A highly engaging introduction to the study of world politics, D'Anieri's "International Politics: Power and Purpose in Global Affairs," 6th Edition, provides students with the conceptual tools to understand international relations from multiple perspectives. The text uses the theme of power and purpose to examine five paradigms of international relations theory and connect the scholarly analysis of international politics to policy problems and contemporary affairs. Its cohesive pedagogical framework presents the study of international politics as a series of intellectual puzzles and policy problems -- helping students make the connections between theory and policy, history and the present and ideals and constraints. Case studies of real-world events engage student interests in history, policy and geography.
