"Workers of the world, unite! You have nothing to lose but your chains!"
comes directly from Karl Marx
's Communist Manifesto
, a year in which revolutionary fervor swept Europe
Marx concludes his manifesto with this call to action
, hoping that industrial workers in Europe
), who lived and worked in appalling
conditions by any modern standards, would rise up and remove their oppressors.
Although the E2 Communist Manifesto node concludes with "Proletarians of all countries, unite!", the website of the American Communist Party, such as it is, contained a version of the CM ending with the actual title of this node.
