Union of Soviet Socialist Republics

On 12 March, 1917, a revolution broke out in Russia, as a result of which the Emperor Nicholas II abdicated. A Provisional Government under Prince George Lvov was set up by the Duma, which held office until 16 May, 1917, when it was reorganized. On 6 August, 1917, a new Cabinet under Alexander Kerensky was formed. This, too, was reorganized on 8 October, and maintained itself until 7 November, 1917, when the Military Revolutionary Committee of the Petrograd Soviet seized the government authority, and handed it over the next day to the All-Russian Congress of Soviets.
