Many English kings had tried to establish rights to the French throne, and many had failed, but this was to change following Henry V’s successful military campaign in France.
The Treaty of Troyes was an agreement between Henry V of England and Charles VI of France. It stated that Henry V and any heirs to the English throne would inherit the throne of France on the death of Charles VI. It was signed on 21 May 1420 in the city of Troyes, France.
As part of the treaty an agreement was made for Henry V to marry Catherine of Valois, daughter of the French king, and they married on 2 June 1420. Henry was then made regent of France, and Dauphin Charles was disinherited.
Henry V and Charles VI died within two months of each other in 1422. Henry’s son, now Henry VI was crowned king of France, however Charles disputed this and gaining support he was crowned Charles VII of France.
Following a military victory by Charles VII, the throne was his, however England and France continued to fight over the French throne for many years.
