The Communist Manifesto by Karl Marx and Friedrich Engels was published in London in 1848 in its original German, and two years later in English. It was commissioned by the Communist League and takes an analytical approach to the class struggle and the conflicts of capitalism. The Communist Manifesto summarizes the theories of Marx and Engels on the nature of society and politics, claiming that the history of all societies is a history of class struggles. It also touches on their ideas of how the capitalist society of the time would eventually be replaced by socialism. In the last paragraph of the Manifesto, the authors call for the forcible overthrow of all existing social conditions, which served as a call for communist revolutions around the globe.
