write a pamphlet explaining the principles of communism. This became the Manifesto of the Communist Party, better known as The Communist Manifesto. It was first published on 21 February 1848 and ends with the world-famous phrase: "Let the ruling classes tremble at a Communistic revolution. The proletariat have nothing to lose but their chains. They have a world to win. Working Men of All Countries, Unite!" Engels's mother wrote in a letter to him of her concerns, commenting that he had "really gone too far" and "begged" him "to proceed no further".
