William the Conqueror

William, Duke of Normandy, defeated King Harold II of England at Hastings. Harold was killed in battle. William then marched to London and was crowned King of England on Christmas Day 1066, beginning Norman rule in England.

William led a brutal military campaign to suppress rebellions in northern England. His forces systematically destroyed crops, livestock, and settlements across Yorkshire and Northumbria. The devastation caused a famine that killed tens of thousands and depopulated large areas.

William convened a council of Norman barons and bishops at Lillebonne to assert royal authority over the Church in Normandy. The council issued decrees regulating ecclesiastical jurisdiction and property, strengthening ducal control.

William ordered a comprehensive survey of landholdings and resources in England. The resulting Domesday Book recorded ownership, value, and population for tax assessment. It became the most detailed administrative record in medieval Europe.
