The Hundred Years' War (French: Guerre de Cent Ans; 1337–1453 [116 years]) was a conflict between the kingdoms of England and France and a civil war in France during the late Middle Ages. It emerged from feudal disputes over the Duchy of Aquitaine and was triggered by a claim to the French throne made by Edward III of England. The war grew into a broader military, economic, and political struggle involving factions from across Western Europe, fuelled by emerging nationalism on both sides.
