IR Marxism

Marxist and Neo-Marxist theories of IR reject the realist/liberal view of state conflict or cooperation; instead focusing on the economic and material aspects. It makes the assumption that the economy trumps other concerns; allowing for the elevation of class as the focus of study. Marxists view the international system as an integrated capitalist system in pursuit of capital accumulation. Thus, colonialism brought in sources for raw materials and captive markets for exports, while decolonialization brought new opportunities in the form of dependence.

A prominent derivative of Marxian thought is critical international relations theory which is the application of "critical theory" to international relations. Early critical theorists were associated with the Frankfurt School which followed Marx's concern with the conditions that allow for social change and the establishment of rational institutions. Their emphasis on the "critical" component of theory was derived significantly from their attempt to overcome the limits of positivism. Modern-day proponents such as Andrew Linklater, Robert W. Cox and Ken Booth focus on the need for human emancipation from the nation-state. Hence, it is "critical" of mainstream IR theories that tend to be both positivist and state-centric.

Further linked in with Marxist theories is dependency theory and the core–periphery model, which argue that developed countries, in their pursuit of power, appropriate developing states through international banking, security and trade agreements and unions on a formal level, and do so through the interaction of political and financial advisors, missionaries, relief aid workers, and MNCs on the informal level, in order to integrate them into the capitalist system, strategically appropriating undervalued natural resources and labor hours and fostering economic and political dependence.

Marxist theories receive little attention in the United States, where no significant socialist party has flourished. It is more common in parts of Europe and is one of the more important theoretic contributions of Latin American academia to the study of global networks.
