Всероссийское учредительное собрание
A spontaneous popular uprising in Petrograd, in response to the wartime decay of Russia's economy and morale, culminated in the February Revolution and the toppling of Nicholas II and the imperial government in March 1917. The tsarist autocracy was replaced by the Russian Provisional Government, which intended to conduct elections to the Russian Constituent Assembly and to continue fighting on the side of the Entente in World War I.
