Contested leadership in international relations

The articles in this special issue examine the responses to the rise of new and emerging powers including Brazil, China, India and South Africa across different regions. Rather than focus on great powers and hegemons, the contributors address the contestation between regional powers, and secondary and tertiary states. The contributors address three questions: What are the drivers of different strategic responses? What are the different regional responses to shifts in the distribution of material capabilities? What is the influence of agency and structure in contested regional orders? To address these questions, different schools are employed including realism, institutionalism, and the English school to examine state characteristics, systemic, sub-systemic, domestic constraints and opportunities, the role of ideas and shared values, and different regional governance structures.
