The Hundred Years' War was a series of conflicts fought between England and France from 1337 to 1453. The war was primarily over territorial disputes and claims to the French throne. It included famous battles such as Crecy and Agincourt, and saw the rise of notable figures like Joan of Arc. The war had significant impacts on both nations, leading to changes in military tactics and the development of national identities. By the end of the conflict, France emerged victorious, reclaiming most of its territories, while England faced internal strife, eventually leading to the Wars of the Roses.
