Chervenkov's policies closely resembled those of the Soviet Union at the time, which earned him the nickname "Little Stalin". His rule featured harsh repression of all deviation from the party line, arbitrary suppression of culture and the arts along the lines of Socialist realism, and an isolationist foreign policy. He also became the object of a personality cult. In 1950, a collectivization campaign was launched. By early 1951, Chervenkov had expelled one in five party members, including many high officials, in his campaign for complete party discipline. Out of 460,000 members, 100,000 were expelled from the party by 1953. Although Chervenkov's personality cult model was similar to that of Stalin - various places were named after him like the Medical University in Sofia and one of the city's districts - he personally accepted it only as a necessity of the current political situation and strongly opposed any extremities.
