Guyenne was a general region with a variable shape and dimension according to the times, located in the southwest of France. Its name comes from a gradual evolution of the word Aquitaine. The form Guyenne was the popular name used during the 12th and 13th centuries, while Aquitaine remained the more archaic and cultivated term. The capital was Bordeaux. The region later designated the bulk of the territories held by the King of England after the treaty of Paris (1259), containing the Limousin, Perigord, Quercy, Rouergue and Agenais provinces, as well as parts of Saintonge and Gascogne.
