paragraph_text: The Bosnian Crusade was fought against unspecified heretics from 1235 until 1241. It was, essentially, a Hungarian war of conquest against the Banate of Bosnia sanctioned as a crusade. Led by the Hungarian prince Coloman, the crusaders only succeeded in conquering peripheral parts of the country. They were followed by Dominicans, who erected a cathedral and put heretics to death by burning. The crusade came to an abrupt end when Hungary itself was invaded by Tatars. The crusaders were forced to withdraw and engage their own invaders, most of them perishing, including Coloman. Later popes called for more crusades against Bosnia, but none ever took place. The failed crusade led to mistrust and hatred for Hungarians among the Bosnian population that lasted for centuries.
