At the Sixth Conference of the Russian Social-Democratic Labor Party held in Prague in January, 1912, the Bolsheviks, under Lenin's leadership, expelled the Mensheviks, arrogated the party name and organization to themselves and elected a Central Committee under their control. They also decided to publish a legal daily newspaper in Russia which was to be the chief vehicle for spreading Bolshevik propaganda among the workers and was intended to spearhead their campaign in the forthcoming Duma elections. When the paper appeared on the streets of St. Petersburg on April 22, 1912 (old style), it bore the name which has since become world-renowned: Pravda.
This first version of Pravda was published until July 8, 1914, when it was finally suppressed. At various times, its staff and contributors included Lenin, Ol'minskij, Molotov, Zinov'ev, Kamenev, Stalin, Bubnov, Sverdlov, Bukharin and many others who later became prominent in the Soviet Government. Lenin appears to have been the dominant figure on the paper. From Cracow, safe from the reaches of the Okhrana, he guided its destinies with an iron hand. His principal assistants were Zinov'ev and Kamenev, who left Paris to join him there.
