Chivalry and Betrayal: The Hundred Years' War
In 1435 Bedford died and sworn enemies Charles VII and Phillip, Duke of Burgundy joined forces to get the English out and with Henry VI reluctance to wage war and to maintain peace by marrying Margaret of Anjou. Charles had no intention of peace and used cannon and sieges to retake France and Normandy culminating in the defeat of the English at the Battle of Castillon in the last English territory of Gascony ending the hundred years war.
History of France
It has been argued that the difficult conditions the French population suffered during the Hundred Years' War awakened French nationalism, a nationalism represented by Joan of Arc (1412–1431). Although this is debatable, the Hundred Years' War is remembered more as a Franco-English war than as a succession of feudal struggles. During this war, France evolved politically and militarily.
