Krstjani

The Bosnian Church lasted in Bosnia from the thirteenth to the fifteenth century. Nominally Catholic, Bosnia saw its bishopric break with Rome in the first half of the thirteenth century, when the Hungarian-appointed bishop withdrew to Đakovo and the governor and nobles took over the choice of bishop.

Its head was a bishop called the djed, or grandfather. It kept Slavic liturgy. It was long equated with the Bogomils, a link most scholars now doubt.

Hungarian kings repeatedly launched crusades on the pretext of heresy; Pope Nicholas IV sent an Inquisition in 1291. In 1459 King Thomas turned on the church to win papal support against the Turks, and it was dismantled; the Ottomans took Bosnia in 1463.
