Гонорий III
In 1221, Pope Honorius III demanded that the "heretics" (Bogomils) be exterminated in Bosnia. His chaplain Aconcio was unable to gain any followers in Ragusa, and died while in Bosnia. Ugrin Csák, the Archbishop of Kalocsa, proposed to Andrew II of Hungary that he would lead the Bosnian Crusade, and the king and pope promised him all lands that he would clear of heretics. Ugrin overrated himself, and instead gave 200 silver marks to John Angelos, the ruler of Syrmia, to perform the task. John took the money but never acted against the Bogomils, despite being reminded of his obligation by Pope Honorius III in 1227.
