https://en.wikipedia.org/wiki/1917_Russian_Constituent_Assembly_election
Elections to the Russian Constituent Assembly were held on 25 November 1917.[a] Organized as a result of events in the February Revolution, the elections took place two months after they had been originally meant to occur. They are generally recognised as the first free elections in Russian history,[1] though they did not produce a democratically elected government, as the Bolsheviks subsequently disbanded the Constituent Assembly and proceeded to rule the country as a one-party state with all opposition parties banned.[2][3][4]
