Duchy of Normandy

The Duchy of Normandy was a significant territory in medieval France, formed in the 10th century. It was originally established when Viking leaders settled in the region, blending Norse and Frankish cultures. The duchy became known for its strong maritime trade and military power. In 1066, William the Conqueror, the Duke of Normandy, famously invaded England, changing the course of English history. The duchy played a crucial role in the feud between France and England, with various dukes and kings vying for control, influencing political dynamics in both nations throughout the Middle Ages.
