Treaty of Troyes
The Regency Council tried to install Henry VI as the King of France, as provided by the Treaty of Troyes signed by his father, and led English forces to take over areas of France. It appeared they might succeed due to the poor political position of the son of Charles VI, who had claimed to be the rightful king as Charles VII of France. However, in 1429, Joan of Arc began a military effort to prevent the English from gaining control of France. The French forces regained control of French territory.
