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 the Hungarian Soviet Republic. Though the ''de jure'' leader of the republic was prime minister Sándor Garbai, the ''de facto'' power was in the hands of foreign minister Kun, who maintained direct contact with Lenin via radiotelegraph and received direct orders and advice from the Kremlin.
The new regime collapsed four months later in the face of Romanian advance. Kun fled to Soviet Russia, where he worked as a functionary in the Communist International bureaucracy as the head of the Crimean Revolutionary Committee from 1920. 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 Great Purge of the late 1930s, Kun was accused of Trotskyism, arrested, interrogated, tried, and executed in quick succession. He was posthumously rehabilitated by Soviet leadership in 1956, following the death of Joseph Stalin and the De-Stalinization period under Nikita Khrushchev. Provided by Wikipedia
