The Communist Manifesto, originally the Manifesto of the Communist Party (German: Manifest der Kommunistischen Partei), is an 1848 pamphlet by German philosophers Karl Marx and Friedrich Engels. Commissioned by the Communist League and originally published in London just as the Revolutions of 1848 began to erupt, the Manifesto was later recognised as one of the world's most influential political documents. This political document explains the material conception of history and presents their theories and ideas of how in due course socialism would replace the capitalist society of the time. It discusses the relationship between the proletarians and the bourgeoisie, the Communists and the proletarians and the Communists and other opposition parties.
