Raymond Roger Trencavel

In June, Raymond of Toulouse, recognizing the potential disaster at hand, promised to act against the Cathars, and his excommunication was lifted.

The crusaders headed towards Montpellier and the lands of Raymond-Roger de Trencavel, aiming for the Cathar communities around Albi and Carcassonne.

The crusaders, led by a papal legate, Arnaud Amaury, Abbot of Cîteaux, arrived outside the town on 1 August 1209.

At the conclusion of these negotiations he was taken prisoner while still under safe conduct, and imprisoned in his own dungeon, where he died, possibly of dysentery, though there were suspicions of poisoning.

Raymond-Roger's dispossessed son, Raymond II (1204-1263), formally ceded his rights to Louis IX of France in 1247, after several failed attempts to recover his patrimony.
