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).
Hundred Years' War
Henry IV of England died in 1413 and was replaced by his eldest son Henry V. The mental illness of Charles VI of France allowed his power to be exercised by royal princes whose rivalries caused deep divisions in France. Henry V was well aware of these divisions and hoped to exploit them. In 1414 while he held court at Leicester, he received ambassadors from Burgundy. Henry accredited envoys to the French king to make clear his territorial claims in France; he also demanded the hand of Charles VI's youngest daughter Catherine of Valois. The French rejected his demands, leading Henry to prepare for war.
