“Workers of the world, unite!”: Meaning and Origin Story of the Slogan
The slogan “Workers of the World, Unite!” encourages global solidarity among workers, urging them to cooperate across national and cultural boundaries to overthrow capitalism and end class oppression.
Origin and Meaning
The slogan “Workers of the world, unite!” originates from The Communist Manifesto (1848) by Karl Marx and Friedrich Engels. It epitomizes the central call for solidarity among workers globally to overcome class oppression and dismantle capitalism. Written in German as “Proletarier aller Länder, vereinigt Euch!” and later popularized in English, the phrase encourages collective action to achieve a classless society. The slogan underscores the belief that working-class unity transcends national and cultural boundaries.

Historical Background
The slogan’s adoption was driven by Marx and Engels’ ideology of proletarian internationalism, emphasizing the shared struggles of workers worldwide. Five years before The Communist Manifesto, Flora Tristan included a similar idea in her book, The Workers’ Union (1843), advocating for labor solidarity. This idea gained further traction with the founding of the International Workingmen’s Association (First International), which replaced the League of the Just’s motto, “All men are brothers,” with “Working men of all countries, unite!”
Interpretation and Layers of Meaning
The slogan carries multiple dimensions:
- Unionization: Workers should organize in unions to advocate for improved wages and working conditions.
- Class Struggle: Beyond workplace demands, the slogan urges workers to unite against capitalism itself.
- Global Solidarity: Workers of different nations have more in common with each other than with their national employers or elites.
Adoption by Revolutionary Movements
The Industrial Workers of the World (IWW) embraced the slogan during the early 20th century, incorporating it into their publications and protests. It became a rallying cry against World War I, reflecting their opposition to imperialist conflicts that pitted workers of one nation against another.
