A historical region of west-central France bordering on the Bay of Biscay. A part of the Roman province of Aquitania, it fell to the Visigoths (A.D. 418) and the Franks (507) and was frequently contested by France and England until the end of the Hundred Years' War, when it was incorporated into the French crown lands.
