William I of England
William I of England (1027 – 9 September 1087), better known as William the Conqueror, was Duke of Normandy from 1035 and King of England from 1066 to his death. To claim the English crown, William invaded England in 1066, leading an army of Normans to victory over the Anglo-Saxon forces of Harold Godwinson (who died in the conflict) at the Battle of Hastings, and suppressed subsequent English revolts in what has become known as the Norman Conquest. His reign, which brought Norman culture to England, had an enormous impact on the subsequent course of England in the Middle Ages. In addition to political changes, his reign also saw changes to English law, a programme of building and fortification, changes to the vocabulary of the English language, and the introduction of continental European feudalism into England.
