The Norman rulers were a group of leaders from the region of Normandy in northern France. They gained prominence in the 11th century, particularly after the Norman Conquest of England in 1066, when William the Conqueror claimed the English throne. This event significantly changed the political landscape of England and established a new ruling class. Under the Norman dynasty, the rulers implemented feudalism, which organized society into a hierarchy of lords and vassals. They built impressive stone castles and cathedrals, reflecting their power and influence. The Norman legacy can still be seen today in various aspects of English culture and architecture.
