Mátyás Rákosi
Rákosi was finally forced to resign in July 1956 and leave for the Soviet Union , replaced by his second-in-command Ernő Gerő . The Hungarian Revolution of 1956 occurred barely three months later as a result of the abuses of Rákosi's system , and his former rival Imre Nagy would become a dominant figure in the Revolution .
