The Diocese of Mostar-Duvno is part of the ecclesiastical province of Vrhbosna and thus is a suffragan of that archdiocese.
[3] With the Austro-Hungarian occupation of Bosnia and Herzegovina in 1878, Pope Leo XIII restored the regular church hierarchy there with the papal bull Ex hac augusta on 5 July 1881, thus establishing the Diocese of Mostar-Duvno.
[7] The first secular priest appointed bishop was Petar Čule who had the longest tenure of 38 years, serving from 1942 to 1980.
[8] His successor Pavao Žanić reigned for 13 years, from 1980 to 1993,[9] marking the shortest episcopacy.
His successor Ratko Perić held the episcopal office for 27 years, from 1993 to 2020, when he was succeeded by the incumbent bishop Petar Palić.
