The October Revolution (Russian: Октя́брьская револю́ция, tr. Oktyabr'skaya revolyutsiya; IPA: [ɐkˈtʲabrʲskəjə rʲɪvɐˈlʲutsɨjə]), officially known in the Soviet literature as the Great October Socialist Revolution (Russian: Вели́кая Октя́брьская социалисти́ческая револю́ция, tr. Velikaya Oktyabr'skaya sotsialističeskaya revolyutsiya), and commonly referred to as Red October, the October Uprising or the Bolshevik Revolution, was a seizure of state power instrumental in the larger Russian Revolution of 1917. It took place with an armed insurrection in Petrograd traditionally dated to 25 October 1917 (by the Julian or Old Style calendar, which corresponds to 7 November 1917 in the Gregorian or New Style calendar).

It followed and capitalized on the February Revolution of the same year, which overthrew the and resulted in a provisional government after a transfer of power proclaimed by Grand Duke Michael, brother of Tsar Nicolas II, who declined to take power after the Tsar stepped down. During this time, urban workers began to organize into councils (Russian: Soviet) wherein revolutionaries criticized the provisional government and its actions. The October Revolution in Petrograd overthrew the provisional government and gave the power to the local soviets. The Bolshevik party was heavily supported by the soviets. After the Congress of Soviets, now the governing body, had its second session, it elected members of the Bolsheviks and other leftist groups such as the Left Socialist Revolutionaries to key positions within the new state of affairs. This immediately initiated the establishment of the Russian Socialist Federative Soviet Republic, the world's first self-proclaimed socialist state.
