 Arriving at Petrograd's Finland Station in April, Lenin gave a speech to Bolshevik supporters condemning the Provisional Government and again calling for a continent-wide European proletarian revolution.Over the following days, he spoke at Bolshevik meetings, lambasting those who wanted reconciliation with the Mensheviks and revealing his "April Theses", an outline of his plans for the Bolsheviks, which he had written on the journey from Switzerland.He publicly condemned both the Mensheviks and the Social Revolutionaries—who dominated the influential Petrograd Soviet—for supporting the Provisional Government, denouncing them as traitors to socialism.
