What is Pan-Americanism? People have been struggling with that problem for over a century. Pan-Americanism is (and has been) an amalgam of diplomatic, political, economic, and cultural projects under the umbrella of hemispheric cooperation and housed institutionally in the Pan-American Union, and later the Organization of American States. But what made Pan-Americanism exceptional? The chapters in this volume suggest that Pan-Americanism played a central and lasting role in structuring inter-American relations, because of the ways in which the movement was reinvented over time, and because the actors who shaped it often redefined and redeployed the term. Through the twentieth century, new appropriations of Pan-Americanism structured, restructured, and redefined inter-American relations. Taken together, these chapters underscore two exciting new shifts in how scholars and others have come to understand Pan-Americanism and inter-American relations. First, Pan-Americanism is increasingly understood not simply as a diplomatic, commercial, and economic forum, but a movement that has included cultural exchange. Second, researchers, political leaders, and the media in several countries have traditionally conceived of Pan-Americanism as a mechanism of US expansionism. This volume reimagines Pan-Americanism as a movement built by actors from all corners of the Americas.

The Southern Cone and the Origins of Pan America, 1888–1933 offers new perspectives on the origins of the inter-American system and the history of international cooperation in the Americas. Mark J. Petersen chronicles the story of pan-Americanism, a form of regionalism launched by the United States in the 1880s and long associated with U.S. imperial pretensions in the Western hemisphere. The story begins and ends in the Río de la Plata, with Southern Cone actors and Southern Cone agendas at the fore. Incorporating multiple strands of pan-American history, Petersen draws inspiration from interdisciplinary analysis of recent regionalisms and weaves together research from archives in Argentina, Chile, the United States, and Uruguay. The result is a nuanced and comprehensive account of how Southern Cone policy makers used pan-American cooperation as a vehicle for various agendas—personal, national, regional, hemispheric, and global—transforming pan-Americanism from a tool of U.S. interests to a framework for multilateral cooperation that persists to this day. Petersen decenters the story of pan-Americanism and orients the conversation on pan-Americanism toward a more complete understanding of hemispheric cooperation. The book will appeal to students and scholars of inter-American relations, Latin American (especially Chile and Argentina) and U.S. history, Latin American studies, and international relations. --
