Commerce and Conflict

Sebastian Rosato

University of Notre Dame

February 4, 2026 12:00-1:30pm E40-496

Summary:
What is the relationship between commerce and conflict in international affairs? In this seminar, Professor Rosato will present his research that shows great powers have a powerful incentive to use force in order to establish or maintain commercial relations because commerce — trade and investment — is a source of power and security. Whether or not they act on their incentives is largely a function of the balance of military capabilities between them and their targets. The theory offers a simple explanation for the course of three multilateral great-power competitions: the Great Game (1830-1907); the Scramble for Africa (1870-1914); and the Scramble for China (1832-1945).
