The Eparchy of Marča () was an Eastern Christian ecclesiastical entity taking two forms in the 17th century: an Eastern Orthodox eparchy and an Eastern Catholic vicariate. The term was derived from the name of the monastery at Marča (today Stara Marča) near Ivanić-Grad, Habsburg monarchy (present-day Zagreb County, Republic of Croatia).
Although Serbian Orthodox bishop Simeon Vratanja traveled to Rome in 1611 and formally accepted jurisdiction of the Pope over this bishopric, until 1670 Serb bishops continued to recognize the jurisdiction of the Serbian Patriarchate of Peć and struggled against conversion attempts by Roman Catholic bishops from Zagreb. This semi-union existed until the 1670 appointment of Pavle Zorčić as bishop. All Serb Orthodox clergy who objected to the union were arrested and sentenced to life in prison in Malta, where they died. The bishopric eventually became the Eastern Catholic Eparchy of Križevci.
Name
The name Marča was derived from the name of the nearby hill, Marča. Other names used for this bishopric include Svidnik (Svidnička eparhija), Vretanija (Vretanijska eparhija), and the "Uskok" bishopric.
History
Background
After the Ottoman capture of Smederevo fortress in 1459 and fall of Bosnia 1463 different populations of Orthodox Christians moved into Syrmia and by 1483 perhaps 200,000 Orthodox Christians moved into central Slavonia and Syrmia At the beginning of the 16th century settlements of Orthodox Christians were also established in western Croatia. In the first half of the 16th century Serbs settled Ottoman part of Slavonia while in the second part of the 16th century they moved to Austrian part of Slavonia. In 1550 they established the Lepavina Monastery. Orthodox Christians which settled Military Frontier from area of the Ottoman Empire were most often called Vlachs, while most documents state that the Vlachs coming "from Bosnia" or "from Turkey" ie from the Bosnian pashaluk, also they were of different ethnic origin and from 1611 under the Greek Catholic bishops of Marča. At the end of the 16th century a group of Serb Orthodox priests built a monastery dedicated to Saint Archangel Gabriel () on the foundations (or near them) of the deserted and destroyed Catholic Monastery of All Saints.
Eparchy of Vretanija
Some scholars promoted the view that Marča, as a diocese of the Serbian Patriarchate of Peć, was established in the late 16th century (1578 or 1597). This theory was used as evidence of the long-time presence of the Serb population on the northern bank of river Sava.
In 1609 Serb Orthodox priests established Marča Monastery in Marča near Ivanić-Grad. In the same year the Marča Monastery became a seat of the Eparchy of Vretanija. This bishopric was the westernmost eparchy of the Serbian Patriarchate of Peć. Its name was derived from Vretanija () which was a part of the title of the Serbian Patriarch. Its first bishop was Simeon Vratanja, appointed in 1609 by the Serbian Orthodox patriarch Jovan to the position of bishop of all Orthodox Serbs who settled to Croatia. This appointment marked establishment of the Eparchy of Vretanja in 1609 according to historian Aleksa Ivić.
Establishment as Eastern Catholic church
Being under strong pressure from Croatian clergy and state officials to recognize the jurisdiction of the Pope, and to convert the population of his bishopric to Eastern Catholicism, Simeon Vratanja visited Pope Paul V in 1611 and recognized his jurisdiction and maybe the Union of Florence as well. The strongest influence to his decision had Martin Dobrović, who convinced Simeon to recognize papal jurisdiction and to accept the Eastern Catholicism.
In November 1611, the Pope appointed Simeon as bishop of Serbs of Slavonia, Croatia and Hungary. He also granted all estates that once belonged to the Catholic Monastery of All Saints to the Marča Monastery. Pope Paul V granted to Bishop Simeon, Greek Catholic episcopal authority in Croatia, Hungary, Slavonia and Žumberak, which was also confirmed by Archduke Ferdinand and Bishop of Zagreb Petar Petretić. From "Vlach" Bishop Simeon as he was called by authorities from Vienna it was expected to implement unification of Orthodox Vlachs with the Catholic Church in area of Croatian Military Frontier and Slavonian Military Frontier. On 21 November 1611 Marča was established as an eparchy (bishopric) of the Eastern Catholic Church, having around 60,000 believers.
Period of semi-union (1611–1670) Simeon continued to use Slavic language, Julian calendar and maintained connection with Serbian Patriarchate of Peć.
