Despite de Montfort’s apparent failure his work was decisive. The eight years during which he had maintained himself in Languedoc had not only seen many “Frenchmen” assigned to lands there, they had also seen the moral and political prestige of the southern nobles damaged beyond repair. Toulouse had definitely lost any chance she may have had of rallying the south about her to make head against Paris. Languedoc with her wealth, her culture, and her indifference to the moral unity of Europe, was destined to go under. The great tolerant southern houses were to be swallowed up by the “most Christian” kings of France, who represented the new, vague, but enormous idea of the nation. De Montfort, dead and apparently beaten, had changed the course of history.
The next six years of the Crusade (1218-1224) saw only small wars. They are marked by a single brief and inconclusive campaign, commanded by Louis of France.
The permanent effect of de Montfort’s work did not at first appear. His son Amaury could not fill his place. Philip Augustus promptly permitted Prince Louis to lead another crusading army, with Cardinal Bertrand, the new papal legate, at his side. At Marmande a massacre was achieved fit to rejoice the heart of any mediæval Crusader, but Toulouse successfully resisted another siege, and the army returned home having accomplished nothing. In fact the desultory fighting which went on after its departure ran somewhat in favour of Raymond. Amaury’s strength was mainly in his possession of Carcassonne, on account of its great natural and artificial strength under the conditions of the time, together with its powerful strategic position commanding the highway between the Atlantic and the Mediterranean. But Simon’s son had so little of the ability of his father that he could not prevent Raymond from winning back, bit by bit, much of his old domain. In 1220 Raymond retook Lavaur and slaughtered every man in it except a handful who escaped by swimming down the Agout. The Crusaders had no monopoly of massacre.
Meanwhile Pope Honorius tried every means at his command to push matters, but without success. A new legate, Conrad of Porto by name, set up a military order patterned after the Templars and Hospitallers under the name of “Knights of the Faith of Jesus Christ,” but the new foundation achieved little. In the following year Honorius published a sentence of excommunication and exhereditation against the entire Toulousain House, and raised enough money to set on foot another expedition under Prince Louis. But the Prince turned his army against La Rochelle and took that city from Henry III of England, so that the net result of the Pope’s effort to settle Languedocian affairs was just nothing.
Early in 1222, four years after his father’s death, Amaury de Montfort recognized his position as hopeless and offered all that he possessed or claimed in Languedoc to Philip Augustus. This brought on a year full of diplomacy. Amaury urged Honorius to support his action, and the Pope did so, pointing out the deplorable state of religion in Languedoc, where heresy was openly preached and seemed ineradicable. Philip refused, the obstinate caution of the Capets strong in him. Even the offer of a twentieth of the entire income of the Church in France together with all manner of indulgences did not tempt him. Next Amaury made his offer to Thibaut, the powerful Count of Champagne, but again King Philip blocked matters by refusing to exempt Thibaut from service to the Crown in case of a break with Henry of England. In August Raymond died. His son, succeeding him under the title of Raymond VII, promptly wrote to Philip Augustus to ask his suzerain’s help towards the removal of the Pope’s sentence of excommunication and exhereditation against himself. In December, Amaury repeated his offer to the King, and again the King refused.
The confused and indecisive negotiations of 1222 had at least the result of convincing both the new legate and the King of France that Languedoc must be stabilized, and that promptly. The legate saw that heresy was again on the increase, favoured by the confusion born of the long war. The King felt himself near his end—he was suffering from continual fevers—and he feared that after his own death Louis, with his amiable character and weak health, would find himself drawn into the Languedocian business by the clergy and would die too of the fatigue of it, so that the kingdom would be left in the hands of a woman, Louis’ wife, and of an infant, who was to be St. Louis. Accordingly, when the legate called a council at Sens for the purpose of reconciling Amaury and Raymond VII, Philip asked and obtained a change of meeting place to Paris in order that he himself might be present. He was in the provinces, down with another attack of fever, but felt so deeply the need of a definite settlement that he risked the fatigues of the journey, and died on the way. True to his policy of supporting the de Montforts, but cautiously and without identifying himself with their cause, in his will he left Amaury thirty thousand livres.
Within a few months after Philip’s death, the first of the events his wisdom had foreseen actually came about. Amaury’s financial position had become so bad that in January 1224 he patched up a provisional treaty with Toulouse and Foix, used most of Philip’s legacy to pay off his garrisons, and definitely evacuated Languedoc. The Archbishop of Bourges, together with the Bishops of Langres and Chartres, asked Louis to grant him the reversion of the office of Constable of France, and, with this understanding, for the third time he offered his Languedocian possessions and claims to the French Crown. In February the offer was accepted.
With the acceptance of Amaury’s offer by the French Crown begins the last or monarchical phase of the Crusade, which lasts three years (1224-1227). In it the small war continues—varied by a single major operation, a second campaign under Louis VIII, the amiable son of the wise and crafty Philip Augustus, which operation fails. Despite this military failure, the war ends in a political decision against the House of Toulouse.
The citizens of Narbonne (royalist like all townsmen because of the internal peace and order the Crown stood for) were promptly assured by a letter from the King that he would lead a Crusade which should march three weeks after Easter. In dealing with the Pope, Louis made conditions. Rome was to give him one of his own prelates (the Archbishop of Bourges) for legate instead of the Italian Cardinal Bertrand of Porto, indulgences were to be the same as for a Crusade to Palestine, any of his vassals who might refuse service were to be excommunicated, and Roman diplomacy was to do its utmost to assure him peace with all other possible foreign enemies. Finally, the Church was to give him twenty thousand livres of Paris per year out of its revenues during the Crusade, which was to begin and end when Louis chose. It was a formidable list, but the Church could hardly find any conditions too hard.
At this point matters were held up by another of the innumerable shifts of purpose in the Roman Curia. Henry III of England was Raymond’s kinsman. Moreover, Bordeaux and all the lands still left to the Plantagenet in Aquitaine would be dangerously isolated should the county of Toulouse become French Crown land. Accordingly, English influence at Rome was exerted in Raymond’s favour. The young Count of Toulouse himself caused his own ambassadors to promise full obedience to the See of Peter, and through them made exceedingly handsome “presents” to all who might possibly have influence with the Pope. These tactics succeeded so well that Honorius wrote favourably to Raymond, promising to send a new legate (Cardinal Romano of St. Angelo) to arrange matters; and wrote to Louis saying that the Emperor Frederic II’s proposed Crusade was so important that no other crusading indulgences could be issued for the present. The papal letter to the King went on to say that if Louis would but keep on threatening Raymond, the Count must end by giving in. The veteran Arnaut Amalric was directed to lead the local bishops in pressing Raymond VII to make no reservations in his offer of submission to the Church. The legate formally withdrew the Albigensian crusading indulgences and warranted Raymond VII as a good Catholic at a “parliament” in Paris. Louis disgustedly washed his hands of the whole matter, wrote to the Pope that he, Louis, had been played with and tricked, and that Rome might do what it liked without his help so long as his own rights as lay sovereign were not infringed. The French force which was already on foot was used to capture some of the Aquitanian castles still held for Henry III of England.
