International relations theory and European integration

Abstract:

The explicit effort to theorize about the process of European integration began within the field of international relations (IR), where neofunctionalism and intergovernmentalism long remained the dominant schools of thought. With the relaunching of the integration process in the 1980s and 1990s, however, IR scholars have begun to approach the study of the European Union using more general, and generalizable, theoretical approaches. This article examines the recent debate among realists, liberals, rational-choice institutionalists, and constructivists regarding the nature of the integration process and the EU as an international organization. Although originally posed as competing theories, the author argues, realist, liberal and institutionalist approaches show signs of convergence around a single rationalist model, with constructivism remaining as the primary rival, but less developed, approach to the study of European integration.
