This dissertation examines how the United States can sustain global leadership by drawing lessons from historical case studies of Habsburg Spain and Imperial Britain. The research demonstrates that sustained global leadership requires adaptability, strategic reform, and effective management of internal and external challenges. Key findings include the importance of fiscal stability, reputation management, and the role of institutions in managing allies versus challengers. Policy recommendations emphasize maintaining internal cohesion, prioritizing strategic alliances, and leveraging democratic flexibility to navigate modern challenges. The study underscores that the U.S. must address domestic issues and adapt foreign policy to the evolving global landscape.
