In the 13th century, as a result of the conquests of
Philip II,
Louis VIII and
Louis IX, Guyenne was confined within the narrower limits fixed by the
1259 Treaty of Paris and became distinct from Aquitaine. 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. Still united with Gascony, it formed a duchy extending from the
Charente River to the
Pyrenees mountains. This duchy was held as a
fief on the terms of
homage to the French kings and, both
in 1296 and 1324, it was confiscated by the kings of France on the ground that there had been a failure in the
feudal duties. The government of Guyenne and Gascony (''''), with its capital at Bordeaux, lasted until the end of the 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. ==See also==
