who said we have nothing to lose but our chains
Workers of the world, unite! The political slogan "Workers of the world, unite!" is one of the most famous rallying cries from The Communist Manifesto (1848)[1][2][3][self-published source][4][5] by Karl Marx and Friedrich Engels (German: Proletarier aller Länder vereinigt Euch!, literally "Proletarians of all countries, unite!",[6] but soon popularised in English as "Workers of the world, unite! You have nothing to lose but your chains!").[6][a] A variation of this phrase ("Workers of all lands, unite") is also inscribed on Marx's tombstone.[8] The essence of the slogan is that members of the working classes throughout the world should cooperate to achieve victory in class conflict.
