William the Conqueror (c. 1027-1087 CE), also known as William, Duke of Normandy and William the Bastard, led the Norman Conquest of England in 1066 CE when he defeated and killed his rival Harold Godwinson at the Battle of Hastings. Crowned King William I of England on Christmas Day 1066 CE, William would only secure his new realm after five years of hard battles against rebels and foreign invaders. Continuing to reign over Normandy, William's policies of land redistribution amongst the Norman elite ensured the history of both England and France would be inseparable in the following centuries. An accomplished diplomat, gifted military commander, and ruthless overlord, William died of natural causes in 1087 CE at Caen, Normandy where his tomb still lies.
