Timeline of the Hundred Years' War
This is a timeline of the Hundred Years' War between England and France from 1337 to 1453 as well as some of the events leading up to the war. (The Hundred Years' War actually spanned for 116 years.)
The Battle of Castillon is generally considered the end of the Hundred Years' War as Henry VI's insanity and the Wars of the Roses left England in no position to wage war in France. However Calais remained an English possession until 1558 and the title of King of France was not omitted from the English royal style until 1 January 1801 ( after the Battle of Castillon).

Seven years previously, King Philip VI of France attempted to confiscate the Duchy of Guyenne (also referred to as Aquitaine) from Edward III – an event that traditionally marks the beginning of the Hundred Years' War – after which Edward used military force, diplomacy and marital links to strengthen his claim to the French throne. In the Duchy of Brittany succession dispute, he supported John of Montfort since a close alliance to the English crown with Brittany would give Edward access to the port of Brest for use by English troops. When Montfort was captured, his wife, Joanna of Flanders, took over the campaign and, during the siege of Rennes, received military support from Edward. In return, she promised her son John (later John IV, Duke of Brittany) to one of his daughters.
