Ukrainian Supreme Liberation Council (Українська головна визвольна рада, or УГВР; Ukrainska holovna vyzvolna rada, or UHVR) was a body formed toward the end of the Second World War by members of the Ukrainian Insurgent Army (UPA) and the Organization of Ukrainian Nationalists (OUN) to provide political leadership for Ukrainian independentist forces. It proclaimed itself the ‘supreme organ of the Ukrainian people in its war of revolutionary liberation.’ The founding meetings of the UHVR were held on 11–15 July 1944. By the 1950s, the UHVR ceased to exist within Ukraine. Some of its members left the country and established at the end of 1944 its External Representation (Zakordonne predstavnytstvo, or ZP UHVR), which was headed by Ivan Hrynokh. The general secretary was Mykola Lebed, who served as the UHVR's external liaison officer and director of its information bureau. Until 1948, the Foreign Sections of the OUN (ZCh OUN), led by Stepan Bandera, supported the ZP UHVR. However, ideological, tactical, and personal disagreements soon arose. Only the new faction that split from Bandera in 1954, the OUN Abroad (OUNz), continued to cooperate with the ZP UHVR. In 1952, the ZP UHVR established the research and publishing institution Prolog Research Corporation, and in 1961 it launched the journal Suchasnist'.
