Following the Mongolian Revolution of 1921, the Mongolian People's Party took control of the new Mongolian People's Republic. A 20-member commission drafted a new constitution, which was modelled on the 1918 constitution of the Russian Soviet Federative Socialist Republic; the commission was chaired by Prime Minister Balingiin Tserendorj and supervised by Turar Ryskulov from Comintern. A 90-member Great Khural was to be elected to approve the new constitution.
