query: From what years did the Hundred Years War last?
passage: 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.
passage: Second Hundred Years' War
After William III, the opposition of France and Britain shifted from religion to economy and trade: the two nations vied for colonial domination in the Americas and Asia. The Seven Years' War was one of the greatest and most decisive conflicts. France's alliance and backing of the colonists in the American Revolutionary War against Britain was successful in undermining British colonial hegemony in North America, but in turn debts from that conflict sowed the economic seeds of France's own revolution shortly thereafter.
