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 Days Offensive
The Hundred Days Offensive (8 August to 11 November 1918) was an Allied offensive which ended the First World War. Beginning with the Battle of Amiens (8–12 August) on the Western Front, the Allies pushed Central Powers back after their gains from the Spring Offensive. The Germans eventually retreated to the Hindenburg Line, culminating in the Armistice of 11 November 1918. The term "Hundred Days Offensive" does not refer to a battle or strategy, but rather the rapid series of Allied victories against which the German armies had no reply.
