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).
Royal Arms of England
In 1340, following the extinction of the House of Capet, Edward III claimed the French throne. In addition to initiating the Hundred Years' War, Edward III expressed his claim in heraldic form by quartering the royal arms of England with the Arms of France. This quartering continued until 1801, with intervals in 1360–1369 and 1420–1422.
