All-Ukrainian Congress of Soviets

The All-Ukrainian Congress of Soviets was a political organization that played a role in the formation of Soviet Ukraine. The first All-Ukrainian Congress of Soviets convened in December 1917, under Bolshevik influence, and established a Soviet government for Ukraine. Subsequent congresses in 1918 and 1919 declared Soviet Ukraine independent and adopted its first constitution, though these actions were largely tactical responses to Ukrainian nationalism.12

Ultimately, Soviet Ukraine became part of the Union of Soviet Socialist Republics (U.S.S.R.) in 1922. While constituent republics retained a formal right to secede, their domestic affairs were limited, with significant authority vested in Communist Party organs in Moscow. The Communist Party of Ukraine was integrated into the broader Soviet Communist Party, with Moscow holding paramount power.12
