William the Conqueror

William I, usually known as William the Conqueror and sometimes William the Bastard, was the first Norman King of England, reigning from 1066 until his death in 1087. Descended from Viking raiders, he had been Duke of Normandy since 1035 under the title of William II. After a long struggle to establish his power, by 1060 his hold on Normandy was secure, and he launched the Norman conquest of England in 1066.
