Elections to the Russian Constituent Assembly were held on 25 November 1917, although some districts had polling on alternate days, around two months after they were originally meant to occur, having been organized as a result of events in the February Revolution. They are generally recognised to be the first free elections in Russian history. The dissolution of the Constituent Assembly was also approved by the Left Socialist Revolutionaries and anarchists; both groups were in favour of a more extensive democracy.

The October Revolution, also known as the Great October Socialist Revolution, October coup, or Bolshevik coup was a revolution in Russia led by the Bolshevik Party of Vladimir Lenin that was a key moment in the larger Russian Revolution of 1917–1923. It was the second revolutionary change of government in Russia in 1917. It took place through an armed insurrection in Petrograd on 7 November 1917 [O.S. 25 October]. It was the precipitating event of the Russian Civil War.
