It was in vain that on Culin’s death the King of Hungary appointed a Catholic Ban Zibisclave. It was in vain that in 1216 the Pope sent the sub-deacon Aconcius to labour at the conversion of the heretics. The Bogomiles only gained strength, and their faith struck firmer roots in the neighbouring countries of Croatia, Dalmatia, Istria, Carniola, and Slavonia. But Rome, in the Albigensian crusades, had already tasted Christian blood, and resolved to have recourse to the same weapons in Bosnia which she had employed so efficaciously in Provence. An Archbishop of Colocz was at hand to play the part of the Abbot of Citeaux. In 1222 he entered Bosnia at the head of an Hungarian host, and used the sword with such good effect that he had shortly possessed himself of the provinces of ‘Bosna, Ussora, and Soy.’ Zibisclav, who had defected from the true faith, saw himself reduced to abjure his errors and to fling himself at the toes of St. Peter, and the Pope was graciously pleased ‘to embrace sincerely in the arms of his charity both his person and his lands, and all the goods that he at the present possessed.’[57] But Zibisclav’s subjects were not inclined to follow the example of their Ban. On the contrary, they hardened their hearts, and in the very year, 1233, in which this fond embrace took place, a Bogomilian ‘pope’ or bishop continued to flourish and exercise a powerful authority in Bosnia. A new crusade was necessary. Coloman, the brother of the King of Hungary,[58] was the De Montfort of the occasion, and in 1238 entered Bosnia with a large army to exterminate the heretics. He extended his havoc through the whole country, and even ‘purged,’ we are told, the principality of Chelm, which answers to the south-western part of the Herzegovina. From this period onwards the history of Bosnia for centuries consists of little more than a series of such bloody inroads; but there are here none of those details which secure for the heretics of Alby the commiseration of mankind. Cities are sacked, but there is not here a Beziers or Carcassonne; the first germs of a civilization are trodden under foot, but these are not the full-blown roses of Provence; troubadours of a kind there doubtless were here, too, but it was in barbarous Sclavonic tongue, and not in the polished _Langue d’Oc_ that they poured forth ‘their unpremeditated lay,’ and the sound of their lyre died away among the mountains that gave them birth.[59]
