Roman Catholic Diocese of Bosnia

[3][4] The political and cultural circumstances of its foundation correspond to the time period of Croatian king Peter Krešimir IV (1058–1074).

[7][8] In the 13th and 14th centuries, the Bishops of Bosnia were mainly Dominican missionaries who were sent in to combat the spread of the Bosnian Church.

[9] At the turn of the 14th century, the Franciscans also arrived with the same purpose, at first in Usora and Soli, at the request of Stephen Dragutin of Serbia.

[10] The two orders engaged in a prolonged dispute over the control of the province, in which the Franciscans ultimately prevailed, yet the weakened diocese still succumbed to the Ottoman conquest of Bosnia in 1463.

The Diocese of Bosnia (Ðakovo) and Srijem became the present-day Archdiocese of Ðakovo-Osijek.
