The Hundred Years' War (1337 - 1453) was a series of conflicts that, actually, lasted 116 years, between the kingdoms of France and England. It pitted the Kingdom of England against the Valois Capetians for control of the French throne. Each side drew many allies into the fighting.The war had its roots in a dynastic disagreement dating back to the time of William the Conqueror, who became King of England in 1066 while retaining possession of the Duchy of Normandy in France. As the rulers of Normandy and other lands on the continent, the English kings owed feudal homage to the King of France. In 1337, Edward III of England refused to pay homage to Philip VI of France, leading the French King to claim confiscation of Edward's lands in Aquitaine.
