Petrograd Soviet
When the February Revolution broke out in 1917, Kerensky – together with Pavel Milyukov – was one of its most prominent leaders. As one of the Duma's most well-known speakers against the monarchy and as a lawyer and defender of many revolutionaries, Kerensky became a member of the Provisional Committee of the State Duma and was elected vice-chairman of the newly formed Petrograd Soviet. These two bodies, the Duma and the Petrograd Soviet, or – rather – their respective executive committees, soon became each other's antagonists on most matters except regarding the end of the Tsar's autocracy.
