History.
Roman Catholic Diocese of Syrmia was created sometime after the final Hungarian conquest of the region of Syrmia at the end of 12th and the beginning of 13th century. In 1521, after the fall of Belgrade, the region of Syrmia was overrun by Ottoman Turks. Roman Catholic 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.
