The Norman Conquest refers to the invasion and subsequent occupation of England by the Normans in 1066. Led by William the Conqueror, the Duke of Normandy, this event began with the famous Battle of Hastings, where William defeated King Harold II. This marked a significant shift in English history, as it introduced Norman culture, language, and governance. Following the conquest, the Normans established a feudal system, redistributing land to their supporters. They built castles and cathedrals, which transformed the English landscape. The conquest also led to the blending of Anglo-Saxon and Norman traditions, shaping the future of England and its society.
