Sultan-Zade was a delegate to the Second World Congress of the Communist International in 1920 and was for a time one of the leading figures of the Marxist revolutionary movement in the so-called "East." Following his demotion from the leadership of the Iranian Communist Party and the Comintern in 1923, Sultan-Zada lived in the Soviet Union where he worked as a government functionary in the banking industry.
