The Hundred Years War

"The Hundred Years' War was a series of conflicts waged from 1337 to 1453 between the Kingdom of England and the Kingdom of France for control of the French throne. Many allies of both sides were also drawn into the conflict. 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."--Wikipedia.
