The House of Normandy was a royal dynasty that originated in the region of Normandy, France. It rose to prominence in the 10th century and is best known for its connection to the Norman Conquest of England in 1066, when William the Conqueror, the Duke of Normandy, claimed the English throne. The house produced several notable monarchs, including Henry I and Stephen of Blois. The Norman kings played a significant role in shaping medieval England, influencing its culture, governance, and land ownership. The dynasty eventually merged with the Plantagenets through marriage, marking the end of the direct line of the Normans.
