''For a list of metropolitans before the seat of the
Metropolis of Kiev and all Rus' was moved to Moscow, see
List of metropolitans and patriarchs of Kyiv.'' Isidore of Kiev, who was of Greek origin, submitted to the articles of the
Bull of Union with the Greeks which united the Orthodox Church in Russia with the
Latin Church. Following his acceptance of the
Council of Florence, Isidore returned to Moscow in 1441 as a
Ruthenian
cardinal. He was arrested by the
Grand Prince of Moscow —
Vasily II, and accused of
apostasy. The Grand Duke deposed Isidore and in 1448 installed his own candidate as Metropolitan of Kiev —
Jonah. This was carried out without the approval of Patriarch
Gregory III of Constantinople. When Isidore died in 1458, the Orthodox
dioceses within the territory of the
Grand Duchy of Lithuania, including Kiev, were reorganized. The metropolitan see was moved to
Vilnius, the capital of the Grand Duchy of Lithuania. A
parallel succession to the title ensued between Moscow and Vilnius. == Metropolitans of Moscow and all Rus' (1448–1589) ==
