On 25 March 1917, Kamenev returned from Siberian exile to St. Petersburg (renamed as Petrograd in 1914). Kamenev and Central Committee members Joseph Stalin and Matvei Muranov took control of the revived Bolshevik "Pravda" and moved it to the Right. Kamenev formulated a policy of conditional support of the newly formed Russian Provisional Government and a reconciliation with the Mensheviks. After Lenin's return to Russia on 3 April 1917, Kamenev briefly resisted Lenin's anti-government April Theses, but soon fell in line and supported Lenin until September.
