In 1448, the Council of Moscow's Bishops, without the consent of the Ecumenical Patriarch, appointed Jonah, Bishop of Riazan, Metropolitan of Kyiv. This event is considered the beginning of the separation of the Church of Moscovy. After the Union of Florence, before the fall of Constantinople in 1453, the Church of Moscovy, which was under the jurisdiction of the Ecumenical Patriarchate as part of the Metropolitanate of Kyiv, seceded. Metropolitan Jonah, who died in 1461, was the last metropolitan in Moscow to hold the title of ""Kyiv and All Rus"." His successor at the department is already called "Moscow and all of Rus." The Moscow metropolitanate was in a state of unrecognized state – until its transformation into the Moscow patriarchate in 1589, ie 141 years.
