Guyenne

Guyenne then comprised the Bordelais (the old countship of Bordeaux), the Bazadais, part of Périgord, Limousin, Quercy and Rouergue, and the Agenais ceded by Philip III to Edward I in the 1279 Treaty of Amiens.

[2] By the 1360 Treaty of Brétigny, King Edward III of England acquired the full sovereignty of the duchy of Guyenne, together with Aunis, Saintonge, Angoumois, and Poitou.

In 1469, Louis XI gave it in exchange for the territories of Champagne and Brie to his brother Charles, Duke of Berry, after whose death in 1472 it again became part of the royal domain.

[3] The government of Guyenne and Gascony (Guienne et Gascogne), with its capital at Bordeaux, lasted until the end of the Ancien Régime in 1792.

Under the French Revolution, the departments formed from Guyenne proper were those of Gironde, Lot-et-Garonne, Dordogne, Lot, Aveyron and the chief part of Tarn-et-Garonne.
