France
The kingdom of France, populated up until the Black Death of 1348-9 by 12-16 millions souls and including up to the Treaty of Brétigny (1360) the Ile-de-France together with the apanages of Normandy, Anjou, Bourbon, Champagne, Valois, Auvergne and Languedoc, plus a number of important fiefs such as the counties of Blois, Nevers and Foix, and (from 1349) Montpellier and the Dauphiné; diminished from 1354 by the growing activity and influence in the Cotentin and other parts of Normandy of the king of Navarre, Charles of Evreux, and by English conquests resulting in an enlarged duchy of Guyenne (essentially Gascony; will become the principality of Aquitaine) stretching from the borders of the great and at times pro-English duchy of Brittany to the Pyrenees (save for the neutral county of Béarn) and eastwards to embrace the Poitou, Limousin and Rouergue (on the border with the Languedoc); Ponthieu and Guines are also in English hands. The French re-conquest under Charles V and Du Guesclin progressively drives the English from the realm, leaving them (by 1370-80) the ports of Calais, Cherbourg, Brest, Bordeaux and Bayonne, and a much-reduced Aquitaine. Brittany returns to French allegiance from 1365 onwards (Treaty of Guérande).
