This book offers an assessment of the ongoing transformation of hegemonic order and its domestic and international politics. The current international order is in crisis. Under the Trump administration, the USA has ceased to unequivocally support the institutions it helped to foster. China’s power surge, contestation by smaller states, and the West’s internal struggle with populism and economic discontent have undermined the liberal order from outside and from within. While the diagnosis of a crisis is hardly new, its sources, scope, and underlying politics are still up for debate. Our reading of hegemony diverges from a static concept, toward a focus on the dynamic politics of hegemonic ordering. This perspective includes the domestic support and demand for specific hegemonic goods, the contestation and backing by other actors within distinct layers of hegemonic orders, and the underlying bargaining between the hegemon and subordinate actors. The case studies in this book thus investigate hegemonic politics across regimes (e.g., trade and security), regions (e.g., Asia, Europe, and Global South), and actors (e.g., major powers and smaller states).
