Béla Kun

After attending Franz Joseph University at Kolozsvár (today Cluj-Napoca, Romania), Kun had worked as a journalist until World War I. He served in the Austro-Hungarian Army, was captured by the Imperial Russian Army in 1916, and was sent to a prisoner-of-war camp in the Ural Mountains. In Russia Kun embraced communist ideas, and in 1918 in Moscow he co-founded a Hungarian arm of the Russian Communist Party. He befriended Vladimir Lenin and fought for the Bolsheviks in the Russian Civil War.
In November 1918 Kun returned to Hungary with Soviet support and set up the Party of Communists in Hungary. Adopting Lenin's tactics, he agitated against the government of Mihály Károlyi and achieved great popularity despite being imprisoned. After his release in March 1919, Kun led a successful coup d'état, formed a Communist-Social Democratic coalition government, and proclaimed a Hungarian Soviet Republic. Though the Republic's ''de jure'' leader was Prime Minister Sándor Garbai, ''de facto'' power was held by Foreign Minister Kun, who maintained direct contact with Lenin via radiotelegraph and received orders and advice from the Kremlin.
Four months later, the new regime collapsed in the face of a military offensive by the Kingdom of Romania. Kun fled to Soviet Russia, where from 1920 he worked as a functionary in the Communist International bureaucracy as head of the Crimean Revolutionary Committee. He organised and actively participated in the Red Terror in Crimea (1920–1921), following which he participated in the 1921 March Action, a failed Communist uprising in Germany.
During the late-1930s Great Purge, Kun was accused of Trotskyism and was arrested, interrogated, tried, and executed in quick succession. In 1956, following Joseph Stalin's death and the Soviet Union's de-Stalinization under Nikita Khrushchev, he was posthumously rehabilitated by the Soviet leadership. Provided by Wikipedia
