The article examines the relationship between the Ukrainian Communist Party (UCP) and the Comintern, and attempts to assess the possibility of Ukapists joining the Comintern or uniting with the Communist Party (Bolsheviks) of Ukraine. The controversy within the party between the so-called “left faction” that arose after the split in 1923 and the main composition of the party is touched upon. Based on the analysis of verbatim protocols and materials for the meeting of the Ukrainian Commission of the Comintern, it is concluded that the leaders of the Ukrainian Communist Party, until the adoption of the resolution of the Comintern Commission on their issue, maintained their opposition position, while understanding that maintaining an opposition party in the USSR was impossible. The Comintern and the CP(b)U ignored most of the statements of the Ukapists, acting in the spirit of a political monopoly. On December 24, 1924, the Comintern adopted a resolution dissolving the Ukrainian Communist Party.
