Hundred Years' War
The Hundred Years' War was a series of conflicts waged from 1337 to 1453 by the House of Plantagenet, rulers of the Kingdom of England, against the French House of Valois, over the right to rule the Kingdom of France. Each side drew many allies into the war. It was one of the most notable conflicts of the Middle Ages, in which five generations of kings from two rival dynasties fought for the throne of the largest kingdom in Western Europe. The war marked both the height of chivalry and its subsequent decline, and the development of strong national identities in both countries.
Battle of Auberoche
The status of the English king's French fiefs was a major source of conflict between the two monarchies throughout the Middle Ages. French monarchs systematically sought to check the growth of English power, stripping away lands as the opportunity arose. Towards the end of 1336, following a series of disagreements between Philip VI of France () and Edward III of England (), Philip decided that war was the only way to drive the English out for good. On 24 May 1337 Philip's Great Council in Paris agreed that the Duchy of Aquitaine, effectively Gascony, should be taken back into Philip's hands on the grounds that Edward was in breach of his obligations as a vassal. This marked the start of the Hundred Years' War, which was to last one hundred and sixteen years.
