Dukes of Normandy Timeline 911-1259

Dukes of Normandy - William II

This timeline details all Dukes of Normandy from 911 to 1259.

In 911 the Viking Rollo was granted Normandy by the Treaty of Saint-Clair-sur-Epte following the siege of Chatres. Although all rulers of Normandy are generally referred to as Duke, the first rulers actually used the title Count. The title Duke was first used by Richard II around 1006. Normandy remained a self-governing entity until it was assimilated into France by King Philip II of France. It was officially ceded by King Henry III in 1259.
