It was only a matter of months before William, Duke of the large and powerful duchy of Normandy in France, paid Harold a visit to bring to his remembrance his own claim to the throne. William raised an army of Normans by promising them land and wealth when he came into his rightful kingship. October 14th 1066 he and William fought at the famous battle of Hastings. William and his army of Normans came, saw, and conquered. True to his promise to his fellow warriors, William systematically replaced the English nobility with Norman barons and noblemen who took control of the land, the people, and the government.
