The Knights Templar were financed by (St.)Bernard de Clairvaux–a Catholic. Montsegur is where the Albigensians(Cathars)made their last stand. Very tragic story. The Cathars were forced to wear yellow crosses–It was truly the first engineered genocide of a people. Several hundred years later, Hitler would require the Jews to wear yellow stars–matching the template of evil, the Cathars suffered.
He also dispatched Otto Wilhelm Rahn to the regions of Languedoc–Montsegur to be exact–to find the Holy Grail. It was believed that the Cathars possessed it. It was Esclarmonde de Foix, who legend says, became a dove, and flew east, taking the Grail with her. And legend also says that when the last Cathar died–they would return in 700 years for revenge. btw. The Cathars read the Gospel of John. St. John the first Theologian. It is also thought that they knew the secrets of the tribe of John the Baptist–
But that is another story for another day.
