This course will begin with a theoretical discussion of regions, regionalism, and regional organizations. Special attention will be paid to the case of regionalism and political economy in Europe and the future of the European project within the context of the Eurozone crisis. Emphasis will also be placed on the role of the European Union as a major non-state actor in the international, regional, and sub-regional systems both during and after the Cold War. Particular attention will be paid to the enlargement of the European Union and NATO eastward into the former communist sphere of influence. Other important regional and sub-regional organizations, in Asia, Africa, Latin America, and the Middle East will be analyzed.
