The major conflict fought in France from 1337 to 1453 is known as the Hundred Years' War. This prolonged series of battles was primarily between the Kingdoms of England and France, stemming from territorial disputes and claims to the French throne. The war saw significant battles, including those at Crécy and Agincourt, but it also included periods of truce and diplomatic negotiations. Ultimately, the war ended with the expulsion of the English from most of France, reinforcing the French monarchy and having a lasting impact on national identities in both England and France.
