イザボー・ド・バヴィエール
In 1285, when Philip the Fair united Champagne to the royal domain, the town kept a number of its traditional privileges. John the Fearless, Duke of Burgundy and ally of the English, in 1417 worked to have Troyes designated as the capital of France. He came to an understanding with Isabeau of Bavaria, wife of Charles VI of France, that a court, council, and parlement with comptroller's offices should be established at Troyes.
