Undergraduate students in most preliminary courses in international politics are introduced to realist, liberal, and constructivist approaches, supplementing this theoretical introduction with conceptual discussions of the state, international system, and/or decision-making and policy formation. By the end of their college experience, undergraduate IR majors will engage coursework more narrowly focused on an empirical outcome, such as war, economic integration, development, or migration. These advanced courses are directly linked to modern research agendas and graduate level course material, usually with few references to the theoretical paradigms taught in introductory classes. This volume seeks to bridge the gap between what is taught in early undergraduate education and what is created by scholars, uniting abstract theoretical principles with practical contemporary policy and testable empirical questions.
