The case of the Seigneurs de Niort, powerful nobles of Fenouillèdes, who had taken part in Trencavel’s insurrection, is interesting from the light which it throws upon the connection between the religion and the politics of the time, the difficulties which the Inquisition experienced in dealing with stubborn heresy and patriotism, and the damage inflicted on the heretic cause by the abortive revolt. The three brothers--Guillem Guiraud, Bernard Otho, and Guiraud Bernard--with their mother, Esclarmonde, had long been a quarry which both the inquisitors and the royal seneschal of Carcassonne had been eager to capture. Guillem had earned the reputation of a valiant knight in the wars of the crusades, and the brothers had managed to hold their castles and their power through all the vicissitudes of the time. In the general inquisition made by Cardinal Romano in 1229 they were described as among the chief leaders of the heretics, and the Council of Toulouse, at the same time, denounced two of them as enemies of the faith, and declared them excommunicate if they did not submit within fifteen days. In 1233 we hear of their having, not long before, laid waste with fire and sword the territories of Pierre Amiel, Archbishop of Narbonne, and they had assailed and wounded him while on his way to the Holy See, an exploit which led Gregory IX. to order the archbishop, in conjunction with the Bishop of Toulouse, to proceed against them energetically, while at the same time he invoked the secular arm by a pressing command to Count Raymond. It was probably under this authority that Bishop Raymond du Fauga and the Provost of Toulouse held an inquest on them, in which was taken the testimony of Pierre Amiel and of one hundred and seven other witnesses. The evidence was conflicting. The archbishop swore at great length as to the misdeeds of his enemies. They were all heretics. At one time they kept in their Castle of Dourne no less than thirty perfected heretics, and they had procured the assassination of André Chaulet, Seneschal of Carcassonne, because he had endeavored to obtain evidence against them. Other witnesses were equally emphatic. Bernard Otho on one occasion had silenced a priest in his own church, and had replaced him in the pulpit with a heretic, who had preached to the congregation. On the other hand, there were not wanting witnesses who boldly defended them. The preceptor of the Hospital at Puységur swore to the orthodoxy of Bernard Otho, and declared that what he had done for the faith and for peace had caused the death of a thousand heretics. A priest swore to having seen him assist in capturing heretics, and an archdeacon declared that he would not have remained in the land but for the army which Bernard raised after the death of the late king, adding that he believed the prosecution arose rather from hate than from charity. Nothing came of this attempt, and in 1234 we meet with Bernard Otho as a witness to a
