The war fought between England and France from 1337 to 1453 is known as the Hundred Years' War. This protracted conflict originated from disputes over territorial claims and the right to the French throne. The war was characterized by several significant battles, including Agincourt and Crécy, and saw the rise of national identities in both England and France. It ultimately ended with the expulsion of the English from most of France, solidifying the French monarchy’s power. The Hundred Years' War had lasting implications for both countries and shaped the course of medieval European history.
