I introduce the concept of the global rhetorical presidency to account for a fundamental shift in U.S. presidential rhetoric and foreign policy, one that emerged at the dawn of the twentieth century. As the nation redirected impulses of westward expansion, manifest destiny, and settler colonialism to the rest of the world, U.S. presidents traveled beyond the nation's own borders to speak on the international stage. Through these acts of going global, chief executives sought to extend the United States' military, political, and psychological influence in various geopolitical regions and nation‐states, expand presidential power in foreign affairs, and elevate the United States’ image and position at home and abroad. The global rhetorical presidency also illuminates how U.S. presidents deploy the constellation and coalescence of five specific elements—body, place, image, audience, and circulation—to create and contribute to conditions of globalization, address audiences foreign and domestic, and rally international public opinion.
