Historical region, southwestern France. It was roughly equivalent to Aquitania, the Roman division of southwestern Gaul, which consisted of the area between the Pyrenees Mountains and the Garonne River. Conquered by Clovis in AD 507, it was later made a subkingdom by Charlemagne in the 8th century. After the Carolingian decline, it became a powerful duchy, which by the 10th century controlled much of France south of the Loire. It passed to the Capetian line when Eleanor of Aquitaine married Louis VII (1137); on her second marriage, to Henry II of England (1152), it passed to the English Plantagenets. The name Guyenne, a corruption of Aquitaine, came into use in the 10th century, and the subsequent history of Aquitaine is merged with that of Gascony and Guyenne
born 1122 died April 1, 1204, Fontevrault, Anjou, Fr. Queen consort of Louis VII of France (1137-80) and Henry II of England (1152-89), the most powerful woman of 12th-century Europe. She inherited the duchy of Aquitaine and married the heir to the French throne. Beautiful, capricious, and strong-willed, she accompanied Louis on the Second Crusade (1147-49), and her conduct aroused his jealousy. The marriage was annulled (1152), and she married Henry Plantagenet, soon to be Henry II; the marriage united England, Normandy, and western France under his rule. She bore Henry five sons, including the future kings Richard I the Lionheart and John Lackland, and three daughters who married into other royal houses. Her court at Poitiers became a centre of culture, fostering the poetry of the troubadours. She may have spurred her sons to revolt against Henry (1173); when the rebellion failed she was captured and confined until his death (1189). She was active in government during the reign of Richard I, ruling during his crusade to the Holy Land and ransoming him from Austria. After Richard died (1199) and John became king, she saved Anjou and Aquitaine for John against French threats, then retired to the monastery at Fontevrault
