Philip III was the Duke of Burgundy at the time that Louis came to the throne, and was keen to initiate a Crusade to the Holy Lands. However, he needed funds to organize such an enterprise. Louis XI gave him 400,000 gold crowns for the Crusade in exchange for a number of territories, including Picardy and Amiens. However, Philip's son, the future Charles I, Duke of Burgundy (known as the Count of Charolais at the time of Louis's accession) was angry about this transaction, feeling that he was being deprived of his inheritance. He joined a rebellion called the League of the Public Weal, led by Louis's brother Charles, the Duke of Berry. Although the rebels were largely unsuccessful in battle, Louis had no better luck. Louis XI fought an indecisive battle against the rebels at Montlhéry and was forced to grant an unfavourable peace as a matter of political expediency.
