Until 1900, territory of this eparchy belonged to the Eastern Orthodox
Metropolitanate of Dabar and Bosnia, which in turn was under the ecclesiastical jurisdiction of the
Ecumenical Patriarchate of Constantinople. Upon the request of the
Eastern Orthodox Serbs in the region, new Eparchy of Banja Luka was created in that year, with seat in the city of Banja Luka. Bishop of Banja Luka was granted the honorary title of Metropolitan, as was the custom in
Ecumenical Patriarchate of Constantinople. After
World War I and the creation of the
Kingdom of Yugoslavia, a council of Eastern Orthodox bishops in Bosnia and Herzegovina unanimously decided to unite with other Serbian ecclesiastical provinces to form the unified
Serbian Orthodox Church, a process completed in 1920. ==List of bishops==
