Are there recurring historical dynamics and patterns that can help us understand today's power transitions and struggles over international order? What can we learn from the past? Are the cycles of rise and decline of power and international order set to continue? Robert Gilpin's classic work, War and Change in World Politics offers a sweeping and influential account of the rise and decline of leading states and the international orders they create. Now, some thirty years on, this volume brings together an outstanding collection of scholars to reflect on Gilpin's grand themes of power and change in world politics. The chapters engage with theoretical ideas that shape the way we think about great powers, with the latest literature on the changing US position in the global system, and with the challenges to the existing order that are being generated by China and other rising non-Western states.
