The Russian Provisional Government was a provisional government of the Russian Empire and Russian Republic, announced two days before and established immediately after the abdication of Nicholas II on 2 March, O.S. [15 March 1917, N.S.], during the February Revolution. The intention of the provisional government was the organization of elections to the Russian Constituent Assembly and its convention. The provisional government, led first by Prince Georgy Lvov and then by Alexander Kerensky, lasted approximately eight months, and ceased to exist when the Bolsheviks gained power in the October Revolution in October [November, N.S.] 1917.
