Proletarian internationalism, sometimes referred to as international socialism, is a Marxist social class concept based on the view that capitalism is now a global system, and therefore the working class must act as a global class if it is to defeat it. Workers should struggle in solidarity with their fellow workers in other countries on the basis of a common class interest.
Proletarian internationalism is closely linked to Marxist goals of world revolution, to be achieved through successive or simultaneous communist revolutions in all nations. Marxist theory is that world revolution would lead to world communism, and later still, stateless communism.
Marxists regard proletarian internationalism as the antonym of bourgeois nationalism but the term has been subjected to different interpretations by various currents of Marxist thought.
