Byzantine Church of Croatia, Serbia and Montenegro

The Greek Catholic Church of Croatia, Slovenia, Bosnia-Herzegovina and Serbia is an Eastern Catholic Church sui iuris of the Byzantine Rite which is in full union with the Roman Catholic Church. It consists of the Eparchy of Križevci and the Apostolic Exarchate of Serbia. The Eparchy of Križevci has been headed by Bishop Nikola Kekić since his appointment in 2009 and the Apostolic Exarchate of Serbia has been headed by Bishop Đura Džudžar since his appointment in 2003.

Until 2001, the Greek Catholic Eparchy of Križevci had full jurisdiction over all Eastern Catholics of the Byzantine Rite throughout the entire territory of former Yugoslavia, including all of its successor states: Croatia, Slovenia, Bosnia-Herzegovina, Serbia, Montenegro and Macedonia. During that time, it mostly gathered its faithful among the Croats in central and eastern Croatia, among the Rusyns or Ukrainians in eastern Croatia, northern Bosnia and northern Serbia and among Macedonians in Macedonia.
