and absolutely no experience of governing a kingdom.

He married Godwin’s daughter Edith as agreed. The marriage was, by all accounts, entirely formal. Edward seems to have regarded it as a duty rather than a union. This was not unusual for a man of Edward’s piety. He treated his queen respectfully enough, but his heart was elsewhere – in his prayers, in his devotions, and above all in the great project that would be his life’s real work.

He was going to build a church.

The church – or rather, the abbey – was to be at Westminster, on the marshy island where the Thames bent south. There had been a modest monastery there for some years, but Edward intended something altogether different. He wanted a building in the new Norman style, with great round arches and thick stone walls and a soaring nave that would fill the eye and lift the spirit. He poured money, energy, and attention into it for the rest of his life. Westminster Abbey was consecrated just days before Edward died, but he was too ill to attend the ceremony for a building that he had spent his entire reign building.

That was the man. Quiet, devoted, happiest among his monks and his mason’s drawings, increasingly withdrawn from the rough, treacherous world of earls and councils. He was not stupid. He was not entirely without cunning, but he was profoundly unsuited to the time and the place in which he found himself, and he knew it.

Meanwhile, England was being run by Godwin.

Earl Godwin of Wessex was one of the most able men of his age, and one of the most dangerous. He had helped raise Edward to the throne, and he intended to keep his hand on its back. His sons were given earldoms. One son, Sweyn, received Herefordshire and part of the west. Another son, Harold – the same Harold who would one day stand at Edward’s deathbed – became Earl of East Anglia. A third, Tostig, was given the north. The Godwin family, between them, controlled most of England, with a puppet king sitting quietly in the palace at Westminster, commissioning his stone carvings and praying his prayers.

Not everyone was content with this arrangement.

The Normans, who had sheltered Edward during his long exile, had followed him to England in considerable numbers. Norman priests appeared in the English Church. Norman clerks came to work in the royal household. Norman landowners began to acquire English estates. To the old Anglo-Danish nobility, this was an invasion of a different kind, creeping in through the doors of the king’s favour rather than storming up the beaches.

The arrangement between the two worlds – the Norman party around the king, and the great English earls, Godwin and his sons at their head – could not last forever.

The agreement broke in 1051.

A Norman archbishop, Robert of Jumièges, had been appointed to Canterbury, the most important position in the English Church. Godwin objected. A dispute broke out over the town of Dover, where local men had brawled with some of the king’s Norman guests. The king ordered Godwin to punish the town. Godwin refused. Suddenly what had been a long-running quarrel became an open crisis.

The earls gathered their forces. So did the king. For a few weeks England teetered on the edge of civil war. But Godwin, calculating that the odds were not in his favour, chose to withdraw. He and his sons crossed the Channel to Flanders, a region on the northern coast of what is now Belgium, and for the first time in twenty years the most powerful family in England was gone.

It was the moment King Edward had been waiting for. Norman influence flooded in. Robert of Jumièges remained as Archbishop. The Norman party strengthened its grip. And according to some accounts – though this is where history becomes uncertain, and the mists thicken – William, the Duke of Normandy, visited England around this time, received as an honoured guest at King Edward’s court.

William was a remarkable figure. His father, Duke Robert of Normandy, had spotted a tanner’s daughter washing linen in a stream near the town of Falaise and had fallen instantly in love with her, carrying her to his castle and keeping her there until she gave him a son. William was that son, born without the blessing of marriage, carrying the mark of illegitimacy that his enemies would never let him forget. His childhood had been dangerous: his father died when William was seven, leaving the boy a duke in name only, surrounded by great noblemen who saw a fatherless child as an opportunity rather than a ruler. Three of his guardians were murdered. For years his survival depended on luck, speed, and the occasional intervention of the King of France, who preferred a weak Norman duke to a strong one.

But William survived, and more than survived. By the time he came to King Edward’s court, in his mid-twenties, he was already proving himself a formidable soldier and ruler. William had broken his enemies, secured his borders, and looked across the Channel at England with the clear, calculating eyes of a man who was accustomed to taking what he wanted to and holding it.

What William wanted, it appears, was the English crown.

The story that King Edward promised the crown to William during that visit is Norman in origin, and the Normans had excellent reasons to tell it. King Edward had no children, no clear heir, and a king who had no children had to think about who would rule after him. William was his cousin, of a sort – the connection ran through KIng Edward’s Norman mother Emma and the family of the Norman dukes. And Edward trusted Normans. He had grown up among them.

Whether the promise was made or not, the matter was not yet settled. Because twelve months later, the Godwins came back from Flanders.

Earl Godwin had not wasted his year in Flanders. He had raised a fleet, called in favours, and gathered allies. His son Harold had done the same, raising ships in Ireland. In the autumn of 1052 they sailed for England from opposite directions, gathered their forces, and confronted King Edward with an army at their backs.

Edward looked at what was ranged against him, and did what a wise man does when he cannot win. He negotiated.

Godwin and his sons were restored to their earldoms. Most of the principal Norman agents were expelled. The Norman archbishop Robert of Jumièges fled the country. The king was back in his palace, back to his building works and his prayers, but the world around him had rearranged itself, and the Godwin family were stronger than before.

Seven months later, Earl Godwin was dead.

He died in 1053, at the king’s table during a feast at Winchester, suddenly stricken, carried from the hall, and dead within a few days. He had been in public life for over thirty-five years, and he died as he had lived: at the centre of power. His eldest surviving son Harold stepped into his earldom, his lands, and his authority.

Harold Godwinson, now Earl of Wessex, was about thirty years old. He was tall, strong, experienced, popular with the English nobility, and, in the view of almost everyone who dealt with him, extremely capable. For the next thirteen years, while the king prayed and planned his church, Harold governed England in his name.

Earl Harold was not always without opposition. His brother Tostig, Earl of Northumbria, resented his power. The Anglo-Danish earls of the north – Morcar and Edwin – were rivals, and the Normans never disappeared entirely from court. Harold navigated all of this with patience and skill, and the country held together. England, under Harold’s hand, functioned.

But under the surface, the questions were growing. King Edward was ageing and unwell. He had no children, no declared successor, no settled plan for the future. And across the Channel, William of Normandy had not forgotten whatever had passed between him and the king in 1051.

In 1064, Harold made a mistake. The exact reason for his journey across the Channel is not known. He may have been on a diplomatic mission. He may have been trying to secure the release of hostages. Whatever the reason, his ship was blown off course by a storm and he was wrecked on the coast of northern France, in the territory of the Count of Ponthieu.

The Count was not sympathetic. A shipwrecked man was, by the custom of the time, the property of whoever found him, and valuable for ransom. Harold found himself a prisoner, and his chances of ever leaving France grew uncertain.

It was William of Normandy who secured his release. He sent word to the Count – politely at first, then with rather more authority – that the Earl of Wessex should be delivered into Norman hands. The Count complied. Harold was escorted to William’s court.

What followed was both a friendship and a trap.

The two men liked each other. They are described hunting together, campaigning together against the Bretons, riding side by side with hawks on their wrists. Harold was honoured, feasted, and knighted by William. But William had not rescued Harold from the Count of Ponthieu out of generosity. He had rescued him because Harold was the most important man in England, and William had a use for him.

William put his proposal plainly. When Edward died – and King Edward, clearly ailing, would not live much longer – William intended to claim the English throne. He was offering Harold a share of the arrangement. Harold would become Earl of all Wessex, holding it under William as king. Harold would marry William’s daughter. William would be England’s king.

Harold swore an oath to this agreement.

The exact circumstances of that oath have been argued about ever since. Norman accounts say Harold swore willingly and knowingly on holy relics, giving the oath the most solemn weight it was possible for any promise to carry. English accounts say the terms were forced upon Harold, and that he swore under duress, with no real freedom to refuse. The relics, according to some later writers, were concealed beneath the altar, hidden from Harold until after the oath was taken, and Harold not fulling understanding what he was agreeing to.

What is certain is that Harold swore the oath, and that he went home. And equally certain is that in the autumn of 1065, the north of England rose in revolt against his brother Tostig. The Northumbrians had had enough of Tostig’s harsh rule and drove him out, calling for Morcar in his place. Harold, faced with the choice between his brother and a peace settlement, chose the settlement. Tostig was stripped of his earldom and sent into exile.

Tostig never forgave Harold. He sailed for Flanders, and there, burning with fury, began to look for allies who might help him take back what he had lost.

In December 1065, King Edward was too ill to attend the consecration of his beloved abbey at Westminster. He had spent the last years of his reign watching its stone walls rise, planning every arch and column, pouring the kingdom’s treasure into the building. Now it was complete, but he was very ill and took to his bed in the palace next door and did not rise from it.

In the first days of January 1066, the men of the kingdom gathered around him. They heard his confused, drifting words about green trees and blighted harvests, about a time of evil coming upon the land. The candles burned low. Beside the bed, Archbishop Stigand leaned towards Harold and whispered that the king had lost his mind.

But it was said that with his dying breath, Edward turned to Harold, the vigorous, competent man who had governed England in his name for thirteen years, and commended him to the kingdom’s care.

On the fifth of January, 1066, King Edward the Confessor died.

Within hours, Harold was made king.

It was the beginning of the most extraordinary year in the long history of England. The year of Halley’s Comet, blazing across the sky like a warning written in fire. The year of three battles – at Gate Fulford, at Stamford Bridge, and at a hill in Sussex that would change everything. Across the Channel, a Norman duke was sharpening his sword. Far to the north, in Flanders and beyond, a bitter exile was plotting his revenge.

And in Westminster, the new king stood in the newly consecrated abbey and received the crown that a Norman duke across the Channel believed had been promised to him.

King Edward the Confessor is one of the most puzzling figures in English history, not because we cannot understand him, but because he does not quite fit any of the usual shapes. He was not a warrior, not a statesman, not a clever politician playing the long game. He was exactly what he appeared to be: a man of genuine faith, more comfortable in a monastery than a council chamber, who happened to be a king.

He left behind a building that still stands. Westminster Abbey, rebuilt and added to over the centuries, has been the site of every coronation since William the Conqueror was crowned there on Christmas Day 1066 – nine hundred and fifty years of kings and queens receiving their crowns in a church that King Edward built.

King Edward also left behind a crisis – no clear successor.

There was disputed promise to a Norman duke. There was an English earl who had just taken the crown with the whispered blessing of a dying king. There was Tostig, Harold’s embittered brother, seething in exile in Flanders and already looking for someone to help him take his revenge. And, although no one in England yet knew it, a Norwegian king named Harald Hardrada who believed the English throne was rightfully his, and was already making plans to come and take it.

The lights of Saxon England, as one historian memorably put it, were going out. In the gathering darkness, a gentle man had murmured his warnings, and no one had truly listened. And now, in the cold January of 1066, those who had been standing around the bed turned from the dead king to the living one, and wondered what was coming next.

They would not have to wait long.

The silver was weighed out at Southampton. Forty-eight thousand pounds of it, heaped on scales and counted and loaded into chests while Danish soldiers stood over the English and watched. It was the year 1012, and England was paying its enemies to go away. Again.

This was the Danegeld, the tribute that had become a national humiliation. King Ethelred had been paying it for twenty years, each time a larger sum, each time buying a shorter peace. Ten thousand pounds in 991. Sixteen thousand in 994. Twenty-four thousand in 1002. Thirty-six thousand in 1006. And now forty-eight thousand, wrung from a country that was already starving. To enforce the collection, the Danes had sacked Canterbury and seized its Archbishop, Alphege. When the old man refused to let his flock be squeezed for ransom, they killed him at Greenwich, pelting him with cattle bones at a drunken feast.

The money never worked. The Vikings took the silver, sailed home, spent it, and came back for more. They were not stupid. Why risk your life fighting for a kingdom when its king would hand you its wealth and ask only that you leave? And if you did leave, you could always return next year, when the barns had been refilled and the people had just enough left to be worth robbing again.

Everything that King Alfred had built – the fyrd, the burhs – army and fortified towns – the navy, the laws, the very idea of a united English kingdom – was crumbling. Not because the system had failed, but because the man at the top had failed the system. Ethelred, whose name meant ‘noble counsel’, was known to his own people as ‘the Unready’, which did not mean unprepared in the way we use the word today. It meant ‘poorly counselled’ – a king who took bad advice and followed it. The Anglo-Saxons, who loved a dark joke, noticed the irony. Noble counsel, the ill-counselled. Even his name mocked him.

Under King Ethelred, the English did not lack courage. At the Battle of Maldon in 991, the ealdorman of Essex, a powerful lord named Byrhtnoth, had faced the Viking army across the tidal causeway at the river Blackwater and refused to pay. He told them they would receive nothing but spears and swords. When the tide fell and the causeway was exposed, Byrhtnoth even allowed the Vikings to cross so that the battle could be fought fairly. It was magnificent, and it was foolish. The English lost, and Byrhtnoth was killed. A group of his thanes – his nobles – knowing that everything was finished, fought on around his body until every one of them was dead.

That was the spirit of the English people. But spirit alone could not save a kingdom whose king paid silver instead of drawing swords.

In 1002, King Ethelred did something far worse than paying tribute – panicked. Convinced that the Danish settlers living peacefully in England were plotting against him, he ordered a massacre. On the thirteenth of November, St Brice’s Day, his men turned on every Dane they could find in the south of England, and killed them. Among the dead was Gunnhild, the sister of Sweyn, King of Denmark.

Sweyn’s revenge was terrible. For years his armies burned their way across England, sacking Exeter, Wilton, Norwich, and Thetford. The English built a new fleet in 1009, a desperate effort by a broken and starving people, but its commanders quarrelled among themselves, some ships were lost in a storm, and the rest were abandoned. The Anglo-Saxon Chronicle recorded it with weary contempt: the naval commanders let the whole nation’s toil pass away.

By 1013, Sweyn returned with his youngest son, a prince named Canute. The Danes of Yorkshire and the Five Boroughs of the old Danelaw submitted at once. Oxford fell. Winchester fell. London held out for a time, but it made no difference. Sweyn was accepted as King of England, and King Ethelred fled across the Channel to Normandy, whose duke’s sister he had married.

It looked like the end. But King Sweyn died suddenly in February 1014, and the English turned back to their old king. They would have King Ethelred again, they said, if only he would rule them better than before.

He did not.

The last flicker of King Alfred’s blood burned on in King Ethelred’s son, a young man named Edmund. At twenty, he was already a warrior of startling ability. Though his own father declared him a rebel, Edmund gathered forces, struck hard at the Danes, won battles, and relieved London when it was besieged. The English called him Edmund Ironside, and for a brief, brilliant moment it seemed as though the house of Wessex might survive.

But in 1016, still not yet thirty, Edmund Ironside died. The cause of his death is uncertain. Some chronicles hint at murder. Whatever happened, the last defender of King Alfred’s line was gone, and England surrendered.

At Southampton, even before Edmund’s death, the chief men of England – bishops, earls, and thanes, both Saxon and Danish – had agreed to set aside King Ethelred’s family for ever and accept a new king. All resistance, moral and military, collapsed. The last sons of the house of Wessex fled into exile. The young Danish prince who received this surrender was still in his early twenties. His name was Canute.

What happened next is one of the most unexpected stories in the history of the British Isles. The English expected a conqueror. They expected the son of King Sweyn to rule them as a Viking war-lord, with axe and terror and tribute. They had seen nothing else from the Danes for forty years. The country lay exhausted, its silver bled away, its towns burned, its people starved and beaten. If Canute had been cruel, no one would have had the strength to stop him.

Instead, he did something astonishing. He chose to become English.

There were, as the chroniclers understood, three ways a man could become king. He could take the throne by conquest, and no one could argue with a drawn sword. He could inherit it by blood, if his family had held it before him. Or he could be chosen – elected by the great men of the realm, who agreed that he was the best man to rule. Canute did not rely on conquest alone, though he had the power to do so. He had himself recognised as king by the English leaders, bound himself by oath to rule justly, and began his reign not as a tyrant but as a man who intended to earn his crown.

The first thing King Canute did surprised everyone. He sent the great Danish army home. This was the force that had conquered England, the army whose soldiers expected land and plunder as their reward. King Canute paid them off with a final, enormous levy and then dismissed them. He kept only a small personal guard of household troops, and for the defence of his new kingdom he trusted not to Danish swords but to the loyalty of the English people he had just defeated.

It was an extraordinary gamble, and it worked.

He married Emma of Normandy, who had been King Ethelred’s queen. Emma was one of the most remarkable women of her age. She was the sister of the Duke of Normandy, and she had already lived through more than most queens would see in three lifetimes – married young to a failing king, driven into exile, widowed in a ruined country. Now she married the man who had conquered her first husband’s kingdom. It was a political masterstroke for King Canute, because with Emma as his queen, the Normans had no reason to interfere in England on behalf of King Ethelred’s exiled sons. But Queen Emma was no passive pawn. She understood English customs and English politics. She had lived in the country for years, she knew its people, and she would outlast King Canute himself, surviving into the reign of her own son and shaping events long after the Danish king was dust.

Then King Canute set about rebuilding everything King Ethelred had broken.

He ruled according to the law. Not Danish law imposed on a conquered people, but the old English law that had grown up over generations, the laws of King Edgar and King Alfred before him. He made it known that these laws were to stand above even the king’s own power. When he sat in judgement, he judged by the same rules as everyone else. He even submitted himself to the regulations of his own household troops, following the same discipline he expected of his men. For an eleventh-century king, and a conqueror at that, this was extraordinary. Most rulers made the law serve them. King Canute made himself serve the law.

Of all his kingdoms – and he had many – King Canute chose England as his home. He was already King of Denmark. He won the throne of Norway. Scotland offered him its submission. The old Viking power, though weakening, still stretched from Scandinavia through the Baltic to the coasts of North America. King Canute ruled an empire that reached across the known world. But it was in England that he chose to live, in English churches that he prayed, and in the English manner that he governed.

He wished, we are told, to be seen as the successor of King Edgar, whose peaceful reign still glowed in English memory like a lamp in a darkened room. King Edgar had been dead for forty years, but his name still meant order, justice, and prosperity. King Canute wanted to be that kind of king.

He built churches and gave lavishly to English monasteries. He honoured the memory of the English saints, including St Edmund and St Alphege – the very Archbishop whose murder at Greenwich had been one of the most shocking acts of the Danish wars. King Canute carried Alphege’s relics to Canterbury with great ceremony, honouring a man his own people had killed. It was an act of remarkable political skill, but it was more than politics. King Canute seemed genuinely moved by the faith he had adopted. Early records describe him entering monasteries with his eyes fixed on the ground, weeping freely, beating his breast, praying aloud that he might deserve God’s mercy. The English noticed. Whatever else this Danish king might be, he was not pretending.

In 1027, he travelled to Rome as a pilgrim. He attended the coronation of the Holy Roman Emperor, Conrad, and was treated as one of the great rulers of Christendom. From Rome he wrote a letter home to the people of England, promising to rule with justice and to protect the Church. The letter survives, and it reads like the words of a man who took his duties seriously. He wrote not as a foreign conqueror addressing his subjects, but as an English king speaking to his people.

Everyone knows the story of King Canute and the tide.

The king, so the tale goes, sat in his throne upon the seashore and commanded the waves to stop. The tide came in regardless, soaking his robes and his royal feet, and King Canute turned to his courtiers and said something they did not expect. He had not been trying to prove that he could control the sea. He had been proving the opposite – that he could not. The lesson was for his flatterers, the men who told him he was all-powerful and could do anything he wished.

No king, King Canute was telling them, is greater than the forces that govern the world. Only God commands the tide.

It is a good story, and it may even be true, though it was first written down by a chronicler named Henry of Huntingdon about a hundred years after King Canute’s death, so we cannot be certain. What matters is what the story tells us about how the English remembered their Danish king. They remembered him as a man who knew the limits of his own power, a king who was wise enough to be humble. In a century of arrogant fools and terrified weaklings, King Canute was something rare: a strong ruler who was not drunk on his own strength.

But King Canute was not a saint, and his court was not a peaceful place.

A story from the Norse sagas, written about two centuries after his death, gives a very different picture. One evening, so the saga tells us, King Canute was playing chess with his brother-in-law, Earl Ulf. The king made a bad move, and when Ulf captured one of his pieces, King Canute tried to take the move back. Ulf refused. King Canute insisted. Ulf, furious, knocked over the chessboard, stood up, and walked out.

‘Run away, Ulf the Fearful,’ the king called after him.

Ulf turned at the door. ‘You did not call me Ulf the Fearful at the river Helgeå,’ he said, ‘when the Swedes were beating you like a dog.’

Ulf went to bed. The next morning, King Canute sent a boy to kill him. The boy came back and said he could not do it because Ulf had gone to church. So King Canute sent a man called Ivar White, a Norwegian from his household, and Ivar went into the church, walked up to the choir, and ran his sword through Ulf where he stood.

When Ivar returned with the bloody sword, King Canute asked if the deed was done.

‘I have killed him,’ said Ivar.

‘You did well,’ said the king.

The monks closed the church and locked the doors. King Canute sent word that they should open them again and sing Mass. Then he gave the church a great gift of land, and those lands, the saga says, belonged to it ever after.

This is a saga, not a sworn account, and it was written long after the events it describes. But the story captures something true about the world King Canute inhabited. He was a Christian king who built churches and wept at the shrines of saints, and he was also a Viking war-lord who had men killed for defying him. He was both things at once, and neither cancelled the other out. The eleventh century did not ask its kings to choose.

What King Canute built, however, depended on King Canute. That was both the strength and the weakness of his reign. When the great man died in 1035, at Shaftesbury in Dorset, he was perhaps forty-five years old. And his empire died with him.

He left three sons. Two were by an earlier wife, Ælfgifu of Northampton: Harold, who was called Harefoot, and Sweyn, who was sent to rule Norway. The third was Hardicanute, his son by Queen Emma. None of them was fit to hold what their father had made.

Harold Harefoot seized England. Canute’s son Sweyn was driven out of Norway within two years. King Hardicanute, trapped in Denmark dealing with threats to his own throne, could not come to claim his English inheritance. The empire that had stretched from the North Sea to the edge of the known world fell apart in months.

In Normandy, two young princes watched and waited. They were Alfred and Edward, the sons of King Ethelred and Queen Emma, the last of the old West Saxon line. They had grown up in exile, guests at the Norman court, speaking French, learning Norman ways, remembering a country they had been forced to leave as children.

In 1036, the elder brother, Alfred, crossed the Channel. The chroniclers call him ‘the innocent prince’, and perhaps he was. He came, or so he said, to visit his mother. But England was a dangerous place for a son of King Ethelred. An earl named Godwin, the most powerful man in the country, had Alfred arrested. His companions were slaughtered. Alfred himself was blinded, and died soon afterwards in the monastery at Ely.

It was a crime that would echo through the next thirty years of English history. And it left only one surviving son of the old royal line: Edward, the younger brother, still waiting in Normandy, still watching.

Harold Harefoot died in 1040. King Hardicanute crossed from Denmark to claim the English throne at last, but he was a hard, joyless king who taxed the country savagely and achieved nothing of note. Two years later, at a wedding feast in Lambeth, King Hardicanute raised a drink and fell dead.

The sons of King Canute were finished. In seven years they had squandered everything their father had spent twenty years building.

And now the great men of England looked around for a king. The country was tired of Danish princes. The old West Saxon line, the line of the kings Alfred, Athelstan and Edgar, still carried a kind of magic in people’s minds, a sense of rightness that no amount of conquest could entirely destroy. Their eyes turned back across the Channel, to the last quiet prince of King Alfred’s blood. Edward, the son of King Ethelred and Queen Emma, came home to a country he barely knew and was crowned King of England. He would be remembered as King Edward the Confessor, and in the choices he made and the weakness he showed, he would set England on a path that led, thirteen years after his own death, to the most famous year in English history.

But that is another story.

King Canute’s body was buried at Winchester, in the Old Minster, the ancient church at the heart of the old West Saxon capital. His bones lay there for centuries, moved from place to place as churches were rebuilt and demolished and rebuilt again.

Today, in the medieval cathedral that replaced the Old Minster, there are six painted mortuary chests set high on the stone screens above the choir. They are old and battered, cracked by age and damaged by Parliamentarian soldiers who threw them to the floor during the Civil War, scattering the bones across the stone. The remains were gathered up and put back, but by then no one could tell which bones belonged to which king. Inside those chests, jumbled together by the carelessness of centuries and the violence of war, lie the remains of several Saxon and Danish kings. King Canute’s are said to be among them.

It is a strange ending for a man who held five kingdoms in his hand. But perhaps it is a fitting one. He came as a Dane and chose to become English. He was buried among English kings. And in the end, as the centuries passed and the bones were moved and muddled and forgotten, the conqueror became indistinguishable from the conquered. The bones of Denmark and the bones of Wessex lie together in the same quiet chests, in the same English cathedral, in the same ancient city where King Alfred himself once walked.

King Alfred died in 899, and the kingdom he left behind was the strongest it had ever been. The burhs – the fortified towns, guarded the coasts and river valleys. The fyrd – the army, could be called upon and kept where needed. The laws were written down, the schools were open, and the Anglo-Saxon Chronicle was being kept year by year in monastery after monastery, a running record of the life of a nation that had very nearly ceased to exist.

But south of the river Humber was not the whole of England. To the north and east, across the old boundary line that King Alfred and the Viking leader Guthrum had agreed, lay the Danelaw, where Viking settlers had put down roots, married into the local community, farmed the land, built their own towns, and kept their own customs and traditions. They were not the same raiders who had burned Lindisfarne and waded through blood at York. A generation had passed. Many of them were Christian now, but they were still Danish, still independent, and still a kingdom apart.

King Alfred’s son Edward, known to history as Edward the Elder, set about changing that.

Edward was not his father. He did not write books or translate Latin or sit up late worrying about the state of learning in England. He was a soldier, and a very good one. Where King Alfred had built the system, Edward used it. He advanced north and east, year by year, building new burhs as he went, each one a day’s march from the last, extending the chain of fortified towns that his father had begun until it covered not just Wessex but the whole of the English midlands.

And he did not do it alone. Beside him, and often ahead of him, was his sister.

Æthelflæd, the Lady of the Mercians, is one of the most remarkable figures in early English history, and one of the least remembered. She was King Alfred’s eldest daughter, married to Ethelred, the ealdorman (an official and local leader) of Mercia, and when Ethelred grew ill and could no longer lead, Æthelflæd took command. Not as regent, not as a temporary stand-in, but as ruler in her own right. The Mercians accepted her, followed her, and fought for her.

She built burhs of her own. She led armies. She captured Derby, storming the town in 917 and losing four of her most trusted thanes – her noblemen, in the fighting. The following year the town of Leicester surrendered to her without a battle. When an abbot under her protection was murdered in the Welsh kingdom of Brycheiniog, she invaded within three days, took the queen and thirty-four hostages, and forced the Welsh king to submit. She was negotiating with the Viking rulers of York when she died in June 918, at Tamworth, in the heart of Mercia. The Anglo-Saxon Chronicle records her death in a single line, without sentiment. But the Mercian Register, a separate record that someone cared enough to keep, tells us more. It tells us that the people of York had offered to place themselves under her protection. Had she lived a few months longer, a woman might have united early England.

Edward survived her. By the time he died in 924, the Danelaw south of the Humber had been reconquered. Every Danish settlement between the Thames and the Humber now recognised the authority of the English King Edward. It had taken a quarter of a century of patient, grinding work, burh by burh, town by town, and it was the direct continuation of everything King Alfred had planned.

King Edward’s son Athelstan went further still.

King Athelstan was the third of the great West Saxon warrior kings, and perhaps the most ambitious of them all. He marched into Yorkshire in 926, and the north submitted. The Kings of the Scots and of Strathclyde acknowledged him as their overlord. The Welsh princes agreed to pay tribute. For a brief, shining moment, one English king held authority over almost the whole island of Britain.

It did not last. In 937, every enemy Athelstan had beaten rose up at once. Constantine, the King of the Scots, was an old man by now, cunning and proud, who had ruled his kingdom in the north for more than thirty years, and he had no intention of bowing to an English overlord. He joined with Olaf, a Norse king who ruled Dublin and wanted to reclaim the Viking kingdom of York. Norwegian raiders joined them from across the sea, along with the remnants of the old Northumbrian resistance. Together they assembled the largest hostile force the English had faced since the Great Viking Army. They meant to break the power of Wessex for good.

King Athelstan met them at a place called Brunanburh.

No one knows for certain where Brunanburh was. Historians have argued about it for centuries, placing it in locations from the Wirral to Scotland, and no site has been proven beyond doubt. But the battle itself was remembered. A victory poem was composed and entered into the Anglo-Saxon Chronicle, and it is one of the oldest pieces of English war poetry that survives. It sings of shields hacked apart, of swords hammering at battle-shafts, of the field stained with blood. It sings of the sun passing over the slaughter like a bright candle, and of the aftermath, when the ravens and the wolves came to feed on the dead.

The English won and Constantine fled north. Olaf sailed back to Dublin with the shattered remains of his fleet. King Athelstan, King Alfred’s grandson, had become one of the most powerful rulers in Europe. He styled himself Rex totius Britanniae on his coins and charters, King of all Britain, and the courts of Europe believed him. His three sisters married into the royal houses of France and the Holy Roman Empire. No English king before him had stood so high.

He died just two years later, in 939. He was followed by his half-brother Edmund, who was only eighteen, and then by Edmund’s brother Edred. Both were fighters. Both held the kingdom together against fresh rebellions and fresh Viking incursions from the north. And both died young. But by 954, when the last independent Viking king of York was driven out and killed, the work was done. The whole of England, from the Channel to the Scottish border, was under a single English crown.

It had taken eighty years and five warrior kings, starting with King Alfred and ending with King Edred. They had beaten the invaders, reconquered the Danelaw, and built a nation, but the cost in blood and suffering was enormous. Hoewever, underneath all the fighting, something quieter and more important had happened. A country had been made. Not just conquered, but organised, administered, and given a shape that would last.

Under King Edgar, who came to the throne in 959, this long building reached its height.

King Edgar’s reign was peaceful, which is precisely why most history books skip over him. There were no great battles, no dramatic sieges, no narrow escapes. But peace, when it is used well, can achieve more than war ever does, and King Edgar used it brilliantly.

The shires, the districts of the country, were reorganised, each one governed by a sheriff, a royal officer who answered directly to the king. The hundreds, smaller divisions within each shire, were established as units of local justice and taxation. The towns were strengthened and defended. An elaborate system of courts, running from the borough up through the hundred to the shire, maintained law and order across the country. There was one coinage, one system of weights and measures, one written language that all educated men could read, a King’s English. If you had stood in any market town in Edgar’s England, you would have found the same silver penny bearing the king’s name in your hand whether you were in Winchester or York.

And alongside this political rebuilding came something else. A great revival of monastic life and learning swept through England, led by three extraordinary churchmen. The greatest of them was Dunstan, the Archbishop of Canterbury, a man of exceptional ability who had served as advisor to kings since he was young. Dunstan was not just a churchman. He was a silversmith who made church plate with his own hands, a musician who composed hymns, a painter who illuminated manuscripts, and a scholar whose learning was famous across Europe. Under his guidance, and with the help of Oswald, the Bishop of Worcester, and Ethelwold, the Bishop of Winchester, monasteries across England were reformed and renewed. Monks who had become lazy were called back to strict observance. New houses were founded. Old ones, some of which had lain in ruins since the Viking wars, were rebuilt.

And from these monasteries came the most beautiful illuminated manuscripts in Europe, works of art that were prized across the continent, their pages blazing with gold leaf and rich pigments ground from lapis lazuli and other precious minerals, their text written in ink made from oak galls and iron. Many of these books were written not in Latin alone, but in English. The Catholic Homilies of Ælfric, Abbot of Eynsham, are considered the first great achievement of English as a literary language, the earliest everyday language books in Europe to reach that distinction. What King Alfred had begun, with his patient translations by candlelight, had blossomed into a national literature.

King Edgar’s magnificent coronation at Bath in 973, a ceremony on which every English coronation since has been based, seemed to set a seal on everything that had been achieved. The island was civilised, unified, and at peace. The arts of building and decoration were reviving. Learning was flourishing again. From whatever direction you looked at it, tenth-century England was a country that had pulled itself out of the fire and built something extraordinary.

And then it fell apart.

King Edgar died in 975, and the succession was disputed. His elder son Edward, still a teenager, was murdered at a royal estate in Corfe, Dorset in 978, probably on the orders of his stepmother, who wanted the crown for her own son. That son was a boy of about ten years old, and his name was Ethelred.

History remembers him as Ethelred the Unready. The nickname does not mean what it sounds like. In Old English, his name Æthelred means ‘noble counsel.’ The nickname Unræd means ‘ill-counselled’ or ‘without counsel.’ It is a bitter pun. The king whose name meant good advice was the king who never took any.

In 980, the raids began again.

This time the Vikings were not settlers looking for land. They were professionals, armed and organised, sailing from Scandinavia and Denmark in fast, well-built ships, looking for silver. And they found a country that had grown soft.

The town of Chester was ravaged from Ireland. The people of Southampton were massacred. Thanet, Cornwall, and Devon all suffered butchery and pillage. The raiders came, they burned, they killed, and they sailed away before anyone could stop them.

In 991 a large Danish force landed on Northey Island, a tidal island in the Blackwater estuary in Essex, near the town of Maldon. It is a bleak, flat place even now, surrounded by salt marsh and mudflats, the kind of landscape where the wind never stops and the sky is enormous. A narrow causeway, submerged at high tide, connects the island to the mainland. Facing the Danes from the southern bank stood an English army led by Byrhtnoth, the ealdorman – the local lord of Essex, a tall, white-haired warrior who had served England his entire life.

The Vikings called across the water. They offered the usual bargain. Pay us silver, they said, and we will go away. Buy off this storm of spears before we share the bitter war.

Byrhtnoth’s reply was magnificent. He told the invaders that the English would give them spears and swords, not silver. He told them that an earl stood here, not a coward, with men who would defend their homeland, their prince’s people and fields. The heathen would fall in battle.

And then Byrhtnoth made a terrible mistake. The causeway was flooded, and the Vikings could not cross. All he had to do was wait. But as the tide went out and the path appeared, glistening with mud and seaweed, Byrhtnoth, in a gesture of warrior honour that belonged to an older, simpler age, allowed the Danes to cross and form up on the southern bank so that the battle could be fairly fought.

It was a catastrophe. The English were overwhelmed. Byrhtnoth was killed. Many of his men fled. A small group of his thanes – noblemen, knowing that all was lost, fought on around their lord’s body until every one of them was dead. An Old English poem, ‘The Battle of Maldon,’ preserves their last stand, and it is one of the most moving pieces of writing to survive from this period. But courage and poetry could not save England from what came next.

King Ethelred’s answer to the crisis was money.

In 991 he paid the Vikings ten thousand pounds of silver to go away. They went. They came back. In 994 he paid sixteen thousand pounds. In 1002, twenty-four thousand. Each payment bought a shorter peace than the last. Each time the Vikings returned hungrier and bolder, because they had learned that England would always pay.

The money had to come from somewhere, and it came from the people. The Danegeld, as the tax was called, was wrung from a country that was already bleeding. Farmers, merchants, monks, ordinary families who had nothing to do with the wars of kings, all of them were stripped of whatever they had to fill the purses of men who would only come back for more.

And then Ethelred did something worse than paying. In 1002, on St Brice’s Day, the thirteenth of November, he ordered the killing of every Dane living in the south of England. Not enemy soldiers. Settlers. Families. People who had lived on English soil for a generation or more, who farmed English land, married English men and women, and lived in peace. The massacre was carried out. Among the dead was Gunnhild, the sister of Sweyn, the King of Denmark.

Sweyn swore revenge. For two years his armies ravaged the country, sacking Exeter, Wilton, Norwich, and Thetford. Only famine drove them away, and only for a season. They came back. By 1006, Sweyn was ravaging Kent, burning Reading and Wallingford. Ethelred paid again, this time thirty-six thousand pounds of silver, the equivalent of three or four years of national income, for another truce that would not hold.

In their desperation the English built a fleet. Poor, broken, starving people who had been pillaged to the bone somehow found the strength to construct an immense number of ships, and the new fleet was assembled at Sandwich in 1009. Then the commanders quarrelled. Some ships were sunk in the fighting between the English themselves. Others were lost in a storm. The rest were abandoned. The Anglo-Saxon Chronicle records the moment with quiet fury: ‘And then afterwards the people who were in the ships brought them to London, and they let the whole nation’s toil thus lightly pass away.’

The last recorded Danegeld payment, in 1012, was forty-eight thousand pounds of silver. To enforce its collection, the Vikings sacked Canterbury and took the Archbishop, Alphege, hostage. When Alphege refused to allow his people to be squeezed for his ransom, the Danes killed him at Greenwich, pelting him with bones and ox heads at a drunken feast before one of them struck him down with an axe.

In 1013 Sweyn came again, this time with his youngest son, a prince named Canute. The Yorkshire Danes submitted at once. The Five Boroughs of the Danelaw followed. Oxford and Winchester were sacked. London held out for a time, but it was no use. Sweyn was proclaimed King of England, and Ethelred fled across the Channel to Normandy, whose duke’s sister he had married.

Sweyn died suddenly at the beginning of 1014, and the English, with nowhere else to turn, sent for Ethelred, declaring that no lord was dearer to them than their natural lord, if only he would rule them better than he had done before.

He did not.

But at this darkest moment, one last flame of Alfred’s bloodline rose. Ethelred’s son Edmund, still barely twenty, took matters into his own hands. Though his father declared him a rebel and refused to support him, Edmund gathered forces and struck back. He won battle after battle. He relieved London when Canute’s army had it under siege. He fought with such ferocity and such stubborn, reckless courage that men who had given up all hope began to believe again. New forces sprang from the ruined land. When Ethelred finally died, worn out and useless to the last, Edmund was acclaimed king by the people of London. They called him Edmund Ironside, and for a few blazing months it seemed as though the spirit of King Alfred the Great had returned.

He was strong enough to force a partition of the kingdom, dividing England with the young Danish prince Canute. He was gathering his strength for the next round of the struggle when, in 1016, at the age of twenty-two, Edmund Ironside died. Some said he was murdered, but no one knows for certain.

With him died the last hope of the Saxon line.

The lords of England, gathered at Southampton, agreed to abandon the descendants of Ethelred for ever and recognise Canute as King. The last sons of the house of Wessex fled into exile. The people submitted. The long resistance, which had begun with King Alfred standing in the marshes a hundred and forty years before, was over.

Everything King Alfred had built survived, the shires, the courts, the coinage, the written language, the idea of England itself. These things were too deep in the soil to be uprooted, even by conquest. But the royal house that had built them, the warrior dynasty that had beaten the first Vikings and forged a kingdom from a patchwork of squabbling tribes, was finished. Its last prince lay dead at twenty-two. His surviving children were scattered across Europe, living on the charity of foreign courts.

England itself though endured. It had a name, a language, a law, and a shape on the map that no invasion could undo. But the men who created it were gone. And across the narrow sea, in a hard, well-organised duchy on the coast of France, a young duke was growing up who would one day claim that everything they had built belonged to him. He would go on to become William the Conqueror, but that was still decades away.

In the year 878, after seven years of war against the Vikings, King Alfred of Wessex had won his great victory at the Battle of Edington. The Viking army, starving and desperate behind the walls of Chippenham, had surrendered. Their war-leader Guthrum had knelt in a small Saxon church at Aller, in the Somerset marshes, and received Christian baptism, with Alfred standing as his godfather.

A treaty followed. By 886, after Alfred had recovered London, a formal agreement had been drawn up between Alfred and Guthrum. A line was drawn across the country, running up the Thames, up the river Lea, and then straight to Bedford and beyond, dividing the island between the English and the Vikings. Everything to the east and north of that line became the Danelaw, where Viking customs and Viking law prevailed. Everything to the south and west remained English.

It was not a perfect peace. There would be more fighting in the years to come. But for the first time since the Vikings had arrived in England, the two peoples who had spent a generation trying to destroy each other, had agreed to live side by side. And in the terms of the treaty, something new had appeared. The treaty document between Alfred and Guthrum does not speak of Wessex, or of the West Saxons. It speaks of the English. Alfred was no longer just the King of Wessex. He was becoming the king of a new English nation.

And now he turned his attention to something much harder than fighting – building.

It is easy enough to admire a king who wins battles. King Alfred had done that, against terrible odds, and the story of Edington and the marshes would be told for a thousand years. But what King Alfred did in the years after his great victory was, in many ways, more remarkable than anything he did on the battlefield. He looked at his battered, exhausted kingdom and asked a question that very few warrior-kings have ever thought to ask.

Why did I nearly lose?

The answer, when he found it, was not about courage, the Saxons had plenty of that. It was not about loyalty, or faith, or the willingness to fight. It was about organisation. The Vikings had been able to ravage through England because the English had no permanent defences, no standing army, and no way to respond quickly when an attack came. Every time the enemy appeared, the king had to send out messengers, wait for farmers to leave their fields, gather a militia, march it to the right place, and hope to arrive before the damage was done. And every time the militia had served its forty days, the men went home to tend their crops, and the country was undefended again.

King Alfred set about fixing this with the methodical intelligence of a man who understood problems and was good at solving them.

The first thing he changed was the fyrd.

The fyrd was an old system, and it was simple. Under the fyrd, when the king called, every freeman of fighting age was expected to come, bringing his own weapons and supplies. He served for a set period, usually around forty days, and then he went home. The fyrd was a citizen army, not a professional one, and it worked well enough in peacetime or for short campaigns.

Against the Vikings however, the fyrd had been a disaster.

The Vikings were professional soldiers. They did not go home after forty days. They stayed in the field for months, even years, moving fast, striking without warning, and waiting for the Saxon militia to give up and disperse before attacking again.

King Alfred’s solution was elegant. He divided the fyrd into two halves. While one half served, the other half stayed home and worked the land. When the first half’s time was up, the second half took over. This meant that there was always a force in the field, always men under arms, and always someone tending the crops so that the fighting men had food to eat. It sounds obvious now, but at the time, it was revolutionary. No English king had ever attempted it until King Alfred did.

The fyrd armies were smaller, but they were reliable. King Alfred no longer had to gamble everything on a single muster that might melt away after a few weeks. He had created something closer to a standing defence, a force that could match the Vikings’ endurance without starving the country that supported it.

But an army, however well organised, needs somewhere to stand – to live, when not fighting. King Alfred’s second great reform was the building of the burhs.

A burh was a fortified town. Not a castle, not a military camp, but a walled settlement where ordinary people lived and worked, protected by ditches, earth ramparts, and timber palisades. King Alfred planned a chain of these burhs running down the Channel coast, across to the Severn estuary, and back along the Thames valley, so that no part of southern England was more than a day’s march from a defended position.

Each burh was assigned a contributory district, a surrounding area of countryside whose people were responsible for manning the walls and keeping the fortifications in repair. The system was laid out in a remarkable document called the Burghal Hidage, which lists every burh and specifies exactly how many men were needed to defend it, calculated by the length of its walls. It is the kind of detailed, practical planning that most medieval kings had never attempted before. King Alfred did not just build defendable towns, he built a system to ensure it could be maintained and work.

The burhs changed the nature of the war. Before King Alfred, a Viking raiding party could land on the coast, ride inland, burn and plunder, and be gone before any organised defence could reach them. Now they faced a landscape studded with fortified positions, each one garrisoned and ready. A raiding party that rode past a burh risked being cut off from behind. A Viking army that tried to besiege one would find itself pinned down while the fyrd gathered to attack from neighbouring burhs.

Burhs were not glamorous, the age of beautiful stone castles was still hundreds of years away, but they worked. Building them was slow, patient, expensive work of digging ditches, raising embankments, cutting timber, and convincing local communities to maintain defences that they hoped would never be needed. It was the work of a builder, not a warrior. And it saved England.

King Alfred also looked to the sea. The Vikings’ greatest advantage had always been their ships. They could appear anywhere on the coast, strike, and vanish before a land army could respond. If England was to be safe, it needed ships of its own.

The king designed new vessels. The Saxon Chronicle describes them in some detail: long-ships that were well-nigh twice as long as the Viking vessels, some with sixty oars or more. They were both swifter and steadier and higher than the Viking ships. King Alfred did not simply copy the enemy’s design. He studied it, thought about what made the longships effective, and tried to improve on them.

It was a bold experiment, and like many bold experiments, it did not go entirely to plan. The big ships were difficult for their inexperienced crews to handle. In one early battle, when nine English ships engaged six Viking vessels, several of King Alfred’s fleet ran aground. The Chronicle records that only two enemy ships were captured, and the crews were executed by hanging at Winchester.

It was not yet the Royal Navy. But it was the beginning of the idea that a navy would define England’s future for a thousand years: that an island must command the sea around it to be safe.

With the fyrd reorganised, the burhs built, and the first English fleet at sea, King Alfred turned to the thing that perhaps mattered most to him. The law.

His Book of Laws, known as King Alfred’s Dooms, was not an entirely new creation. King Alfred was too careful, too respectful of what had come before, to sweep away centuries of custom. Instead he gathered the existing laws of Kent, Wessex, and Mercia and wove them together with Christian teaching and the old Germanic customs that still governed everyday Saxon life. He took the code of Moses from the Bible and blended it with the practical traditions of the people he ruled.

At the heart of his code was a principle that he adapted from the Gospels. The Golden Rule says, ‘Do unto others as you would that they should do unto you.’ King Alfred turned it around. His version was more cautious, more realistic, more suited to a world where people could not always be trusted to be good: ‘What ye will that other men should not do to you, that do ye not to other men.’

Do not do to others what you would not want done to yourself.

It is the same idea, but from the other direction. Instead of asking people to be generous, it asks them not to be cruel. And King Alfred added an instruction for judges: put yourself in the other person’s place, and consider what judgement would satisfy you, if you were the one seeking justice.

In the preamble to his new laws, King Alfred wrote something even more remarkable. He explained, modestly, that he had not dared to set down too many laws of his own, ‘for I cannot tell what will meet with the approval of our successors.’ A king who had defeated the greatest military power in northern Europe, who had saved his country from conquest, who had every right to impose his will on anyone, chose instead to say: I do not know what future generations will want. I will leave room for them.

The laws of King Alfred, continually added to by his successors, grew over the following centuries into the body of customary law that became the foundation of English Common Law, the legal tradition that still governs not only England but much of the world.

King Alfred cared about the law because he cared about fairness and justice and learning. A kingdom without educated people could not be justly governed, because the men who administered the law and ran the churches could not read the books that told them how to do it.

The state of learning in England at the time appalled him. King Alfred wrote a letter to the Bishop of Worcester that has been preserved, and its words are worth reading because that letter tell us more about King Alfred the man than almost anything else he wrote.

King Alfred recalled how there had once been wise men throughout England, in both the Church and ordinary daily life, and how kings had obeyed God while keeping peace and enlarging their territory. He remembered how foreigners had once come to England to seek wisdom and instruction. He said with sadness, that learning had fallen away so badly that there were very few men left who could understand their service books in English, or even translate a letter from Latin.

King Alfred understood that a country which cannot read its own laws, its own history, and its own prayers is a country in danger of losing itself. The Vikings had burned the monasteries where learning lived. The books had been destroyed, and the teachers killed. A whole generation had grown up without the knowledge that had once made England one of the most learned kingdoms in Europe.

King Alfred set about restoring that learning. He invited scholars from across the kingdom, from Wales, and from the Continent. He established schools. He translated books from Latin into English himself, working through them slowly and carefully, so that ordinary people who could not read Latin might be able to read them.

And he did something else, something that would prove more lasting than any fortress or fleet of ships. He commissioned the writing of the Anglo-Saxon Chronicle, a year-by-year record of events in England, beginning with the coming of the Romans and continuing through his own reign and beyond. It was kept up by monks in various monasteries for more than two centuries after King Alfred’s death, and it remains one of the most important historical documents in the English language. Without it, we would know almost nothing of this period. King Alfred did not just make history. He made sure it was written down.

All of these reforms were tested in 892, when the Vikings came again.

This time the invasion was enormous. Two hundred and fifty ships appeared off the Kent coast, carrying a great Viking army that had spent years ravaging France. They had besieged Paris itself, battered at its walls for more than a year, and failed to take it. Beaten on the Continent, hungry and restless, they turned once more to England.

They were followed by a second fleet of eighty ships under a war-leader called Hæsten, who sailed up the Thames and fortified himself on the southern bank at Milton, near Sittingbourne. Kent was caught between two Viking forces, attacked from the north and south at once.

But England in 892 was not the England of 878. The burhs held. The reorganised fyrd could keep men in the field for months without the army melting away. King Alfred’s son Edward, still in his early twenties, proved himself a formidable commander. His son-in-law Ethelred of Mercia fought alongside him. The old king, worn down by illness, was not always at the head of the armies now, but his system held, and the young leaders he had raised struck hard.

At Benfleet, on the Thames below London, King Alfred’s forces stormed the Viking camp, captured Hæsten’s wife and his two sons, and burned every ship they could not carry away. When a railway was being built a thousand years later, workmen found charred ship timbers and skeletons in the earth.

And then King Alfred did something that baffled his own people. He sent Hæsten’s wife and sons back.

The wife he returned on simple grounds of humanity. The two boys he returned because they had been baptised as Christians. King Alfred was godfather to one of them, Ethelred of Mercia, to the other. They were Christian brothers, and King Alfred would not punish children for their father’s war.

His people were furious. The kingdom was fighting for its survival against brutal raiders, and the king was sending hostages home out of mercy. It made no sense to them. But this single act, above all others, is the reason why King Alfred is now called ‘the Great.’ Not from his battles, his laws, the ships or the burhs, but because of mercy.

The war ground on for four more years, but the Vikings could not break through. In 896 it ended. The great army dispersed, some settling in the Danelaw, some drifting back to France. The Chronicle, summing up years of desperate fighting in a single weary sentence, declared that by God’s mercy the Viking army had not afflicted the English people too greatly.

King Alfred died in 899. He was about fifty years old, which was old for a man who had spent his life at war and had suffered from painful illness since his youth. He was buried at Winchester, the capital of Wessex, in the Old Minster. Later his body was moved to the New Minster, and later still to Hyde Abbey, just outside the city walls. By the time of the dissolution of the monasteries, six hundred years after his death, the exact location of his remains had been lost. A single bone fragment, found during excavations in 2014, may belong to King Alfred or to his son Edward, but no one can say for certain. The greatest English king lies in an unmarked and unknown grave.

King Alfred left behind a kingdom that had been transformed. When he became king at twenty-two, Wessex was the last Saxon kingdom standing, battered, isolated, and on the edge of destruction. When he died, England south of the Humber was united, defended, and governed by law. The fyrd could be called and kept in the field. The burhs guarded the coasts and the river valleys. Ships patrolled the Channel. The laws were written down.

He left behind a son, Edward, who would carry the work forward with the same energy and skill. And he left behind a daughter, Æthelflæd, who would become the Lady of the Mercians and prove herself one of the most remarkable leaders of the age, conquering Leicester and receiving offers of submission from as far north as York.

But perhaps the most lasting thing King Alfred left behind was the idea that a king’s job was not just to fight, but to build. Not just to win battles but to make laws, teach children, write books, design ships, plan towns, and think carefully about what kind of country his people deserved to live in.

He was not called ‘the Great’ in his own lifetime. That title came later, when people looked back and tried to find a word large enough to contain everything King Alfred had done. He is the only English monarch ever to receive it.

The boy who had visited Rome, the young prince who had charged like a wild boar at Ashdown, the fugitive king who had burned the cakes in a cowherd’s cottage, the commander who had stepped out of the marshes to rally his people at Egbert’s Stone, had become something more than a warrior or a survivor. He had become a builder, and the things he built, the laws, the defences, the learning, the very idea of England itself, outlasted everything the Vikings ever destroyed.

It had been continuously raining for months.

The rain fell on the marshes of Somerset in great grey curtains, hammering the shallow water, drumming on the dead reeds, turning the world into a flat, drowned wilderness where land and water were no longer two separate things. There were no roads here, no villages, no church towers on the horizon. Just water and mud and the low black shapes of alder trees standing in the flood like sentries who had forgotten what they were guarding.

Somewhere in this desolation, in the early weeks of 878, a small group of men moved through the wetland, knee-deep in freezing water, carrying what little they had on their backs. They were exhausted, miserable and hungry. Some of them were wounded, and they had been walking for days, sleeping where they could, and eating what they could find or steal.

At the centre of the group was a man of about twenty-eight. He was not tall, not especially strong, and he had been ill on and off for most of his adult life with a painful condition that could strike him at any moment. He was the King of Wessex, the last Saxon kingdom left standing, and at this moment he was the most hunted man in England.

His name was Alfred.

To understand how a king came to be wading through a swamp with a handful of followers, hiding from an enemy that had conquered almost everything, we need to go back seven years.

Alfred had never expected to be king. He was the youngest of four brothers, the fifth son of King Ethelwulf of Wessex, and in the ordinary way of things the crown would have passed through all of his elder brothers before it ever reached him. But these were not ordinary times. The Great Heathen Army, which had landed in East Anglia in 865, had torn through one Saxon kingdom after another, and the fighting had killed Alfred’s brothers one by one.

His eldest brother, Ethelbald, had already died before the full attack came. His brother Ethelbert ruled briefly and died. His brother Ethelred became king in 866, just as the Viking army was ravaging the north, and Alfred rode at his side as his second-in-command.

They were different men. Ethelred was deeply devout, a king who believed that faith and prayer were the weapons that would defeat the heathens. Alfred believed in God too, but he placed his trust in policy and arms. He was practical, clear-eyed, and willing to act outside his Christian faith.

In January 871, the two brothers faced the Viking army on the Berkshire Downs, at a place called Ashdown. The Vikings had fortified themselves at Reading and were moving westward into the heart of Wessex. Both armies divided their forces into two commands, and the two sides advanced towards each other across the chalk hills.

The Vikings came up the slope with their brightly painted shields and golden arm-rings, clashing their weapons and raising long, defiant war-cries. They looked fierce and amazing. In comparison, the West Saxons, looked plain and weak.

Meanwhile, Ethelred was in his tent, praying. He had been praying for some time.

The two armies were closing in, and King Ethelred’s commanders sent urgent messages. The battle was about to begin, and the King must come. Ethelred replied that he had not finished his prayers. God came first.

Alfred, commanding the other half of the army, watched the Vikings getting closer and made his decision. He could not wait any longer. According to Bishop Asser, who had the account from people who were there, Alfred charged forward like a wild boar and led his men into the Viking lines before his brother arrived on the battlefield.

The fighting raged for hours around a single stunted thorn tree that stood alone on the hilltop. Asser saw the tree himself years later, and noted its position. The two sides hacked at each other with sword and axe, the Saxons pushing uphill, the Vikings holding the higher ground. When Ethelred finally arrived, his prayers completed, the battle intensified further.

At last the Vikings broke. They fled back towards Reading, and the Saxons pursued them through the night, right across the Berkshire hills. Among the dead, they found a Viking king and five of his earls.

It was the very first time the invaders had been beaten in open battle, and Alfred had proved that the Saxons could stand against the Vikings and win. But it was not enough.

All through 871, the fighting went on. Battle after battle, month after month. The Vikings were reinforced from overseas, fresh warriors arriving hungry for land and silver. The Anglo-Saxon Chronicle records seven or eight engagements that year, and the Vikings won the battle more often than not. At Wilton, barely a month after Alfred became king following Ethelred’s death from illness, the Saxons were defeated in the heart of their own country, tricked by the Vikings’ favourite tactic of a feigned retreat.

Alfred was barely twenty-two years old, newly crowned, and already losing.

He did something that must have been agonising for a proud man. He made peace with the Vikings and paid them to leave. The Anglo-Saxon Chronicle records it with blunt brevity: the Saxons made peace with the heathen on the condition that they should depart, and this they did. But they took three or four months before leaving, waiting for the money to be counted and handed over.

It was not a victory. It was a purchase of time. Alfred had bought five years, and he used every one of them.

During those five years of uneasy peace, the shape of England changed.

The Vikings who had come to raid were now settling. The warriors of one decade became the farmers and landowners of the next. They divided the conquered land among themselves, built fortified towns across the east and the Midlands, and planted themselves deeply in the English soil. The whole eastern half of England, from the Humber to the Thames, became Viking territory, and the people who lived there learned to live under Viking law.

The old kingdoms were gone. Northumbria, which had once stood at the forefront of European learning and culture, was broken. East Anglia had been conquered and its king martyred. Mercia, the great kingdom of the Midlands, had been reduced to a puppet state, with its king doing as he was told.

Only Wessex remained.

Alfred used the five year breathing space to strengthen what he had. He studied the problem of defence with the careful, practical intelligence that would mark everything he did. The old system of the fyrd, the part-time militia of farmers who served for forty days and then went home, had been proved hopelessly inadequate against a professional enemy that never went home . Something had to change.

But the full scale of Alfred’s reforms would come later. For now, the truce held, the Vikings farmed their new lands, and Alfred watched and waited.

Then, in the last months of 877, a new Viking war-leader named Guthrum brought his army to the borders of Wessex. He had been probing Alfred’s defences for two years, and what followed was a campaign of treachery and broken oaths that pushed Alfred to the very edge.

First, Guthrum occupied Wareham, close to Portland Bill on the Dorset coast, where a sea army joined him in Poole Harbour. Alfred hemmed in the land army and offered terms. The Vikings took his gold, swore peace on their most sacred object, the Holy Ring, and promised to depart.

Then, in the middle of the night, they broke every oath and rode for Exeter.

Alfred, gave chase, but arrived too late. The Vikings had locked themselves inside a fortress and could not be reached. But a storm smashed the Viking fleet as it tried to round the coast to join them. A hundred and twenty ships were wrecked near Swanage, and perhaps five thousand men were drowned. Guthrum, trapped in Exeter without his fleet, agreed to another peace, this time with oaths of still greater solemnity.

He kept the peace for five months.

In January 878, in the dead of winter, Guthrum struck.

Alfred’s court was at Chippenham in Wiltshire. It was Twelfth Night, the feast of Epiphany, and the Saxons were celebrating. Whether they were feasting, or praying, or simply exhausted after the long months of tension, they were not ready for what came next.

The Viking army attacked Chippenham without warning. The army of Wessex, the only force left in England that could resist the Vikings, was shattered in a single night. Men were killed where they stood. Others fled to their homes. Some abandoned the country altogether, crossing the sea to seek refuge at the court of France.

Alfred, with a handful of his closest men, escaped into the countryside.

This was the lowest point. The kingdom that had held out for seven years against the Vikings was broken. The Vikings controlled Wessex. Alfred was a fugitive in his own land, moving through forests and marshlands with no army, no fortress, and no certainty that anyone would follow him again. He had nothing.

He made his way to the Somerset Levels, the great expanse of waterlogged marshland that stretched between the Quantock Hills and the Mendips. In the middle of this wilderness, barely rising above the flood, lay a small patch of higher ground called Athelney, the Isle of Athelney, surrounded by impassable bogs of alder and willow.

Here Alfred hid.

For several months, through the worst of winter and into the early spring, the King of Wessex lived as an outlaw. He and his small band survived on whatever they could find or take, hunting in the marshes, raiding Viking supply lines, stealing from anyone, Viking or English, who had submitted to the enemy. Bishop Asser, who knew Alfred and wrote his life, described it plainly: the king led an unquiet life in great tribulation, for he had nothing except what he could seize, either by stealth or by force, from both the heathen and the Christians who had submitted to their rule.

It is from this desperate time that the most famous story about Alfred comes. The tale first appears in a later edition of Asser’s biography, and it has been told and retold for over a thousand years.

The story goes that Alfred, wandering in disguise, took shelter in the cottage of a cowherd. The cowherd’s wife, not knowing who he was, left him by the fire and asked him to watch her bread while she was busy elsewhere. Alfred, deep in thought about his kingdom and his plans, his mind far away from the cottage and the hearth, forgot the bread entirely. When the woman returned she found it burning, and she scolded him furiously.

The words she used, recorded in the original account in Latin verse of all things, were sharp and practical: why have you not turned the bread when you see it burning, especially as you are so fond of eating it hot?

She did not know she was shouting at the King of England.

Nobody knows whether the story is true. It may be a folktale that attached itself to Alfred because he was the kind of king around whom stories gathered. But true or not, it has lasted because it tells a deeper truth. Here was a king so reduced, so stripped of everything, that an ordinary woman could shout at him for burning bread, and he could do nothing but sit there and take it. The distance between the throne at Chippenham and the hearthside at Athelney was the distance between a kingdom and a cooking fire.

But Alfred was not finished. Even in hiding, he kept contact with his people, sending messengers through the marshes to the men of the western shires. He was planning.

While Alfred waited, the Vikings suffered a serious blow in Devon. Twenty-three shiploads of Vikings, having raided the Welsh coast, sailed east and attacked a Saxon stronghold on Exmoor. The garrison was outnumbered and the Vikings expected an easy victory. They laid siege to the place, confident that hunger and thirst would force a surrender.

Instead, the defenders came out at dawn and charged downhill into the Viking lines. They killed the Viking commander and most of his men. Eight hundred Vikings fell. Among the spoils was a banner called the Raven, said to have been woven in a single day by the three daughters of Ragnar Lodbrok. It was believed that the raven embroidered on it would flutter its wings before a Viking victory. On this day, the raven hung limp and still.

The news reached Athelney. Alfred must have felt a surge of hope, but he could not act on hope alone. He needed an army, and for that he needed the men of the western shires to believe he was alive, to believe he could still lead them, and to leave their farms and families and come.

Towards the end of May, Alfred sent out the call. The fyrd , the militia, was summoned. Come to Egbert’s Stone, near Selwood, where the borders of Somerset, Wiltshire, and Hampshire meet.

They came.

The men of Somerset came. The men of Wiltshire came. The men of Hampshire came. They came out of the fields and the villages and the forest clearings, carrying their spears and their shields and whatever weapons they had, and when they saw Alfred, alive and standing before them, the Chronicle tells us they received him as one risen from the dead, and they were filled with great joy.

It is one of the great moments in English history. A king given up for lost, stepping out of the marshes to rally his people for one final battle. Alfred had no certainty that he would win. He knew only that if he did not fight now, while the will to fight still held, the men would drift back to their farms and the chance would be gone.

He marched at once. The Vikings were still at Chippenham, resting on their plunder, and Alfred led his army to Edington, on the edge of the Wiltshire downs, where the two forces met on the bare, open hillside.

Everything depended on this battle. If the Saxons lost, there was nowhere left to fall back to. There would be no more retreats to the marshes, no more truces bought with gold. If Wessex fell, the last Christian Saxon kingdom in England would be gone.

Both armies dismounted. The horses were sent to the rear. The shield walls were formed, two long lines of men with their shields overlapping, packed so close together that they could feel the heat and the breath of the men on either side. And then they walked forward into each other.

The fighting lasted hours. It was the brutal, grinding, exhausting work of the shield wall, pushing, stabbing, hacking with sword and axe, each side trying to break through the other’s line, each side holding, stepping over the fallen, pressing forward into the terrible noise and stink of close combat. The Vikings had not lost the favour of battle in years. The Saxons had everything to lose and nothing behind them but empty country.

Finally, the Vikings broke.

They fled from the battle field, pursued by the Saxons, all the way back to their camp at Chippenham, where they locked themselves behind their walls. Alfred followed and surrounded them. For fourteen days he held them there, and this time there was no escape. No fleet would come. No reinforcements would arrive. The Vikings were starving, freezing, and, as Asser says, full of despair.

Guthrum sued for peace. He offered hostages, as many as Alfred wanted, and promised to leave Wessex immediately. It was the complete surrender of the most powerful Viking army in England.

But Alfred did not do what most men would have done. He did not slaughter the Vikings. He did not even humiliate them. Instead he did something extraordinary.

He invited Guthrum to be baptised.

Three weeks after the surrender, Guthrum and thirty of his leading warriors came to Alfred’s camp at Aller, near Athelney, the very marshes where Alfred had hidden as a fugitive. There, in a small Saxon church, the Viking warlord knelt and received the waters of Christian baptism. Alfred stood as his godfather. He lifted Guthrum from the font, called him his son, and gave him a new Christian name, Athelstan.

For twelve days, Alfred entertained Guthrum and his men. He gave them costly gifts. He treated them not as defeated enemies but as new brothers in the faith.

It was an act of extraordinary imagination. Alfred had Guthrum entirely in his power. He could have starved the Vikings into total submission and executed their leaders. Many of his own people, who had suffered years of burning and killing and plundering at Viking hands, must have wanted exactly that. But Alfred understood something that few leaders in any age have grasped: that a defeated enemy who is destroyed simply creates a space for the next enemy, while a defeated enemy who is brought into the fold may become a lasting neighbour.

Alfred did not try to drive the Vikings out of England. He accepted that they were there to stay. What he wanted was peace, a real and lasting division of the island between the two peoples, with agreed borders, agreed laws, and a shared faith. The conversion of Guthrum was not a humiliation. It was an invitation, and a handshake, and a promise.

In 886, after Alfred had recovered London, a formal treaty was drawn up between them. On Alfred’s side, the document names the counsellors of the English nation. On Guthrum’s side, it speaks of the people who dwell in East Anglia. A line was drawn across the country, running up the Thames, up the river Lea, and then straight to Bedford and beyond by the Ouse to Watling Street. Everything to the east and north of that line became the Danelaw, where Danish customs and Danish law prevailed. Everything to the south and west remained English.

It was not a perfect peace. There would be more fighting in the years to come, more raids, more broken promises. But the treaty of 886 was the foundation on which everything that followed was built. Two peoples, who had spent a generation trying to destroy each other, agreed to live side by side.

And in the terms of that treaty, something new had appeared. For the first time, the document does not speak of Wessex, or of the West Saxons. It speaks of the English. Alfred was no longer just the King of Wessex. He was becoming something larger, something that had not existed before.

He was becoming the king of the new English nation.

One summer day in the year 789, three ships appeared off the coast of Dorset.

They came from the north, from a place called Hordaland on the western coast of Norway, and they were unlike any vessels the people on shore had ever seen. Long and low, with high carved prows and rows of painted shields along their sides, they slid through the water like dark, narrow fish.

A man named Beaduheard, the king’s reeve, a local official whose job was to greet foreign merchants and direct them to the royal town, rode down to the harbour at Portland with a few of his men. He assumed the strangers had come to trade. He spoke to them with the authority of his office and ordered them to accompany him to see the king.

They killed him and all his men there and then, and they returned to their boats and left.

No one in England knew it yet, but this small, violent encounter on a summer afternoon in Dorset was the beginning of something that would tear the country apart for the next two hundred and fifty years. It was the first recorded arrival of the people the English would come to call the Danes, or the Norsemen, or simply – the Vikings.

To understand why the Vikings came, you have to look north.

Far beyond Britain, across the cold grey waters of the North Sea, lay the lands of Scandinavia, the countries we now call Norway, Sweden, and Denmark. These were hard countries, much of them covered in forest, rock, and ice. The growing seasons were short and the winters were long and brutal. The people who lived there were tough, practical, and very good at building things, especially ships.

Nobody drove them out. Unlike the Saxons centuries before, who had come to Britain partly because other peoples were pressing on them from the east, the Scandinavians moved of their own accord. Their population was growing. There were too many sons and not enough land. The younger ones, the ones without an inheritance, looked outward, to the sea, to the horizon, and to whatever lay beyond it.

What lay beyond it, as they soon discovered, was a great deal of wealth, most of it sitting in churches and monasteries with no walls around them and no soldiers to guard them.

The Viking expansion was extraordinary in its reach. One group of raiders and settlers pushed south from Sweden into the heart of what is now Russia, sailing down the great rivers all the way to Constantinople, which is today the city of Istanbul in Turkey. Another group sailed from Norway into the Mediterranean, raiding the coasts of Spain and North Africa. A third group carried the Norsemen westward, to the Scottish islands, to Ireland, to Iceland, to Greenland, and eventually, five centuries before Columbus, to the coast of North America.

One of these groups travelled westward. They came to the British Isles and they fell upon it like ravenous wolves.

Four years after the killing of Beaduheard, the storm broke.

In June of year 793, four years after the killing of Beaduheard and his men, a fleet of Viking ships appeared without off the coast of Northumbria and landed on the island of Lindisfarne, Holy Island, one of the most sacred places in all of Christian England.

Lindisfarne was a monastery, founded over a hundred and fifty years earlier by the Irish monk Aidan, and it had become the spiritual heart of the north. It was the place where the great saint Cuthbert was buried, a place of pilgrimage and prayer, and it was rich. Over the decades, kings and nobles had given it treasures, gold crosses, jewelled reliquaries, fine metalwork, and beautifully illuminated manuscripts. The monks lived quietly, studying and praying, on a windswept island connected to the mainland only at low tide.

They had no weapons. They had no walls. They had no warning.

The Vikings sacked the place. They killed monks, threw others into the sea, and carried away everything of value, the gold, the jewels, the sacred vessels, along with any monks young and strong enough to be sold as slaves in the markets of Europe.

The news of the attack sent a wave of horror across Christendom. Alcuin, a scholar from Northumbria who was living at the court of Charlemagne, the great King of the Franks, whose empire stretched across most of western Europe, wrote home in anguish. In almost three hundred and fifty years, he said, nothing so terrible had ever happened in Britain. That the heathens could sail across the open sea and destroy a place as holy as Lindisfarne seemed impossible, monstrous, a sign of God’s anger.

The following year, the raiders returned and struck at nearby Jarrow. This time the local people fought back. The weather turned against the Vikings, many were killed, and their leader was captured and put to a cruel death. The survivors carried such a grim report back to Scandinavia that the English coasts were left in peace for nearly forty years.

But it was only a pause. The taste for raiding Britain had spread, and the profits were too good to abandon.

But the Vikings could not have attacked Britain (or much of Europe), without one extraordinary object – the longship.

Over many generations, the shipbuilders of Scandinavia had developed and perfected a vessel that was unlike anything else on the water. It was built to do two things superbly well: to cross the open ocean in the worst weather, and to sail up shallow rivers far inland where no deep-keeled vessel could follow.

We know a great deal about these ships because several have been dug up almost complete. The most famous was discovered in 1880 at a place called Gokstad, in Norway, buried in a great mound of earth as part of a chieftain’s funeral. It had lain there for nearly a thousand years, preserved in thick blue clay.

The Gokstad ship was about twenty-four metres long and five metres wide, roughly the length of a tennis court, but narrow and low in the water. She was built of oak, plank by plank, each one overlapping the next and fastened with iron rivets. The planks below the waterline were astonishingly thin, no more than two or three centimetres, which made the hull light and flexible. In heavy seas, the whole ship could bend and twist with the waves rather than fighting them. She had sixteen oars on each side and a single square sail of heavy wool, and she could carry a crew of around thirty-four, with their weapons, food, and supplies, for weeks at a time.

In 1893, a group of Norwegians built an exact copy of the Gokstad ship and sailed it across the Atlantic Ocean from Norway to America. It took them twenty-eight days. The captain reported that the ship moved through the water beautifully, and that even in storms the flexible hull rode the waves as though it were alive.

Imagine that ship approaching your coastline. A low, dark shape gliding out of the morning mist, the carved prow cutting the water without a sound, the rows of painted shields, black and yellow, alternating, catching the early light. Then another ship behind it. Then another. Then a dozens and then hundreds.

That is what the people of England saw, and feared, for year after year, throughout the ninth century.

For a long time, the Viking raids followed a pattern. The longships would appear in spring or summer, the warriors would attack a monastery or a coastal town, take everything of value, and sail home again before winter. It was piracy, brutal, efficient, and immensely profitable.

But as the decades passed, something changed. The raiders began to stay longer. They wintered on the English coast, fortifying their camps with ditches and ramparts, bringing their horses ashore and riding inland to strike at targets that had thought themselves safe. And eventually, behind the raiders, came their families. What had begun as plunder was becoming settlement. What had begun as theft was becoming conquest.

The English were poorly prepared for this kind of enemy. Their system of defence relied on the fyrd, a call-up of local men, who were expected to serve as soldiers for about forty days when summoned by their lord. These men fought bravely enough, but they were part-time warriors with fields to tend and families to feed. When their forty days were up, they went home, regardless of whether the enemy had been defeated. Against an enemy who never went home, who moved fast, who fortified their camps and fought with professional discipline, the fyrd was hopelessly outmatched.

The Vikings were also cunning. They used tricks and stratagems that the straightforward English were slow to counter. One favourite was the feigned retreat, falling back in apparent panic, drawing the English forward into broken ground, then turning and cutting them to pieces. On one famous occasion, a Viking leader besieging a town announced that he was dying and begged the local bishop to give him a Christian burial. The bishop, delighted at the thought of a deathbed conversion, agreed. But when the body of the ‘deceased’ was carried through the town gates for burial, the mourners threw off their cloaks. They were armed warriors, and the sack and slaughter began at once.

The Viking sagas are full of legendary figures, and none is more famous than Ragnar Lodbrok, Ragnar ‘Hairy-Breeches’, a semi-legendary Viking king of Denmark whose story weaves through the royal families of Scandinavia. He was a raider from his youth. In 845 he led a fleet up the river Seine and attacked Paris. Later he turned his attention to Northumbria, but here his luck ran out. According to Scandinavian tradition, he was captured by King Ella of Northumbria and thrown into a pit full of venomous snakes. As the serpents coiled around him, Ragnar sang his death-song to the end.

His final words, so the skalds tell us, were a warning: ‘The little pigs would grunt now if they knew how it fares with the old boar.’

Ragnar had sons, and the stories say each one received the news of his father’s death in a different way. One gripped his spear so hard that the print of his fingers remained on the shaft. Another was playing chess and clenched a pawn until blood started from under his nails. A third was trimming his nails with a knife and kept cutting until he reached the bone. But the fourth son was the one who mattered.

His name was Ivar. They called him Ivar the Boneless.

Whether the story of Ragnar’s death is true, and many historians doubt it, its consequences were terribly real. In the autumn of 865, a vast Viking army landed in East Anglia. The Anglo-Saxon Chronicle calls it the Great Heathen Army, and it was led by Ivar and his brothers. This was not a raiding party. This was an invasion.

The Great Heathen Army was organised on the basis of ships’ companies, but once ashore the warriors seized every horse they could find and became a fast-moving mounted force. They did not fight from horseback – they used the horses for speed, riding hard across country and then dismounting to fight on foot. The Anglo-Saxon Chronicle records the moment with quiet dread: ‘a great heathen army came to the land of the East Angles, and there was the army a-horse.’

Ivar was a commander of brilliance and ruthlessness. He did not simply raid. He planned, he manoeuvred, and he conquered.

The army moved north in the autumn of 866. They crossed the Humber and seized York, the ancient city that had once been the Roman fortress of Eboracum, and was now the capital of Northumbria. The Northumbrians had been fighting among themselves, squabbling between two rival kings, and the Vikings took the city with little resistance.

But in the spring of 867, the two Northumbrian kings put aside their quarrel and united in a desperate attempt to drive the invaders out. They attacked the city in March and at first broke through the walls. For a moment it seemed as though the counter-attack might succeed. But in the narrow streets the Northumbrians lost their advantage of numbers, and the experienced Viking warriors overwhelmed them. Both Northumbrian kings were killed in the slaughter.

That was the end of Northumbria as an independent kingdom. The north of England, the land that had produced Bede, the Lindisfarne Gospels, and the great stone crosses of Anglian art, sank back into darkness. The monasteries were destroyed, the scholars scattered, the libraries burned. A kingdom that had stood at the front of European learning and culture was broken in a single afternoon.

Ivar set up a puppet king in the ruins and moved south.

His next target was Mercia, the great kingdom of the Midlands, which for nearly a century had been the strongest power in England. Ivar brought his army before Nottingham and laid siege to it. The King of Mercia sent desperately for help, and help came, from Wessex. King Ethelred and his younger brother Alfred marched to Nottingham and offered to attack the Viking lines.

But the Mercians chose to negotiate instead of fight, and a treaty was agreed that left Ivar in possession of Nottingham. It was the beginning of the end for Mercia.

Ivar was a strategist who used politics as skilfully as he used his sword. In York and Ripon he had not harmed the churches – he understood that terror was a tool, but so was restraint. He was content to set up obedient puppet rulers in the kingdoms he conquered, draining their wealth and their strength without the expense of holding every field and village by force.

After breaking the treaty of Nottingham, Ivar turned on East Anglia and subjected its king, Edmund, to a dreadful martyrdom. Edmund was later made a saint, and the town where he was buried, Bury St Edmunds, still carries his name.

Then, suddenly, Ivar left England for ever. He returned to Ireland and to Dublin, a city the Vikings themselves had founded, laden with spoils and seemingly invincible. The Irish chronicles record that the king of the Norsemen of all Ireland and Britain died there in 873, struck down by a sudden and terrible disease.

But the army Ivar had built did not leave with him. It stayed, and it grew.

The Danish warriors who had come to raid now settled on the land they had taken. They fortified a chain of towns across the east and the Midlands, Stamford, Nottingham, Lincoln, Derby, Leicester, and these became the strongholds of a new power in England. The soldiers of one decade became the farmers and landowners of the next. They divided the conquered territory among themselves, carved out estates, and planted themselves deeply in the English soil.

One by one, the old Saxon kingdoms fell. Northumbria was gone. East Anglia was gone. Mercia was broken and obedient, its puppet king doing as he was told. The Danes controlled the entire eastern half of England, from the Humber to the Thames and beyond.

Only one kingdom remained. In the south and west, behind the forests and the downlands, Wessex still stood, battered, frightened, but unbroken. Its young king was a man who had already ridden to war at his brother’s side, who had already seen what the Vikings could do. He had watched the other old kingdoms fall, one after another, and he knew that Wessex was next.

His name was Alfred. And in the story of what happened next, the fate of England, the idea of England itself, would hang by a thread.

The villa stood on a hillside above a shallow river in the south of Britain, and for as long as anyone could remember it had been a good place to live.

There were stone floors with patterns set into them – red and white and blue tiles arranged into pictures of dolphins and birds and twisting vines. There was a kitchen garden where herbs grew in neat rows. There was a bathhouse with heated floors – warm air from a furnace flowed through hollow spaces beneath the stone, held up on rows of small pillars, so that the floor itself became hot to the touch. This system is called a hypocaust. On cold winter mornings the household sit in the warm steam of the bathhouse and listen to the cold rain outside.

The family who lived there were not Roman. They were British – people whose ancestors had lived on this island long before the legions came. But they spoke Latin as well as their own tongue. They wore Roman clothes, they drank wine from pottery made in Gaul, and their children were taught to read and write. They paid their taxes, obeyed the Roman laws, and in return the Empire kept them safe.

For nearly four hundred years, this is how life had been. Roads ran straight across the countryside, connecting towns with stone walls and market squares and temples. Roman soldiers stood guard on the great northern wall that the Emperor Hadrian had built from coast to coast to keep out the Pictish tribes of the north. Along the eastern and southern shores, a chain of massive forts watched the grey sea for raiders. In the earlier centuries of Roman rule, a fleet of warships had patrolled the Channel and the North Sea, keeping the shipping lanes open and the pirates at bay.

Britain was not the centre of the Roman world. It was a province on the edge of it, a green and rainy island at the end of the known earth. But it was peaceful, and it was prosperous, and the people who lived in its villas and towns had every reason to believe that life would go on like this for ever.

It didn’t.

By the early part of the fourth century AD – the three-hundreds – things had begun to change. The Roman Empire was enormous, stretching from Britain in the west to the deserts of Syria in the east, and it was starting to crack. There were too many frontiers to defend, too many enemies pressing in from every direction, and not enough soldiers to hold them all back.

In Britain, the trouble came from three sides at once. From the north, the Picts poured over Hadrian’s Wall. From the west, across the Irish Sea, came raiders the Romans called the Scots – though in those days the Scots were Irish, which is confusing but true. And from the east, rowing long wooden boats across the cold waters of the North Sea, came the most feared raiders of all.

The Saxons.

Their very name was said to come from the seax – a short, single-edged sword, the kind of weapon made for close, ugly, brutal fighting. They came from the flat, marshy coastlands of what we now call northern Germany and Denmark, and they came in growing numbers. At first it was raiding parties – a few boats at a time, striking the coast, burning and looting, then rowing home with whatever they could carry. But year by year the raids grew bolder and more frequent, until the people of eastern Britain lived under the same dread of attack from the sea that a later age would know from the air.

The Romans did what they could. They built new coastal fortresses – great thick-walled strongholds at places like Richborough in Kent and Portchester near Portsmouth. They appointed a commander called the Count of the Saxon Shore to defend the eastern coast, just as the Duke of the Northern Marches defended Hadrian’s Wall. In earlier times, the Romans had used specially camouflaged galleys – painted sea-green from hull to sail, the crews’ faces daubed the same colour so that they were nearly invisible on the water. The writer Vegetius tells us they were called the Painted Ones.

But it was not enough. The Empire was pulling its soldiers away to fight more urgent battles elsewhere. In the year 367, the worst happened. The Picts, the Scots, and the Saxons all attacked at the same time, as though they had agreed amongst themselves to strike together. The Duke of the Northern Marches and the Count of the Saxon Shore were both killed. The defences broke open, and the raiders poured through.

They came upon a world of country houses and farms and quiet lanes, and they destroyed it. Homes were burned. Families fled. Somewhere in Suffolk, a wealthy household buried their finest silver – plates, bowls, spoons, a magnificent set of tableware – in the ground, hoping to come back for it when the danger passed. They never did. That silver may have been buried around this time, or perhaps earlier, during some other moment of crisis – no one knows for certain. What we do know is that it lay hidden for well over a thousand years before it was dug up in 1942. You can see it today in the British Museum in London. It is called the Mildenhall Treasure, and it is still very beautiful.

Rome sent help. A general called Theodosius arrived with fresh troops, drove back the raiders, and repaired the defences. But it was like mending a crumbling wall with patches. The patches held for a while, and then the wall crumbled somewhere else.

Again and again, ambitious men in Britain stripped the island of its soldiers and marched them off to the continent to fight for the Imperial throne. A Roman Emperor called Magnus Maximus did it in 383, taking the garrison with him to Gaul. He won his war, ruled for five years, and then lost everything. None of his troops came back. Then another commander did the same thing, and another, each one draining away the defenders who were needed at home.

By the year 410, every last Roman soldier had gone – sent away to fight in wars that had nothing to do with Britain. The Emperor Honorius, besieged in Italy, received one final desperate letter begging for help. His reply was short and bleak. The people of Britain, he said, must look to their own defences.

They were on their own.

What happened next is one of the darkest and most mysterious passages in all of British history, which is why it is know as the Dark Ages. For nearly two hundred years, very little was written down, and what we do know comes from only a handful of sources – a British monk called Gildas, writing around the year 545, the Venerable Bede writing two centuries after that, and a collection of old records that were gathered together in the ninth century and are known as the Anglo-Saxon Chronicle. Between them, they give us a picture, though it is like looking through a window of very old and uneven glass. The shapes are there, but nothing is quite clear.

What we can see is this. Britain did not fall apart overnight. For a generation or more after the Romans left, life carried on. Towns still functioned. The Christian churches were still open. The fields were still farmed. A visiting bishop from Gaul named Germanus came to Britain around the year 429 and found a country that was still wealthy, still organised, still recognisably the same place the Romans had known – but frightened, and at war.

The real catastrophe came around the year 450, when a British chief named Vortigern made a decision that would haunt these islands for ever. Facing attacks he could not repel on his own, he invited a band of Saxon warriors across the sea to fight for him as mercenaries. Their leader was a man called Hengist.

It was a trap – though not at first. Hengist and his warriors came, and they fought, and they were given land in Kent as payment. But the door was now open. More Saxons came, and then more, and then the Angles and the Jutes from further north. What had begun as a hired war-band became a flood of settlers. They came up the rivers and along the coasts, and they did not go home.

The Britons fought back. They fought with desperate courage, and in places they held their ground. The old Roman towns with their stone walls became refuges. In the mountains of the west – Wales, Cornwall, the Lake District – the British held out for generations, pushed back but never conquered.

And somewhere in this long and terrible struggle, there rose a leader whose name has never been forgotten.

Arthur.

No one knows exactly when he lived, or where he fought, or even whether Arthur was his real name. The earliest records call him Dux Bellorum – the war leader – and nothing more. He was not a king in the way we think of kings, with a crown and a throne and a castle. He was a commander, a war captain, a man who gathered the scattered British forces together and led them against the invaders.

What we do know is that somewhere around the year 500, a great battle was fought at a place called Mount Badon. Nobody can say for certain where Mount Badon was – people have argued about it for centuries – but the result is beyond doubt. The Saxons were defeated, so completely and so crushingly that their advance was halted for nearly fifty years. A whole generation grew up in something like peace.

And the name attached to that victory, passed down through the centuries, was Arthur.

That is the seed from which the legend of King Arthur grew. Centuries later, the storytellers took that seed and let it flower into something extraordinary – the Round Table, the sword in the stone, Lancelot and Guinevere, Merlin, the quest for the Holy Grail. Geoffrey of Monmouth wrote it down in the twelfth century. Thomas Malory retold it in the fifteenth. Tennyson gave it new life in the nineteenth. Each generation added its own beauty to the story, until the real Arthur – the war-worn cavalry commander on a muddy British hillside – was wrapped in so many layers of legend that he almost disappeared.

But he was there. Historians have argued about it endlessly, and some have tried to dismiss him altogether, but the latest and best-informed scholars agree that behind the legend there was a real man. A British warrior who gathered horsemen around him – men in armour, perhaps the last to wear Roman-style armour – and rode from one threatened district to another, rallying the local fighters, leading the charge. The Saxons fought on foot with swords and spears and almost no armour. Against mounted, armoured cavalry, they could be beaten.

Arthur held the line. And when he was gone – however he died, wherever he fell – the memory of him became the most powerful story in British history. The hope that he would one day return, the Once and Future King, burned on through the darkest centuries. From Cornwall to Cumberland, every Celtic tribe in Britain claimed him as their own.

But the victory at Mount Badon could not last for ever. The Saxons kept coming. Wave after wave of settlers crossed the North Sea, not just to raid now but to stay. They cleared the forests and drained the valleys. They built farms and villages. They brought their families, their language, and their gods – Thor and Woden, whose names we still carry in Thursday and Wednesday.

The British language faded. Latin vanished. In the places the Saxons settled most thickly, the old British names for things survived only in the names of hills and rivers and streams – ancient Celtic words still hiding inside the English landscape like fossils in rock.

What grew in the place of Roman Britain was something entirely new. Not one kingdom but many – a patchwork of small, fierce, quarrelling Saxon territories that later historians would call the Heptarchy, the seven kingdoms. Northumbria in the north. Mercia in the midlands. East Anglia in the east. Essex, Sussex, Wessex, and Kent in the south. There was no single English king, no unity, no common purpose. Their boundaries shifted constantly as one ruler rose and another fell. They fought each other as readily as they had fought the British, and for a long time there was no order and no peace.

Then Christianity returned.

It came from two directions at once, like two streams flowing towards the same valley.

The first stream came from Ireland. A young Romano-British man named Patrick had been captured by Irish raiders as a boy and carried across the sea into slavery. For six years he tended pigs in the Irish hills before he escaped and eventually found his way home. But something had changed in him during those years of captivity, and he went back to Ireland as a missionary, carrying the Christian faith to the people who had enslaved him. Patrick’s church took root and flourished, and from Ireland the Gospel spread northward. A monk named Columba, born half a century after Patrick’s death but burning with the same fire, sailed to the tiny windswept island of Iona off the west coast of Scotland and founded a monastery there. From Iona, his followers carried Christianity into the north of Britain. One of them, a gentle and tireless monk named Aidan, crossed to the Northumbrian coast and founded a new monastery on the island of Lindisfarne.

The second stream came from Rome. Pope Gregory chose a monk named Augustine and sent him across the sea to bring Christianity to the English. Augustine landed in Kent in 596, because Kent was the kingdom closest to the continent, and its king, Ethelbert, had already married a Christian princess from the Frankish court. Augustine converted Ethelbert and established his church at Canterbury, which has remained the centre of English Christianity ever since.

But the two streams of the faith were different in character. The Roman monks reported to the Pope in Rome and followed the customs of the wider European Church. The Celtic monks of Ireland and Iona lived in small, scattered communities and answered to their abbots. They even disagreed about when to celebrate Easter, and about how to cut a monk’s hair – which may seem trivial now but mattered enormously then, because it touched on the question of who had the right to say how Christians should live.

The argument was settled at a gathering in a Northumbrian monastery in the year 664 – the Synod of Whitby. The king himself sat and listened while monks from both traditions argued their case, and in the end he decided in favour of Rome. From that moment, England was part of the wider Christian world, connected to the same Church that stretched across the whole of Europe.

Monasteries were built, and in them monks began to write – to copy out the scriptures, to record the history of their own times, to create works of astonishing beauty. On the island of Lindisfarne, a monk painted a copy of the four Gospels by hand, every letter shaped with care, every page alive with colour and pattern. The Lindisfarne Gospels are among the most beautiful books ever made, and they survive to this day.

In a monastery at Jarrow, in the far north of England, another monk named Bede spent almost his entire life reading, writing, and thinking. He barely travelled beyond the walls of his monastery, yet he became the most learned man in Europe and became known as the Vernerabel Bede. His great work, a history of the English Church, is one of the earliest and most important books of English history, and we still read it today. It is Bede we have to thank for the practice of numbering our years from the birth of Christ – a system the whole world now uses.

Two great kings eventually rose above the chaos of the Heptarchy to claim something close to rule over all the English south of the River Humber. Ethelbald of Mercia reigned for forty years, and his successor Offa for another forty. Offa was the more remarkable of the two. He corresponded as an equal with Charlemagne, the King of the Franks, who ruled most of western Europe from his court in what is now France and Germany. Charlemagne was the most powerful ruler in the western world, and to be treated as his equal was no small thing. When the great king proposed a marriage between their children, Offa calmly insisted that the arrangement must go both ways – his son must marry a Frankish princess in return. Charlemagne was furious at first, but he came round. You do not argue long with a man whose trade you need.

Offa built a great dyke – a massive earthwork running from the mouth of the River Severn to the neighbourhood of the Mersey – to mark the boundary between Saxon England and the unconquered British lands to the west. Offa’s Dyke still runs across the hills and valleys of the borderlands today. To build it required enormous labour and iron authority. It tells you everything about the kind of kingdom Offa commanded.

One of his coins tells a different story, and a rather funny one. It is a gold coin, carefully copied from an Arabic original, and stamped with the words Offa Rex. The die-cutter who made it had copied the Arabic inscription as well, treating it as decoration – he clearly had no idea what the flowing script meant. Nobody noticed that it declared there was no God but Allah. The coin was found in Rome centuries later. How it got there, nobody knows for certain, though some have guessed it was sent as a gift to the Pope. One trusts that nobody in Rome could read Arabic either.

By the late eighth century, England was Christian, increasingly literate, and beginning to produce scholars and artists whose work was admired across Europe. There was, at last, the faint outline of a nation. Not yet united, not yet at peace, but alive, and recognisably English. The old Roman world was gone. The British had been driven to the mountains and the western coasts. The darkness of the invasion years had lifted, and in its place stood something new – rough, quarrelsome, often brutal, but full of energy and a stubborn will to build.

And then, on a June day in 793, raiders from across the North Sea fell upon the monastery at Lindisfarne and tore it apart.

But that is the next story.

For the past three months I have been writing about the ongoing human need to make things with care. From stained glass and illuminated manuscripts to a world made by a philologist who loved languages more than fame.

Last week, I discovered an almost forgotten (here in the UK) Victorian educator who believed that children are born persons – not empty vessels to be filled, but living minds that deserve the finest ideas we can offer them. Charlotte Mason.

Finding this incredible woman has been a catalysing moment for me, and she is the inspiration behind my new publication.

I am particularly passionate about stories for children.

My other passion is history, and I strongly believe that history should be passed on to children via story.

Charlotte Mason is the inspiration behind my new publication, Flint & Fable. It will become a platform for a serialised narrative history of Britain, written specifically for young readers age 10 to 13.

It is not a textbook or a worksheet; it is a living book – history told as a serialised story, the way history always used to be told.

I have created Flint & Fable because I firmly believe that children who encounter history as story remember it for the rest of their lives.

Flint & Fable launches with the Anglo-Saxon kingdoms and the Viking longships, moves through the Norman castles and the medieval cathedrals, through the Tudors and the Stuarts and the Civil War, and arrives at the revolution that settled, once and for all, that even kings must answer to the law. This series of approximately fifty stories will cover the period from roughly 800 to 1700 AD, 900 years of how the Britain we know today came into being.

A new instalment will be published every week, each one written to be read in a single sitting of fifteen to twenty minutes – long enough for a child to get lost in, short enough for it to stay with them.

Each article stands alone as a piece of storytelling, but together they will form a single, continuous narrative: the story of an island, from its earliest kingdoms to the birth of the modern world.

The first instalment begins with a king hiding in the Somerset marshes in the winter of 878, watching the smoke rise from a burning country, wondering whether everything he has built is already lost.

His name is Alfred, King Alfred, and his story is where England begins.
