The communist manifesto has been recognized as one of the most influential political manuscripts in the world. It presents an analytical approach to the class struggle (historical and present) and the problems of capitalism, rather than a prediction of the potential future forms of communism. The book contains the theories of Marx and Engels on the nature of society and politics, which in its own words: "The history of all society so far exists is the story of class struggles". It also briefly presents its ideas for how the capitalist society of the time would eventually be replaced by socialism and, finally, by communism.
