Workers of the world, unite!
Rallying cry from The Communist Manifesto / From Wikipedia, the free encyclopedia
The political slogan "Workers of the world, unite!" is one of the rallying cries from The Communist Manifesto (1848)[1][2][3][4] by Karl Marx and Friedrich Engels (German: Proletarier aller Länder, vereinigt Euch!, literally 'Proletarians of all countries, unite!',[5] but soon popularised in English as "Workers of the world, unite! You have nothing to lose but your chains!").[5][note 1]
A variation of this phrase ("Workers of all lands, unite") is also inscribed on Marx's tombstone.[7] The essence of the slogan is that members of the working classes throughout the world should cooperate to defeat capitalism and achieve victory in the class conflict.[8]
