Proletarian internationalism (or international socialism) is the Marxist principle that working-class revolutions are fundamentally global, not national, struggles. It posits that because capitalism is an interconnected global system, workers worldwide share identical interests and must unite across borders to achieve liberation.Core BeliefsUnited Class Struggle: The working class (proletariat) has more in common with workers in other countries than with the capitalist class (bourgeoisie) of its own nation.Global Overthrow: The ultimate goal is the dismantling of capitalism globally rather than reforming it within individual countries.Mutual Aid: Workers' movements are expected to actively support liberation and socialist struggles in other countries (often summarized by the historical rallying cry: "Workers of the world, unite!").Historical ContextHistorically, the concept guided the formation of worldwide communist organizations (like the First, Second, and Third [Comintern] Internationals) to coordinate global efforts. During the Cold War, it was used by socialist states—such as the Soviet Union and Cuba—to justify providing military, material, and political support to anti-colonial and communist movements in the Global South.Proletarian vs. Bourgeois NationalismUnlike bourgeois nationalism, which promotes competition between nations for resources and geopolitical dominance, proletarian internationalism rejects imperialist expansion and nationalism. Socialists argue that workers must reject nationalist or xenophobic tendencies, which are viewed as tools used by the ruling class to divide workers and distract them from their shared economic exploitation.To explore the primary texts and historical documents associated with this concept, visit the Marxists Internet Archive.
