[Video] The Bolsheviks and the War

World War One broke the 2nd International, as most of the workers' parties supported their own ruling class and the war effort. Lenin and the Bolsheviks maintained a class position, opposing the war, even after the February Revolution, when many former opponents of the war became supporters. The Bolshevik war policy became a key pillar of the party's programme as it led the working masses to victory in October 1917.
