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.
Hundred Years' War
In 1366 there was a civil war of succession in Castile (part of modern Spain). The forces of the ruler Peter of Castile were pitched against those of his half-brother Henry of Trastámara. The English crown supported Peter; the French supported Henry. French forces were led by Bertrand du Guesclin, a Breton, who rose from relatively humble beginnings to prominence as one of France's war leaders. Charles V provided a force of 12,000, with du Guesclin at their head, to support Trastámara in his invasion of Castile.
