→Founding and Dissolution of the UAOC
Due to the cultural differences that had developed as a result of the Polish occupation and the Union of Brest the reunion of the Orthodox Church in Ukraine with the Church of Rus' was opposed by some Ukrainian Orthodox, who began advocating the establishment of an independent Church of Ukraine. Although suppressed by the Russian Empire, following its collapse in the early 20th century supporters of an independent Ukrainian Orthodox Church held an All-Ukrainian Council (''sobor'') in Kiev that on 5 May 1920 declared the establishment of an independent Local Orthodox Church in Ukraine.
The UAOC sought for hierarchical support, but none of the hierarchs serving in Ukraine would join the Church and consequently in 1921 a group of clergy and laymen together "consecrated" Archpriest [[Vasyl Lypkivskyj]] as a bishop, enthroning him as Metropolitan of Kyiv and All Ukraine. He consequently "consecrated" other bishops for Ukraine and dioceses of the UAOC formed in Canada and the United States by Ukrainian nationalists and converts from Ukrainian Catholicism. (These eparchies later became the [[Ukrainian Orthodox Church of Canada]] and the [[
Ukrainian Orthodox Church in the United States|Ukrainian Orthodox Church of the United States]].)
The UAOC in Ukraine was dissolved following the Bolshevik occupation and annexation of eastern and central Ukraine in the 1920s. In 1924, however, the Ecumenical Patriarchate unilaterally rescinded the transfer of the Orthodox Church in what today is western Ukraine, Belarus, and Poland to the Church of Rus' and established it as the independent [[Church of Poland]]. Although operating on the territory of interwar Poland and officially called the Polish Orthodox Church, this new Local Orthodox Church's flock was primarily Ukrainian and Belorussian in composition.
