Bulgarian Exarchate
The Bulgarian Exarchate (Bulgarian: Българска екзархия Bǎlgarska ekzarhija) was the official name of the Bulgarian Orthodox Church before its autocephaly was recognized by the Ecumenical See in 1945 and the Bulgarian Patriarchate was restored in 1953.
The Exarchate (a de facto autocephaly) was unilaterally (without the blessing of the Ecumenical Patriarch) promulgated on May 23 [O.S. May 11] 1872, in the Bulgarian church in Constantinople in pursuance of the March 12 [O.S. February 28] 1870 firman of Sultan Abdülaziz of the Ottoman Empire.
The foundation of the Exarchate was the direct result of the struggle of the Bulgarian Orthodox against the domination of the Greek Patriarchate of Constantinople in the 1850s and 1860s. In 1872, the Patriarchate accused the Exarchate that it introduced ethno-national characteristics in the religious organization of the Orthodox Church, and the secession from the Patriarchate was officially condemned by the Council in Constantinople in September 1872 as schismatic. Nevertheless, Bulgarian religious leaders continued to extend the borders of the Exarchate in the Ottoman Empire by conducting plebiscites in areas contested by both Churches.
