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.
Robert de Crull
The years of Crull's service as administrator of the navy (1359–78) were difficult ones for England. Edward III had achieved a succession of victories in France enabling him to secure great possessions. This had been another chapter in the ongoing Hundred Years War. His claim to the French throne seemed to be about to be realised. In 1359, he began a campaign to complete that undertaking. However, after a number of battles well into 1360 the outcome was still in doubt, and Edward was forced to accept the Treaty of Bretigny wherein he renounced his claim to the French throne so that he could secure full sovereignty of the possessions he had in France.
