Bela Kun
Béla Kun (1886–1938), born Béla Kohn, was a Hungarian revolutionary who led the Hungarian Soviet Republic in 1919. Following the fall of the Hungarian revolution, Kun emigrated to the Soviet Union, where he worked as a functionary in the Communist International bureaucracy. During the Great Purge of the late 1930s, Kun was arrested, interrogated, tried, and executed in quick succession. He was posthumously rehabilitated in 1956, following the death of Joseph Stalin and the critical reassessment of Stalinism.
