Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win.Workingmen of all countries unite!

The bourgeoisie, in truth, is bound to fear the stupidity of the masses so long as they remain conservative, and the insight of the masses as soon as they become revolutionary.

When a great social revolution shall have mastered the results of the bourgeois epoch, the market of the world and the modern powers of production, and subjected them to the common control of the most advanced peoples, then only will human progress cease to resemble that hideous pagan idol, who would not drink the nectar but from the skulls of the slain.

The proletarians have nothing to lose but their chains. They have a world to win.

Die Proletarier dieser Welt haben nichts zu verlieren als ihre Ketten. Sie haben eine Welt zu gewinnen. Proletarier aller Länder, vereinigt euch!

Not in vain does it [the proletariat] go through the stern but steeling school of labour. It is not a question of what this or that proletarian, or even the whole proletariat, at the moment regards as its aim. It is a question of what the proletariat is, and what, in accordance with this being, it will historically be compelled to do.

When the proletariat declares the dissolution of the hitherto existing world order, it merely declares the secret of its own existence, since it is in fact the dissolution of this order. When it demands the negation of private property, it is only laying down as a principle for society what society has laid down as a principle for the proletariat, what has already been incorporated in itself without its consent as the negative result of society.
