Leningradskiĭ Sovet rabochikh, krestʹi︠a︡nskikh i krasnoarmeĭskikh deputatov

The Petrograd Soviet of Workers' and Soldiers' Deputies (Russian: Петроградский совет рабочих и солдатских депутатов, Petrogradsky soviet rabochih i soldatskikh deputatov) was a city council of Petrograd (Saint Petersburg), the capital of Russia at the time. For brevity, it is usually called the Petrograd Soviet (Russian: Петроградский совет, Petrogradsky soviet). This Soviet was established in March 1917 after the February Revolution as a representative body of the city's workers and soldiers, while the city already had its well-established city council, the Saint Petersburg City Duma (Central Duma). During the revolutionary days, the council tried to extend its jurisdiction nationwide as a rival power center to the Provisional Government, creating what in Soviet historiography is known as the dvoyevlastiye (dual power). Its committees were key components during the Russian Revolution (1917) and some of them led the armed revolt of the October Revolution.
