The most left-wing and stringently internationalist delegates at the conference were organized around Lenin and the Russian Social Democrats, and known as the Zimmerwald Left. They bitterly condemned the war and what they described as the hypocritical "social-chauvinists" of the Second International, who so quickly abandoned their internationalist principles and refused to oppose the war. The Zimmerwald Left resolutions urged all socialists who were committed to the internationalist principles of socialism to struggle against the war and commit to international workers' revolution.[14]
