Stalinist Hungary

Initially, the Hungarian People's Republic was a socialist state headed by the Communist government of Mátyás Rákosi (r. 1947–1956), a Stalinist who was beholden to the USSR. To ensure ideological compliance within his Stalinist government, Rákosi used the ÁVH (State Protection Authority) to purge 7,000 politically dissident " Titoists " and " Trotskyists " from the Communist Party of Hungary, for being "Western agents" whose participation in the Spanish Civil War (1936–1939) interfered with Stalin's long-term plans for world Communism. Among the Stalinist governments of the Eastern Bloc, the Rákosi government of the Hungarian People's Republic was most repressive of political, sexual, and religious minorities.

In 1949, the Rákosi government arrested, tortured and convicted Cardinal József Mindszenty in a show trial for treason against Hungary, for collaboration with Nazi Germany in the Holocaust in Hungary – the religious persecution of Hungarian Jews, and the political persecutions of Hungarian communists and of Hungarian anti-Nazis.
