The Diocese of Srijem (Latin: Dioecesis Sirmiensis) is Latin Church ecclesiastical territory or diocese of the Catholic Church in Serbia. It is a suffragan diocese in the ecclesiastical province of the Archdiocese of Đakovo-Osijek. The episcopal see of the diocese is in Sremska Mitrovica. Territory It includes Serbian part of the region of Syrmia, which is administratively divided between the Autonomous Province of Vojvodina and the City of Belgrade. The diocese includes adherents mainly from Croat and Hungarian ethnic communities. History Diocese of Syrmia was created upon the request of Ugrin Csák, Archbishop of Kalocsa in 1229. It became a suffragan bishopric of the Hungarian church administration. In 1521, after the fall of Belgrade, the region of Syrmia was overrun by Ottoman Turks. The Latin Church continued to appoint bishops for Syrmia, but they were living mainly outside their diocese. During the Austro-Turkish wars of (1683–1699) and (1716–1718), entire region of Syrmia was liberated from Turkish rule and incorporated into the Habsburg monarchy. In 1773, the Diocese of Syrmia and Diocese of Bosnia and Đakovo were joined into a single enlarged diocese that was named the Diocese of Bosnia-Đakovo and Syrmia. In 1918, the region was incorporated into newly formed Kingdom of Serbs, Croats and Slovenes, known as Yugoslavia. In 1945, region of Syrmia became part of Serbia within Yugoslavia. In 1963, name of the diocese was changed to Diocese of Đakovo or Bosnia and Srijem. After the breakup of Yugoslavia (1991–1992) there were several initiatives towards the renewal of the separate Diocese of Srijem. On 15 July 1999 the Holy See created the territory with a special authority to govern the Serbian part of the Diocese of Djakovo or Bosna and Srijem and on 1 October 1999 was established as a General Vicariate for Srijem with the residence in Petrovaradin. On 18 June 2008 the Diocese of Đakovo or Bosnia and Srijem was divided into two administrative units: the Archdiocese of Đakovo-Osijek and the Diocese of Srijem. The current bishop is Đuro Gašparović, appointed in 2008. Previously he had been the auxiliary bishop of the parent diocese.
