The Communist Manifesto, published in 1848 by Karl Marx and Friedrich Engels, outlines the ideology of communism, advocating for a classless society through the communal ownership of production. Marx's theory posits that human history is driven by class struggles, transitioning through stages from feudalism to capitalism, socialism, and ultimately to communism. The document emphasizes the elimination of private property, the establishment of social equality, and the rejection of democracy as it exists in capitalist societies.
