Ivan Stepanovich Konev (Russian: Ива́н Степа́нович Ко́нев; 28 December [Old Style 16 December] 1897 – 21 May 1973), was a Soviet military commander, who led Red Army forces on the Eastern Front during World War II, retook much of Eastern Europe from occupation by the Axis Powers, and helped in the capture of Germany's capital, Berlin.
After the war Konev was appointed head of the Soviet occupation forces in Eastern Germany and also Allied High Commissioner for Austria. In 1946 he became commander of Soviet ground forces and First Deputy Minister of Defense of the Soviet Union, replacing Zhukov. He held these posts until 1950, when he was appointed commander of the Carpathian Military District. This was considered as demotion, and was in line with Stalin's policy of relegating popular wartime commanders to obscure posts so they would not become threats to his position.[citation needed]
After Stalin's death, however, Konev returned to prominence. He became a key ally of the new Party leader, Nikita Khrushchev, being entrusted with the trial of the Stalinist police chief, Lavrenty Beria in 1953. He was again appointed First Deputy Minister of Defense and commander of Soviet ground forces, posts he held until 1956, when he was named Commander-in-Chief of the Armed Forces of the Warsaw Pact. He led the suppression of the Hungarian Revolution by Soviet armoured divisions.
