The earliest interference with heresy occurs at the end of the twelfth century, when the Archbishop of Spalatro, doubtless under impulsion from Innocent, drove out a number of Cathari from Trieste and Spalatro. They found ready refuge in Bosnia, where Culin welcomed them. Vulcan, King of Dalmatia, who had designs upon Bosnia, in 1199 represented to Innocent the deplorable prevalence of heresy there, and suggested that Emeric, King of Hungary, should be urged to expel the heretics. Innocent thereupon wrote to Emeric, sending him the severe papal decretal against the Patarins of Viterbo as a guide for his action, and ordering him to cleanse his territories of heresy and to confiscate all heretical property. Culin seems to have taken the initiative by attacking Hungary, but at the same time he tried to make his peace with Rome by asserting that the alleged heretics were good Catholics. He sent some of them, with two of his prelates, to Innocent for examination, and asked for legates to investigate the matter on the spot. In 1202 the pope accordingly ordered his chaplain, Giovanni da Casemario, and the Archbishop of Spalatro, to proceed to Bosnia, where, if they found any heretics, including the Ban himself, they were to be prosecuted according to the rigor of the canons. Giovanni successfully accomplished this mission in 1203. He reported to Innocent a pledge given by the Cathari to adopt the Latin faith, while, to insure the maintenance of religion, he recommended the erection of three or four additional bishoprics in the territory of the Ban, which were ten days’ journey in extent and which yet had but one see, of which the incumbent was dead. At the same time King Emeric wrote that Giovanni had brought to him the leaders of the heretics, and he had found them converted to orthodoxy. Culin’s son had likewise presented himself, and had entered into bonds of one thousand marks, to be forfeited in case he should hereafter protect heretics within his dominions. The triumph of the Church seemed assured, especially when, in the same year, Calo Johannes, the Emperor of the Bulgarians, applied to Innocent to have cardinals sent to crown him, and professed himself in all things obedient to the Holy See.[325]
