All such hopes proved fallacious. With the development of the Albigensian troubles the attention of Innocent was directed from the Slavs. The conversions made under pressure were but temporary. The metropolitan of the province, Arringer, Archbishop of Ragusa, filled the vacant see of Bosnia with a Catharan, and, dying himself soon after, his episcopal city became a nest of heretics. The few Catholic priests scattered through the region abandoned their posts, and Catholicism grew virtually almost extinct. In 1221 it is said that in the whole of Bosnia there was not a single orthodox preacher to be heard. Equally disheartening was the course of affairs among the Bulgarians. After Calo Johannes had been crowned by a legate from Rome, his quarrels with the Latin Emperors of Constantinople led to a breach, and in the wide territories under his dominion the Cathari had full liberty of conscience.[326] At length the papal attention was again directed to this deplorable state of affairs. In 1221 Honorius III. sent his chaplain, Master Aconcio, as legate to Hungary, with orders to arouse the king and the prelates to a sense of their obligation to exterminate the heretics who were thus openly defiant. On his way the legate paused at Ragusa to superintend the election of an orthodox archbishop, after which he ordered all Dalmatia and Croatia to join in a crusade, but no one followed him, and he went alone to Bosnia, where he died the same year. Better results were promised by the ambition of Ugolin, Archbishop of Kalocsa, who desired to extend his province; he proposed to Andreas II. of Hungary that he would lead a crusade at his own cost, and king and pope promised him all the territories which he should clear of heretics, but Ugolin overrated his powers, and adopted the expedient of subsidizing with two hundred silver marks the ruler of Syrmia, Prince John, son of Margaret, widow of the Emperor Isaac Angelus. John took the money without performing his promise, though reminded of it by Honorius in 1227. Relieved from apprehension, the Bosnians deposed their Ban Stephen and replaced him with a Catharan, Ninoslav, one of the most notable personages in Bosnian history, who maintained himself from 1232 to 1250.[327]
