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 Lunalonge
Following a series of disagreements between Philip VI of France and Edward III of England, on 24 May 1337 Philip's Great Council in Paris agreed that the Duchy of Aquitaine, which included all of Gascony, should be taken back into the 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. Although Gascony was the cause of the war, Edward was able to spare few resources for it and up to 1349 whenever an English army campaigned on the continent it operated in northern France. In most campaigning seasons the Gascons had had to rely on their own resources and had been hard pressed by the French.
