The Hundred Years' War was a conflict that took place between the years 1337 and 1453, primarily between England and France. Although the name suggests that the war lasted for a century, it was actually a series of intermittent conflicts involving different kingdoms and dynasties. The war originated due to various territorial, economic, and political disputes between the kingdoms of England and France. One of the main triggers was the claim to the French throne by Edward III of England, who argued to be the legitimate heir through his mother. Throughout the war, significant events and battles occurred, such as the Battle of Crécy, the Battle of Poitiers, and the Battle of Agincourt, in which English armies achieved important victories thanks to their long-range archer tactics. However, as the war progressed, France managed to regain ground, and eventually, French persistence and resistance prevailed. The conflict ended with the signing of the Treaty of Picquigny in 1475, which recognized the independence of France and put an end to the war. The Hundred Years' War had a significant impact on both countries and is considered an important transitional period in European history. Additionally, the conflict also influenced the evolution of military strategies, technology, and diplomacy at the time.
