During the months between February and October 1917, the power of the Provisional Government was consistently questioned by nearly all political parties. A system of 'dual power' emerged, in which the Provisional Government held nominal power, though increasingly opposed by the Petrograd Soviet, their chief adversary, controlled by the Mensheviks and Socialist Revolutionaries (both democratic socialist parties politically to the right of the Bolsheviks). The Soviet chose not to force further changes in government due to the belief that the February Revolution was Russia's "crowing" overthrow of the bourgeois. The Soviet also believed that the new Provisional Government would be tasked with implementing democratic reforms and pave the way for a proletarian revolution. Though the creation of a government not based on the dictatorship of the proletariat in any form, was viewed as a "retrograde step" in Vladmir Lenin's April Theses. However, the Provisional Government still remained an overwhelmingly powerful governing body.
