Symon Vasyliovych Petliura was a Ukrainian revolutionary, politician and journalist. He was the Supreme Commander of the Ukrainian People's Army (UNA) and led the Ukrainian People's Republic during the Ukrainian War of Independence, a part of the wider Russian Civil War.
Petliura was born to a family of Cossack heritage in Poltava. From an early age he embraced socialism and Ukrainian nationalism, which he advocated through his highly prolific career as a journalist. After the 1917 February Revolution overthrew the Tsarist monarchy, the Ukrainian People's Republic was proclaimed and Petliura was elected head of its military.
