Department of Soviet Propaganda at the Executive Committee of the Soviet of Workers' Deputies of Odessa
From May 1917 onward, the sphere of political influence in Odessa was in the hands of the Soviet of Workers' Deputies that was being supported by Rumcherod -- the Central Executive Committee of Soviets of the Romanian Front, Black Sea Fleet and Odessa region. Soviet influence in Odessa increased following the 1917 October Revolution in Petrograd (St. Petersburg). In January 1918, a Soviet coup took hold in Odessa and it culminated in the short-lived Odessa Soviet Republic. The Republic toppled in March after Odessa was taken by German and Austrian troops. In turn, White Russian (anti-Bolshevik) forces took control of Odessa until February 1920, when it was retaken by the Soviets.
