The Metropolis of Kiev is a metropolis of the Eastern Orthodox Church that was transferred to the Patriarchate of Moscow in 1685. From 988 AD until 1596 AD, the mother church of the Metropolis of Kiev, Galicia and all Rus' had been the Ecumenical Patriarchate of Constantinople. The Moscow Patriarchate was a Caesaropapist entity that was under the control of the Russian state. While nominally ruled by a metropolitan bishop, since its inception, the secular authorities of the Tsardom of Russia altered the territorial remit of the Kyiv metropolis, stripped it of its suffragan sees and transformed the office from an ecclesiastical province to an archbishopric to an honorific or empty title.
Following the Russian Revolution, it became an exarchate of the Russian Orthodox Church (ROC). Following the collapse of the Soviet Union, it was transformed into the Ukrainian Orthodox Church of the Moscow Patriarchate (UOC-MP) with a degree of independence in the territory of the modern state of Ukraine. The primate of the UOC-MP — Onufriy — is styled the "Metropolitan of Kyiv and All Ukraine". It is a matter of debate as to whether the UOC-MP has full ecclesial independence (autocephaly) or merely enjoys extended autonomy while ultimate control continues to reside in Moscow.
