Canon law of the Eastern Orthodox Church in the context of "Dogma"

Eastern Orthodoxy, otherwise known as Eastern Orthodox Christianity or Byzantine Christianity, is one of the three main branches of Chalcedonian Christianity, alongside Catholicism and Protestantism. Like the Pentarchy of the first millennium, the mainstream (or "canonical") Eastern Orthodox Church is organised into autocephalous churches independent from each other. In the 21st century, the number of mainstream autocephalous churches is seventeen; there also exist autocephalous churches unrecognized by those mainstream ones. Autocephalous churches choose their own primate. Autocephalous churches can have jurisdiction (authority) over other churches, some of which have the status of "autonomous" which means they have more autonomy than simple eparchies.

Many of these jurisdictions correspond to the territories of one or more modern states; the Patriarchate of Moscow, for example, corresponds to Russia and some of the other post-Soviet states. They can also include metropolises, bishoprics, parishes, monasteries, or outlying metochia corresponding to diasporas that can also be located outside the country where the primate resides (e.g., the case of the Ecumenical Patriarchate of Constantinople whose canonical territory is located partly in northern Greece and the east); sometimes they overlap (the case of Moldova where the jurisdictions of the patriarchs of Bucharest and of Moscow overlap).

The Eastern Orthodox Church, officially the Orthodox Catholic Church and commonly known simply as the Orthodox Church, is a communion composed of up to seventeen separate autocephalous (self-governing) hierarchical churches that profess Eastern Orthodoxy and recognise each other as canonical (regular) Eastern Orthodox Christian churches.

Each constituent church is self-governing; its highest-ranking bishop called the primate (a patriarch, a metropolitan or an archbishop) reports to no higher authority. Each regional church is composed of constituent eparchies (or dioceses) ruled by bishops. Some autocephalous churches have given an eparchy or group of eparchies with varying degrees of autonomy (meaning they have limited self-government). Such autonomous churches maintain varying levels of dependence on their mother church, usually defined in a tomos or another document of autonomy. In many cases, autonomous churches are almost completely self-governing, with the mother church retaining only the right to appoint the highest-ranking bishop (often an archbishop or metropolitan) of the autonomous church.

Metropolitan of Kyiv is an episcopal title that has been created with varying suffixes at multiple times in different Christian churches, though always maintaining the name of the metropolitan city — Kiev (Kyiv) — which today is located in the modern state of Ukraine. The church was canonically established and governed by the Ecumenical Patriarch of Constantinople in Kievan Rus'. Following the Council of Florence and the Union of Brest, there are now parallel apostolic successions: in the Russian Orthodox Church, the Orthodox Church of Ukraine, the Ruthenian Uniate Church and its successors. This list contains the names of all the metropolitan bishops (hierarchs) who have claimed the title. It is arranged chronologically and grouped per the claimed jurisdiction.

The Metropolis of Kiev, Galicia and all Rus' was a metropolis of the Ecumenical Patriarchate of Constantinople in the Eastern Orthodox Church that was erected in 1620. The dioceses (eparchies) included the Eparchy of Kiev itself, along with the eparchies of Lutsk, Lviv, Mahilioŭ, Przemyśl, Polatsk, and Chernihiv. The dioceses lay in the territory of the Polish–Lithuanian Commonwealth, which was at war with the Tsardom of Moscow for much of the 17th century. Around 1686, the Kiev and Chernihiv dioceses became Moscow-controlled territory. At the same time, the metropolis transferred from the ecclesiastical jurisdiction of the Ecumenical Patriarchate of Constantinople to the Patriarchate of Moscow in 1686. It is a matter of dispute as to whether this de facto transfer was also de jure or canonical.

The Metropolis of Kiev and all Rus' (Ukrainian: Митрополит Київський та всієї Русі, romanized: Mytropolyt Kyivskyi ta vsiiei Rusi) was a metropolis of the Eastern Orthodox Church that was erected on the territory of Kievan Rus'. It existed between 988 AD and 1590s AD. The long lasting "tug of war" between bishops from the Grand Duchy of Lithuania and bishops of the Principality of Moscow resulted in reorganization of the metropolis as the bishops from Moscow refused to recognize decisions of the Ecumenical Patriarch of Constantinople. Canonically, it was under the jurisdiction of the Ecumenical Patriarchate of Constantinople. The metropolitan seat (cathedra) was located in the city of Kiev until it was moved to Vladimir-na-Klyazme in 1299 and then Moscow in 1325.

The metropolis was later revived in the territory of the Polish–Lithuanian Commonwealth from 1620 AD to 1686 AD as an exarchate of the Ecumenical Patriarchate. Again, to reflect its exclusion from the Tsardom of Russia, this episcopal title was renamed the "Metropolis of Kiev, Galicia and all Rus'". The fate of the metropolis after that date is a matter of dispute: according to the Orthodox Church of Ukraine, the metropolis was uncanonically annexed or was in abeyance until it received the tomos of autocephaly from the Ecumenical Patriarch; on the other hand, the Russian Orthodox Church (ROC) maintains that it was absorbed by the Patriarchate of Moscow and all Rus' and is currently an exarchate of the ROC that styles itself on the Ukrainian Orthodox Church (Moscow Patriarchate) (UOC-MP).
