Greek Catholic Eparchy of Križevci

The Ottoman wars in Europe caused a number of Christian refugees, Orthodox Serbs, to migrate to the Military Frontier of the Habsburg monarchy (in south-central Croatia and in most of Slavonia) during the 16th and 17th centuries.

In particular after the Ottoman defeat in Battle of Sisak of 1593, the Habsburg tried to established an ecclesiastical jurisdiction in full communion with Rome and separated from the Serbian Orthodox Church.

After negotiations, it was decided to establish a particular Byzantine Rite jurisdiction in the form of an apostolic vicariate based in the monastery of Marča (located near Ivanić Grad).

The basis for the creation of Apostolic Vicariate of Marča was formally enabled by Pope Paul V on 21 November 1611 with the decree Divinae Majestatis arbitrio, and the administration of the Vicariate was given to eparchs (bishops) who bore the title Episcopus Platæensis (from Plataea, the titular see they were assigned to[2]), while the Habsburg government called this see Episcopatus Svidnicensis or Episcopatus Maciensum (Eparchy of Marča).

[3] On 17 November 1735, the supporters of the Serbian Orthodox Church occupied by force of arms the monastery of Marča and two years later, on 17 June 1737, set fire to it.

[11] In comparison, the most recently published census results for the Republic of Croatia, those of 2001, report only 6,219 Croatians defining themselves specifically as Greek Catholics.

The first Greek Catholic priest from Croatia came to the United States of America in 1902, whose work among Byzantine-Rite Croatians in Cleveland was encouraged by the bishop of Križevci.
