Along with other émigré Hungarian radicals in Soviet Russia, Pogány was set to work in the apparatus of the Communist International (Comintern), which was at the time attempting to foment general socialist revolution across Europe. The Hungarian Communists in exile were bitterly divided along factional lines. Pogány, as a member of the governing Central Committee of the Hungarian Communist Party, was closely allied to Béla Kun in the factional turmoil which ensued. The Comintern disapproved of the disorganizing impact of this intra-party war among the Hungarian Communists and ordered the feuding groups to disband in January 1922.
