International Relations and Comparative Politics

Both the political science fields of International Relations (IR) and Comparative Politics (CP) developed around a scholarly concern with the nature of the state. IR focused on the nature, sources, and dynamics of inter-state interaction, while CP delved into the structure, functioning, and development of the state itself. The natural synergies between these two lines of scholarly inquiry found expression in the works of classical and neo-classical realists, liberals, and Marxists, all of whom, to varying degrees and in varied ways, recognized that the line dividing domestic and international politics was not hermetically sealed. As processes of economic globalization, on the one hand, and the globalization of the state system, on the other, have expanded the realm of political and economic interaction, the need for greater cross-fertilization between IR and CP has become even more evident. The global expansion of the interstate system has incorporated non-European societies into world politics and increased the salience of cultural and religious variables. These dynamics suggest that a study of cultures, religions, and histories, which shape the world views of states and peoples, is therefore necessary before assessments can be made about how individual states may respond to varied global pressures in their domestic and foreign policy choices.
