Autocephaly

There developed the pentarchy, i.e., a model of ecclesiastical organization where the universal Church was governed by the primates (patriarchs) of the five major episcopal sees of the Roman Empire: Rome, Constantinople, Alexandria, Antioch, and Jerusalem.

When the Patriarch of Antioch claimed the Church of Cyprus was under its jurisdiction, the Cypriot clergy denounced this before the Council of Ephesus.

In Eastern Orthodoxy, the right to grant autocephaly is nowadays a contested issue, the main opponents in the dispute being the Ecumenical Patriarchate, which claims this right as its prerogative,[6][7] and the Russian Orthodox Church (the Moscow Patriarchate), which insists that one autocephalous jurisdiction has the right to grant independence to one of its components.

[11] In May 1872, the Bulgarian Exarchate, set up by the Ottoman government two years prior, broke away from the Ecumenical Patriarchate, following the start of the people's struggle for national self-determination.

The Bulgarian Church was recognized in 1945 as an autocephalous patriarchate, following the end of World War II and after decades of schism.

The autocephalous status of the Romanian Church, legally mandated by the local authorities in 1865, was recognized by the Ecumenical Patriarchate in 1885, following the international recognition of the independence of the United Principalities of Moldavia and Wallachia (later Kingdom of Romania) in 1878.

[13][14][15] In September 1922, Albanian Orthodox clergy and laymen proclaimed autocephaly of the Church of Albania at the Great Congress in Berat.

[19] Such honorary uses of the adjective autocephalous were recorded in various Notitiae Episcopatuum and other sources, mainly from the early medieval period.
