His son, Raymond VII., continued the war for eighteen months longer, with enough of popular favor and of success to make his enemies despair of recovering their advantages; and, on the 14th of January, 1224, Amaury de Montfort, after having concluded with the Counts of Toulouse and Foix a treaty which seemed to have only a provisional character, "went forth," says the History of Languedoc, "with all the French from Carcassonne, and left forever the country which his house had possessed for nearly fourteen years." Scarcely had he arrived at the court of Louis VIII., who had just succeeded his father, Philip Augustus, when he ceded to the King of France his rights over the domains which the crusaders had conquered by a deed conceived in these terms: "Know that we give up to our Lord Louis, the illustrious King of the French, and to his heirs forever, to dispose of according to their pleasure, all the privileges and gifts that the Roman Church did grant unto our father Simon of pious memory, in respect of the countship of Toulouse and other districts in Albigeois; supposing that the pope do accomplish all the demands made to him by the king through the Archbishop of Bourges, and the Bishops of Langres and Chartres; else, be it known for certain that we cede not to any one aught of all these domains." Whilst this cruel war lasted Philip Augustus would not take any part in it.

Not that he had any leaning towards the Albigensian heretics on the score of creed or religious liberty; but his sense of justice and moderation was shocked at the violence employed against them, and he had a repugnance to the idea of taking part in the devastation of the beautiful southern provinces.

He took it ill, moreover, that the pope should arrogate to himself the right of despoiling of their dominions, on the ground of heresy, princes who were vassals of the King of France; and, without offering any formal opposition, he had no mind to give his assent thereto.

When Innocent III.

called upon him to co-operate in the crusade, Philip answered, "that he had at his flanks two huge and terrible lions, the Emperor Otho, and King John of England, who were working with all their might to bring trouble upon the kingdom of France; that, consequently, he had no inclination at all to leave France, or even to send his son; but it seemed to him enough, for the present, if he allowed his barons to march against the disturbers of peace and of the faith in the province of Narbonne." In 1213, when Simon de Montfort had gained the battle of Muret, Philip allowed Prince Louis to go and look on when possession was taken of Toulouse by the crusaders; but when Louis came back and reported to his father, "in the presence of the princes and barons who were, for the most part, relatives and allies of Count Raymond, the great havoc committed by Count Simon in the city after surrender, the king withdrew to his apartments without any ado beyond saying to those present, 'Sirs, I have yet hope that before very long Count de Montfort and his brother Guy will die at their work, for God is just, and will suffer these counts to perish thereat, because their quarrel is unjust.'" Nevertheless, at a little later period, when the crusade was at its greatest heat, Philip, on the pope's repeated entreaty, authorized his son to take part in it with such lords as might be willing to accompany him; but he ordered that the expedition should not start before the spring, and, on the occurrence of some fresh incident, he had it further put off until the following year.
