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
The Valois kings of France, claiming supremacy over Aquitaine, granted the title of duke to their heirs, the Dauphins, during 1345 and 1415: John II (1345–50), Charles VII (1392?–1401), and Louis (1401–15). French victory was complete with the Battle of Castillon of 1453. England and France nominally remained at war for another 20 years, but England was in no position to continue its campaign, due to its escalating internal conflicts. The Hundred Years' War was formally concluded with the Treaty of Picquigny of 1475. With the end of the Hundred Years' War, Aquitaine returned under direct rule of the king of France and remained in the possession of the king. Only occasionally was the title of "duke of Aquitaine" granted to another member of the dynasty, and then as a purely nominal distinction.
