Gregory IX. was quite content thus to close the war which Innocent had commenced twenty years before. Already, in March, 1228, he wrote to Louis IX., urging him to make peace according to the judgment of the legate, Cardinal Romano, who had full powers in the premises, and it was in the name of the legate that the first overtures were made to Raymond through the Abbot of Grandselve. That the marriage was the pivot upon which from the beginning the negotiations turned is shown by another letter of June 25, authorizing Romano to dispense with the impediment of consanguinity if the union between Jeanne and one of the king's brothers would lead to peace. Another epistle of October 21, announcing to all the prelates of France that he had renewed the indulgences for a crusade against the Albigenses, would seem to show that the terms offered to Raymond were hard of acceptance, and that renewed pressure on him was necessary. This was enforced by extensive devastations in his territories, and in December, 1228, he gave the abbot full power to assent to whatever might be agreed upon by Thibaut of Champagne, who acted as mediator for him. A conference was held at Meaux, where we find the consuls of Toulouse also represented, and preliminaries were signed in January, 1229. Finally, on Holy Thursday, April 12, 1229, the long war came to an end. Before the portal of Nôtre Dame de Paris Raymond humbly approached the legate and begged for reconciliation to the Church; barefooted and in his shirt he was conducted to the altar as a penitent, received absolution in the presence of the dignitaries of Church and State, and his followers were relieved from excommunication. After this he constituted himself a prisoner in the Louvre until his daughter and five of his castles should be in the hands of the king, and five hundred toises of the walls of Toulouse should be demolished.[180]
