Excerpts from Books and Wikipedia
"Raymond VII agreed to the deal, which was signed in Paris in 1229. The Treaty of Paris brought Toulouse more firmly under the control of the French throne, but it also brought peace to the young count’s battered domains. As further proof of his willingness to exterminate heresy, Raymond played host to a church council that met in Toulouse late in 1229. The council affirmed the establishment of the new University of Toulouse and laid out exactly how the extermination should proceed. . . . This method of searching out heretics by appointed committee diffused the hunt out among both priests and laypeople: both were now authorized to inquire into the orthodoxy of their neighbors. Young Raymond had brought an end to the Albigensian Crusade; but in doing so, he had allowed the Council of Toulouse to establish the Inquisition." [Bauer: Renaissance, p. 260]
