Background

The Anglo-Saxon Kingdom of England was the most centralized state in 11th-century Western Europe — wealthy, administratively coherent, and protected by an effective royal taxation and military system established by the late-9th-century reforms of Alfred the Great and his successors. It was, however, politically unstable in 1066. The childless King Edward the Confessor (reigned 1042–1066) had no clear successor; at least three substantial claimants existed at his death on 5 January 1066.

Harold Godwinson, the most powerful English earl and Edward’s brother-in-law, was crowned the next day at Westminster. His claim was supported by the Witan (the Anglo-Saxon council of senior nobles) but was disputed by:

  • William, Duke of Normandy, who claimed Edward had previously promised him the crown and that Harold had personally sworn an oath of fealty to William during a visit to Normandy in 1064 or 1065.
  • Harald Hardrada, King of Norway, who claimed the English throne through a 1038 agreement between his predecessor Magnus the Good and the earlier Danish king of England, Harthacanute.

Both rivals invaded in 1066.

The two invasions

Harald Hardrada landed in northern England in early September 1066 with approximately 9,000 troops, supported by Harold Godwinson’s exiled brother Tostig. The Norwegian army was destroyed at the Battle of Stamford Bridge near York on 25 September 1066 by Harold Godwinson’s English army. Hardrada and Tostig were killed. The end of Stamford Bridge is conventionally treated as the end of the Viking Age.

Harold then learned that William of Normandy had landed on the south coast of England on 28 September 1066 with approximately 7,000 troops. Harold marched his exhausted army south at forced-march speed (approximately 250 miles in nine days) and met the Normans at the village of Senlac (now Battle, Sussex), about seven miles north of Hastings, on the morning of 14 October 1066.

The Battle of Hastings

The battle lasted approximately nine hours — unusual for medieval engagements. The English fought a defensive shield-wall formation on a low ridge; the Norman army combined heavy cavalry, archers, and infantry in a more flexible attacking force. Several Norman cavalry charges failed against the English wall. The decisive moment came when feigned Norman retreats drew the English right flank off the ridge and into the open. Norman archers shooting upward at the remaining English position eventually broke the line. Harold was killed near the end of the day — the famous arrow-in-the-eye image from the Bayeux Tapestry is iconic but probably depicts only one of several wounds.

Anglo-Saxon casualties were approximately 4,000 including the king, his two surviving brothers (Gyrth and Leofwine), and most of the senior English nobility present. Norman casualties were probably 2,000.

The conquest

The battle did not end the war. William marched on London via a circuitous route — Dover, Canterbury, the Thames at Wallingford — accepting submissions from English bishops and major towns. He was crowned at Westminster Abbey on Christmas Day 1066. Resistance continued in pockets across England for several years, culminating in the Harrying of the North in winter 1069–1070, in which William systematically destroyed the agricultural infrastructure and food supplies of Yorkshire and adjacent counties in response to repeated revolts. The famine that followed killed by some estimates 100,000 people.

By the early 1070s English political resistance was effectively over. William instituted the most thorough replacement of a ruling class in medieval European history: by 1086, approximately 95% of the English landed elite had been replaced by Normans and other continental adventurers. The English language was demoted from the language of court and government; Norman French would be the language of English government for the next 300 years, with substantial linguistic effects on English vocabulary that are still visible today.

The Domesday Book

In 1086 William commissioned a comprehensive land-survey of England — the Domesday Book — recording every village, every manor, every landholder, every plow, and every assessable property in the kingdom. The two surviving volumes (Great Domesday and Little Domesday) are the most detailed administrative survey of any 11th-century state anywhere in the world. They remain a foundational source for medieval economic history and have substantial legal weight in English property law — modern Crown rights to certain royal forests are still adjudicated against Domesday entries.

Legacy

The Norman Conquest produced the dynastic line that became the Plantagenets (from 1154), substantially reformed English government and law toward the Anglo-Norman continental model, and produced the linguistic and cultural fusion that defines modern English. Modern English vocabulary is approximately 30% Norman-French; modern English law combines Anglo-Saxon common-law tradition with Norman-French administrative practice. The royal continuity from William the Conqueror (1066) to Charles III (2022) is one of the longer monarchical traditions in continuous existence.

The Battle of Hastings site is now a National Heritage site administered by English Heritage. The abbey William founded on the battlefield to atone for the dead was a working monastery for nearly five centuries before its dissolution by Henry VIII in 1538.
