The Communist Manifesto, published on 21 February 1848, is one of the world's most influential political treatises. Commissioned by the Communist League and written by communist theorists Karl Marx and Friedrich Engels, it laid out the League's purposes and program. It presents an analytical approach to the class struggle (historical and present) and the problems of capitalism, but does not offer much of a prediction of communism's potential future forms.
The Communist Manifesto has been the bedrock document for most socialist and communist movements throughout the world. The concepts Marx and Engels laid out, particularly the concepts of class struggle that each man believed defined capitalism.
