Pope Innocent—is there not bitter satire in the name—in 1203 sent a legate into the southern provinces, Peter of Castelnau by name. This man visited Toulouse, but his efforts there to confute the heresy failed completely. Hopeless of success and mortified in his vanity Peter appealed to Pope Innocent to adopt drastic measures, and Innocent bade him require Raymond, Count of Toulouse, to suppress Albigensianism throughout his dominions by fire and sword. He was ordered, on pain of excommunication, to become the inquisitor and executioner of his subjects. At the same time he deposed Raymond, Bishop of Toulouse, an amiable, liberal-minded man, and put in his place the firebrand Foulques, who had been a troubadour, and notorious for his licentious verses.

Raymond VI of Toulouse promptly refused to do what was required of him, whereupon Innocent, in 1207, pronounced his excommunication.

Possibly the Count may have let slip some expression of disgust at the conduct of the papal legate, and a wish to be well rid of him, as did Henry II with reference to Becket. The result was the same; a knight killed Peter of Castelnau in 1208 as he was crossing the Rhone. This filled up the measure of Innocent’s wrath. He hurled the most dreadful imprecations against the Count, and loudly summoned all Christendom to a war of extermination against the Albigenses. “Anathema to the Count of Toulouse! Remission of all sins to such as arm against these pestilential Provincials. Go forward, soldiers of Christ! May the heretics perish out of the land, and let colonies of Christians be established in their room!”

Dukes and bishops, counts and viscounts, flew to the standard of the Cross, eager to glut themselves on the spoil of the South, so rich with merchandise, and at the same time to gain eternal salvation by violation and murder. Three armies invaded the South under the supreme command of a needy northern knight, Simon de Montfort.

The Pope was as subtle as he was remorseless. In order to weaken the opposition in the South he had entered into negociation with Raymond of Toulouse, and had deluded him into expectations of pardon, till the Crusaders were on him. They began with Béziers, although the viscount was known to be a Catholic. The city was taken and the inhabitants massacred. The Abbot of Citeaux, the legate, wrote regretfully to Innocent that he could only answer for having cut the throats of twenty thousand.

Then the papal host marched to Cascassonne, where they hung fifty prisoners, and burned four hundred Albigenses alive.

Raymond was now offered pardon if he would dismiss his soldiers, level his castles and the walls of his towns, give the Inquisition a free hand in his domains, and make every householder pay a tax of four deniers to the papal treasury. The Count indignantly refused, and the legate again sounded the attack. Raymond was defeated at Castelnaudary, and compelled to fly to Aragon. The conquerors seized on his territory, which the needy knights of the north parcelled out among themselves; and they diverted themselves in hunting out the heretics and burning them.

Urged on by his kinsman, the Count of Toulouse, Peter II, King of Aragon, passed the Pyrenees with an army, and was at once joined by the Count of Foix and many other nobles. A battle was fought at Muret in 1213, in which the King was killed, the army routed, and the nobles of Languedoc dispersed. This sealed the fate of the country. The Council of the Lateran, held two years later, ratified the deposition of Raymond, who, along with the counts of Foix and Cominges, had appeared before the Council, with bitter complaints in their mouths of the way in which their subjects had been slaughtered wholesale and the country laid waste. At once up sprang Foulques, Bishop of Toulouse. “Foix,” said he, “swarms with heretics. The sister of the Count intercepted and cut to pieces six thousand Germans, Crusaders, on their way to join the legate.”

“Soldiers of the Cross!” retorted the Count of Foix fearlessly. “They were mere robbers, committing every possible outrage in the country.”

Then the Baron de Vilamour rose, and in a cold voice gave a detailed account of the horrors, the rapes, the murders, the ravages committed by the Soldiers of the Cross, those sent forth by the Holy See with assurance of gaining Heaven thereby. As he spoke Innocent’s head sank on his breast, and he heaved a sigh; some sense of shame stole into his heart. He went to meet his account in 1216, and was succeeded by Honorius III.
