According to the sources and the works published by the Institute for Party History of the Central Committee of the Hungarian Communist party (HCP), there is no precise information concerning the number of its followers in 1919. According to other works, other leaders were Ferenc Munnich, Frigyes Karikas, Matyas Rakosi, Sandor Kellner, and Gyula Alpari—all of whom, however, were not among the original "founders." Since the ephemeral Soviet Republic of Hungary was the only soviet regime in 1919 that consistently tried to establish the dictatorship of the proletariat in imitation of the Bolsheviks, its short history has given rise to many interpretations. The twenty-two delegates included five members of the Organization Bureau, fourteen delegates from the clandestine organizations in Hungary, and three from the organization in Vienna. Practically alone in the possession of power, the HCP shifted toward openly Stalinist policies from the beginning of 1948.
