The October Revolution (commonly referred to as the Bolshevik Revolution, the October Uprising, or Red October), officially known in Soviet historiography as the Great October Socialist Revolution, was a revolution in Russia led by the Bolshevik Party of Vladimir Lenin that was instrumental in the larger Russian Revolution of 1917–1923. It took place through an armed insurrection in Petrograd on 25 October (Old Style, O.S.; 7 November, New Style or N.S.) 1917. The October Revolution had followed and capitalized on the February Revolution earlier in the year. The February Revolution had overthrown the Tsarist autocracy, resulting in a provisional government. The provisional government had taken power after being proclaimed by Grand Duke Michael, Tsar Nicholas II's younger brother, who declined to take power after the Tsar stepped down. During this time, urban workers began to organize into councils (soviets) wherein revolutionaries criticized the provisional government and its actions. After the Congress of Soviets, the new governing body, had its second session it elected members of the Bolsheviks and other left-wing groups such as the Left Socialist Revolutionaries (Left SR) to important positions within the new state of affairs. This immediately initiated the establishment of the Russian Soviet Republic. On 17 July 1918, the Tsar and his family, including his five children aged 13 to 22, were executed. The revolution was led by the Bolsheviks, who used their influence in the Petrograd Soviet to organize the armed forces. Bolshevik Red Guards forces under the Military-Revolutionary Committee began the occupation of government buildings on 25 October (O.S.; 7 November, N.S.), 1917. The following day, the Winter Palace (the seat of the Provisional government located in Petrograd, then capital of Russia) was captured.
