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.
Abbey of Saint-Vigor de Cerisy
In 1337, the dynastic rivalries between the Valois and the kings of England precipitated the country into the Hundred Years War, which plunged the country into misery, aggravated by epidemics of plague. The abbey was fortified and a garrison settled there. In 1418, Richard de Silly, knight and captain of the abbey, was obliged to cede the abbey to the King of England. However, after the victory of the constable de Richemont over the English at Formigny in 1450, Normandy returned definitively to the kingdom of France.
