Providing refuge to those labeled heretics, including Bogomils, was a recurrent pretext for Hungarian rulers to declare crusades against Bosnia and extend their influence in the region. A first Hungarian complaint to the Pope was averted by the public abjuration of the Bosnian ruler Ban Kulin, close relative of Stefan Nemanja, in 1203. A second Hungarian crusade against Bosnia on Bogomil heresy pretext was launched in 1225, but failed. In 1254, rebelling against the Papal order to accept a Hungarian bishop, the Bosnian Church chose the schism. In the following centuries, the Bosnian Church and the heretic sect of the Bogomils came to be identified with each other, due to the scarcity of documents after the Ottoman conquest.
