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).
Duchy of Aquitaine
Having suppressed a revolt in his new possession, Henry gave it to his son Richard. When Richard died in 1199, it reverted to Eleanor, and on her death five years later, it was absorbed into the English crown and henceforward followed the fortunes of the other English possessions in France, such as Normandy and Anjou, ultimately leading to the Hundred Years' War between the French and English crowns.
