The Communist Manifesto , Marx and Engels' revolutionary 1848 summons to the working classes, is one of the most influential political theories ever formulated. After four years of collaboration, the authors produced this incisive account of their idea of Communism, in which they envisage a society without classes, private property, or a state. They argue that increasing exploitation of industrial workers will eventually lead to a revolution in which capitalism is overthrown. Their vision transformed the world irrevocably, and remains relevant as a depiction of global capitalism today.
