Treaty of Troyes
To accept the Treaty of Troyes would be a denial of the legitimacy of the Valois. While England was accustomed to change her kings, the French largely adhered to theirs. The treaty was recognized only in English-controlled territories in northern France, and by the allied dukes of Burgundy and Brittany. Henry V died before his sickly father-in-law, Charles VI, leaving the future of the Lancastrian Kingdom of France in the hands of his infant son Henry VI of England, and his brother, John, Duke of Bedford.
