Diocese of Duvno
The Diocese of Duvno (Latin: "Dioecesis Dumnensis" or "Dioecesis Dalminiensis") was a Latin rite diocese of the Catholic Church that was established in the 14th century with a seat in present-day Tomislavgrad in Bosnia and Herzegovina. From the late 17th century onwards, it was administered by the bishops of Makarska, though by the 19th century it was only a titular see. On 5 July 1881 Pope Leo XIII incorporated it into the newly established Diocese of Mostar-Duvno. Its last titular bishop was Cyryl Lubowidzki, who held the title until 1897, when it was formally suppressed . History. Christianisation of the area around ancient Delminium intensified during the Late Antique period, especially in the area of Buško Blato, connecting major cities in the region including Salona, Argentarium, and Sirmium. There were four basilicas in the area of Buško Blato; these were located in present-day Prisoje, Bukova Gora, Podgradina, and Vinica. Closer to present-day Tomislavgrad were four antique churches in Crvenice, Borčani, and Karaula in Tomislavgrad. There was also one ancient church in Šuica. Delminium was unable to recover after the Barbarian Invasion and is not mentioned in the early Medieval sources. Contrary to a number  of historians' previously-held belief that there was an ancient diocese with a seat in Delminium, Ante Škegro argues that there was no such diocese. The confusion came with a misinterpretation of a document from the Second Council of Salona of 533. The document supposedly referred to a bishop in the area of "delmensis", which was identified with Delminium, but it actually made reference to the Dalmatian Hinterland. Pope Clement V established the diocese in the 14th century and regularly appointed bishops until 1663 when its territory merged into the Diocese of Makarska. The last bishop, Mihalj Jahnn, the Czech  Franciscan, found a land and Christian population which had been devastated. On 24 March 1846, the Apostolic Vicariate of Herzegovina was founded when it separated from the Apostolic Vicariate of Bosnia and from the Diocese of Dubrovnik. The vicariate encompassed the area of the former Diocese of Duvno. Regular ecclesiastical hierarchy was restored in Bosnia and Herzegovina in 1881. Duvno was located within the boundaries of the Mostar diocese, so the bishop of Mostar adopted the titles "Bishop of Duvno" and "Bishop of Mostar-Duvno" in order to maintain the memory of the Duvno Diocese.
