Ukrainian People's Republic

The Ukrainian People's Republic or Ukrainian National Republic (; abbreviated УНР, UNR), a predecessor of modern Ukraine, was declared (on 10 June 1917) - at first as a part of the Russian Republic after the Russian Revolution - but proclaimed its independence on 25 January 1918. During its short existence the republic went through several political transformations from the socialist-leaning republic headed by the Central council with its General secretariat to the national republic, led by the Directorate and by Symon Petlyura. Between April and December 1918 the Ukrainian People's Republic did not function, having been overthrown by the Ukrainian State of Pavlo Skoropadsky. From autumn 1919 the UNR operated as an ally of the Second Polish Republic. But by then the state de facto no longer non-existed. The 18 March 1921 Treaty of Riga between the Second Polish Republic, Soviet Russia (acting also on behalf of Soviet Belarus) and Soviet Ukraine sealed the fate of the Ukrainian People's Republic.
