Workers of the world, unite!The political slogan "Workers of the world, unite!" is one of the rallying cries from The Communist Manifesto (1848) by Karl Marx and Friedrich Engels (Proletarier aller Länder, vereinigt Euch!, literally , but soon popularised in English as "Workers of the world, unite! You have nothing to lose but your chains!"). A variation of this phrase ("Workers of all lands, unite") is also inscribed on Marx's tombstone. 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.
World revolutionWorld revolution is the Marxist concept of overthrowing capitalism in all countries through the conscious revolutionary action of the organized working class. For theorists, these revolutions will not necessarily occur simultaneously, but where and when local conditions allow a revolutionary party to successfully replace bourgeois ownership and rule, and install a workers' state based on social ownership of the means of production.
Proletarian internationalismProletarian internationalism, sometimes referred to as international socialism, is the perception of all proletarian revolutions as being part of a single global class struggle rather than separate localized events. It is based on the theory that capitalism is a world-system and therefore the working classes of all nations must act in concert if they are to replace it with communism. Proletarian internationalism was strongly embraced by the first communist party, the Communist League, as exercised through its slogan "Proletarians of all countries, unite!", later popularized as "Workers of the world, unite!" in English literature.
CommunismCommunism (from Latin communis) is a left-wing to far-left sociopolitical, philosophical, and economic ideology within the socialist movement, whose goal is the creation of a communist society, a socioeconomic order centered around common ownership of the means of production, distribution, and exchange that allocates products to everyone in the society based on need. A communist society would entail the absence of private property and social classes, and ultimately money and the state (or nation state).
Communist InternationalThe Communist International (Comintern), also known as the Third International, was an international organization founded in 1919 that advocated world communism, and which was led and controlled by the Communist Party of the Soviet Union. The Comintern resolved at its Second Congress in 1920 to "struggle by all available means, including armed force, for the overthrow of the international bourgeoisie and the creation of an international Soviet republic as a transition stage to the complete abolition of the state".
