Aquitaine

Duchy in southwest France, ranging from the Pyrenees to the Loire and including Gascony. It passed to the Angevins when Henry of Anjou married Eleanor of Aquitaine in 1152, and to England when he became Henry II in 1154. From 1204 the French crown possessed Aquitaine, but Gascony was not regained until the end of the Hundred Years War in 1453.
