The term Angevin Empire is a modern term describing the collection of states once ruled by the Angevin Plantagenet dynasty.

Court is generally held at Angers and Chinon.

The Plantagenets rule over an area stretching from the Pyrenees to Ireland during the 12th and early 13th centuries, located north of the kingdoms of Navarre and Aragon.

This "empire" extends over roughly half of medieval France, all of England, and some of Ireland.

However, despite the extent of Plantagenet rule, they are defeated by the King of France, Philip II Augustus of the House of Capet, which leaves the empire split in two, having lost the provinces of Normandy and Anjou.

This defeat, after which the ruling Plantagenets retain their English territories and the French province of Gascony, sets the scene for the Saintonge and the Hundred Years' War.
