Kazym rebellion The Kazym Rebellion (Russian: Казымское восстание ) is a revolt by the Khanty people of western Siberia against the collectivisation policies of the Soviet government in 1933. The revolt is named after the small town of Kazym in the Khanty–Mansi Autonomous Okrug. Some sources describe the events as "Kazym rebellions", listing a series of conflicts starting in 1931, with some half-hearted attempts at reconciliation from Soviet side, but culminating in forceful suppression in 1933 and repression in 1934.
