The majority in that first meeting consisted of Mensheviks and Esers, who supported the Russian Provisional Government and the continuation of the war to the very end.
V.Volodarsky attended the congress as the representative of the Soviet government and the Central Committee of Russian Social Democratic Labour Party (Bolsheviks) (RSDLP(b)).
The former member of the Petrograd committee of RSDLP(b) Vladimir Yudovsky was elected the Chairman of Rumcherod which served as the highest authority for the Odessa Soviet Republic.
From January to March 1918 the Rumcherod militarily supported the pro-Soviet forces in the Moldavian Democratic Republic, and later opposed the troops sent into the region by Romania.
Later the Soviet republic was forced to comply with the conditions of the Treaty of Brest-Litovsk and withdraw due to the advance German-Austrian military first to Nikolayev, then to Rostov-on-Don and Yeysk.
