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 Gerberoy
In spring 1435 the Hundred Years' War, after a few years of relative calm began to come back into a hot phase. The English armies were operating from northern France and Aquitaine. They also controlled Paris, Saint-Denis and the whole of Normandy. Nevertheless, the situation in the occupied territories for the English during the last decades had become more difficult. Although Joan of Arc was captured in 1430 and executed in 1431, it seemed to be more difficult to rule France and enforce the Treaty of Troyes.
