January
5 January. Edward the Confessor, King of England, dies at Westminster after a long illness. He is buried the next morning in the abbey he spent decades building, just days after its consecration. The question of who should succeed him has no simple answer. Edward had no children.
6 January. Harold Godwinson, Earl of Wessex and the most powerful nobleman in England, is crowned king in Westminster Abbey, possibly within hours of Edward's funeral. The speed is remarkable even by medieval standards. The Anglo-Saxon council of nobles, the Witan, endorses him as king, but Harold knows he is not the only claimant. Across the Channel, Duke William of Normandy believes the throne was promised to him. In Scandinavia, King Harald Hardrada of Norway has his own claim. Harold's crown comes with a target on his head.
Spring
Harold spends the early months of his reign preparing for trouble. He knows William is gathering forces in Normandy and that an invasion fleet is being built. Harold musters the English fleet along the south coast and positions his army to defend against a Channel crossing. It is the largest military mobilisation England has seen in living memory.
Late April. Halley's Comet blazes across the sky, visible for several nights. Across Europe it is read as an omen of catastrophe. In England, Harold's enemies interpret it as God's verdict on a perjured king. The Bayeux Tapestry captures the moment in one of its most famous scenes: men pointing at the sky in alarm, while Harold twists nervously on his throne.
Summer
The summer of 1066 is a long, tense wait. Harold holds his fleet and army on the south coast through June, July and August, watching for William's sails. The problem is that medieval armies cannot be held together indefinitely. The men are farmers and landholders with harvests to bring in, and the fleet's supplies are running low.
8 September. With no sign of William and his supplies exhausted, Harold is forced to disband his coastal army and stand down the fleet. The men go home. The south coast is left undefended. It is the worst possible timing.
September
Mid-September. Harald Hardrada of Norway, allied with Harold's own exiled brother Tostig, sails up the Humber with a fleet of around 300 ships and lands in Yorkshire. The northern earls Edwin and Morcar march to meet him.
20 September. The Battle of Fulford Gate. Hardrada and Tostig crush the northern English army outside York. The city submits and agrees to provide hostages. Hardrada camps at Stamford Bridge, east of York, to await the hostages and collect provisions. He believes the campaign is won.
25 September. Harold, who has force-marched his army roughly 185 miles from London in four days, arrives at Stamford Bridge with no warning. The Vikings are caught completely off guard, many without their armour. The battle is ferocious. Hardrada is killed by an arrow to the throat. Tostig is cut down. The Norwegian army is annihilated. Of the roughly 300 ships that brought them, only 24 are needed to carry the survivors home. It is one of the most decisive battles in English history, and Harold fights it brilliantly.
27 September. Two days after Stamford Bridge, the wind in the Channel changes. William's invasion fleet, which has been waiting at Saint-Valery-sur-Somme for weeks, finally sets sail.
28 September. William lands at Pevensey on the Sussex coast. There is no opposition. Harold's fleet has been stood down. His army is 250 miles away in Yorkshire, battered from Stamford Bridge. William builds a fort, begins ravaging the countryside, and waits.
October
Harold receives news of William's landing while still in the north. He immediately turns his exhausted army around and marches south at extraordinary speed, covering the distance in under a fortnight. He arrives in London around 6 October and pauses briefly to gather reinforcements, though many of his best troops are still straggling south from Yorkshire.
13 October. Harold marches out of London and takes up position on Senlac Ridge, about seven miles north of Hastings, blocking the road to London. He arrives in the evening and deploys his army along the ridge in a dense shield wall.
14 October. The Battle of Hastings. The battle begins at around nine in the morning and lasts all day, an unusually long engagement by medieval standards. William attacks uphill with archers, infantry and cavalry. The English shield wall holds firm for hours. The Normans attempt feigned retreats to lure the English off the ridge, with mixed success. A rumour spreads that William has been killed. He rides along the line, lifts his helmet to show his face, and rallies his troops. By late afternoon the English line is thinning. Harold's brothers Leofwine and Gyrth are dead. As dusk approaches, Harold himself is killed. The circumstances of his death are disputed to this day, the Bayeux Tapestry shows a figure with an arrow in or near his eye and another being struck down by a mounted knight, but which is Harold, or whether both are, remains uncertain. With the king dead, the English army breaks and flees into the gathering darkness.
A sharp and forensically argued book that takes the familiar story of 14 October 1066 apart and reassembles it from the ground up. Ian Pusey examines the landscape, the sources, and the decisions that shaped the outcome, asking whether the standard account of the battle holds up to scrutiny. Essential reading for anyone who has just worked through this timeline and wants to go further.

William does not march directly on London. He sweeps through Kent, takes Dover, then circles around London, crossing the Thames at Wallingford and approaching the city from the north-west. The English leadership, already fractured, collapses. Edgar the Aetheling, the last male of the royal house, is briefly proclaimed king but never crowned. The leading English nobles and churchmen submit to William at Berkhamsted.
25 December 1066. William is crowned King of England in Westminster Abbey on Christmas Day. During the ceremony, the shouts of acclamation from inside the abbey are misheard by the Norman guards outside, who think a riot has broken out. They set fire to surrounding buildings. The congregation panics. William, according to one account, is left trembling at the altar. It is a fitting end to the most violent and chaotic year in English history.
The Aftermath
The Conquest was not completed in a single year. English resistance continued for years, particularly in the north, where William's response, the Harrying of the North in 1069-70, devastated Yorkshire so thoroughly that the Domesday Book, compiled twenty years later, still records vast areas as waste. But 1066 itself, a single year containing three pitched battles, two foreign invasions, three kings and the end of Anglo-Saxon England, remains the most consequential twelve months in English history. Every English monarch since has descended from William. The language, the law, the architecture, the very idea of what England is, all trace back to this year.
