The French nobility selected Philip of Valois as king over Edward III of England, sparking a succession crisis. The Hundred Years' War consisted of sporadic battles and raids between the relative strengths of France and England. A major turning point was the victory at Agincourt in 1415 that gave the English control of northern France, culminating in the Treaty of Troyes that declared Henry V heir to the French throne. However, Joan of Arc's military victories for Charles VII starting in 1429 helped the French begin reconquering territory, and the war ended in 1453 with England losing its remaining continental possessions.
