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.
Chevauchée
The chevauchée has gained recognition for its use during the Hundred Years' War between the Kingdom of England and the Kingdom of France. It was not a new tactic and had been used many times before; for example, William the Conqueror had used the tactic before the Battle of Hastings to encourage Harold to engage in a battle. The difference was that during the Hundred Years' War the tactic was used more frequently, on a larger scale and more systematically than before.
