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
Henry IV of England died in 1413 and was replaced by his eldest son Henry V. The mental illness of Charles VI of France allowed his power to be exercised by royal princes whose rivalries caused deep divisions in France. Henry V was well aware of these divisions and hoped to exploit them. In 1414 while he held court at Leicester, he received ambassadors from Burgundy. Henry accredited envoys to the French king to make clear his territorial claims in France; he also demanded the hand of Charles VI's youngest daughter Catherine of Valois. The French rejected his demands, leading Henry to prepare for war.
