Plekhanov was extremely hostile to the Bolshevik Party headed by V.I. Lenin and was the top leader of the tiny Yedinstvo group, which published a newspaper by the same name. He criticized Lenin's revolutionary April Theses as "ravings" and called Lenin himself an "alchemist of revolution" for his seeming willingness to leap over the stage of capitalist development in agrarian Russia in advocating socialist revolution. Plekhanov lent support to the idea that Lenin was a "German agent" and urged the Provisional Government of Alexander Kerensky to take severe repressive measures against the Bolshevik organization to halt its political machinations.
