From 1066 until 1204, as a result of the Norman conquest of England, the dukes of Normandy were usually also kings of England, the only exceptions being Dukes Robert Curthose (1087–1106), Geoffrey Plantagenet (1144–1150) and Henry II (1150-1152), who became king of England in 1152.

In 1202, Philip II of France declared Normandy forfeit to him and seized it by force of arms in 1204. It remained disputed territory until the Treaty of Paris of 1259, when the English sovereign ceded his claim except for the Channel Islands; i.e., the Bailiwicks of Guernsey and Jersey, and their dependencies (including Sark).

In the Kingdom of France, the duchy was occasionally set apart as an appanage to be ruled by a member of the royal family. After 1469, however, it was permanently united to the royal domain, although the title was occasionally conferred as an honorific upon junior members of the royal family. The last French duke of Normandy in this sense was Louis-Charles, duke from 1785 to 1789.

The title "Duke of Normandy" continues to be used in an informal manner in the Channel Islands, to refer to the monarch of the United Kingdom.
