Petrograd, and subsequently at a meeting of both Bolsheviks and Mensheviks in the same city. On April 14 a Petrograd City Conference of Bolsheviks was held. The conference approved Lenin's theses and made them the basis of its work. Within a short while the local organizations of the Party had also approved Lenin's theses.
