Hundred Years' War

Series of conflicts between England and France in 1337–1453. Its causes were the French claim (as their fief) to Gascony in southwest France, held by the English kings, and medieval trade rivalries in Flanders. Medieval England and France had a long history of war before 1337, and the Hundred Years' War has sometimes been interpreted as merely an intensification of these struggles. It was caused by fears of French intervention in Scotland, which the English were trying to subdue, and by the claim of England's Edward III (through his mother Isabella, daughter of Philip IV of France) to the crown of France.
