The Hungarian Revolution of 1956 or Hungarian Uprising of 1956 (Hungarian: 1956-os forradalom or felkelés) was a spontaneous nationwide revolt against the government of the Hungarian People's Republic and its Soviet-imposed policies, lasting from 23 October until 10 November 1956. Though leaderless when it first began, it was the first major threat to Soviet control since the USSR's forces drove out the Nazis at the end of World War II and occupied Eastern Europe. Despite the failure of the uprising, it was highly influential, and foreshadowed the downfall of the Soviet Union.[6]
