The Metropolis of Kiev, Galicia and all Ruthenia was an ecclesiastical territory or archeparchy of the Ruthenian Uniate Church, a particular Eastern Catholic church. It was erected in the Polish–Lithuanian Commonwealth in 1595/96 following the Union of Brest. It was effectively disestablished by the partitions of Poland (1772–1795). Its successor — the Ukrainian Greek Catholic Church — continues to operate in the modern states of Ukraine and Poland. The first metropolitan was Michael Rohoza.
