Partition of the Mountain ASSR began shortly after it was formed, and its Chechen District was separated on November 30, 1922 as Chechen Autonomous Oblast. On July 7, 1924, the remains of the Mountain ASSR were split into North Ossetian Autonomous Oblast and Ingush Autonomous Oblast. On January 15, 1934, Chechen and Ingush Autonomous Oblasts were joined into Checheno-Ingush Autonomous Oblast, which was elevated in status to that of an ASSR (Checheno-Ingush ASSR) on December 5, 1936.
