Duchy of Aquitaine

The Duchy of Aquitaine (Occitan: Ducat d'Aquitània, IPA: [dyˈkad dakiˈtaɲɔ]; French: Duché d'Aquitaine, IPA: [dyʃe dakitɛn]) was a historical fiefdom in western, central, and southern areas of present-day France to the south of the river Loire, although its extent, as well as its name, fluctuated greatly over the centuries, at times comprising much of what is now southwestern France (Gascony) and central France.

It originated in the 7th century as a duchy of Francia, ultimately a recreation of the Roman provinces of Aquitania Prima and Secunda. As a duchy, it broke up after the conquest of the independent Aquitanian duchy of Waiofar, going on to become a sub-kingdom within the Carolingian Empire. It was then absorbed by West Francia after the 843 partition of Verdun and soon reappeared as a duchy under it. In 1153, an enlarged Aquitaine pledged loyalty to the Angevin kings of England. As a result, a rivalry emerged between the French monarchs and the Angevins over control of the latter's territorial possessions in France. By the mid-13th century, only Gascony remained in Angevin hands. The Hundred Years' War finally saw the kingdom of France gain full control over Aquitaine in the 1450s, with much of its territory directly incorporated into the French royal domain itself.
