History.
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 of this 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. 
In 1918, all Orthodox bishops in Bosnia and Herzegovina reached a unanimous decision to join with other Serbian ecclesiastical provinces into united Serbian Orthodox Church. Arrangements with the Ecumenical Patriarchate were made, and the canonical process of unification was completed in 1920. Since then, Eparchy of Banja Luka has been part of the Serbian Orthodox Church.
