Book excerpt: The Pan-American Games, begun officially in 1951 in Buenos Aires and held in every region of the western hemisphere, have become one of the largest multi-sport games in the world. 6,132 athletes from 41 countries competed in 48 sports in the 2015 Games in Toronto, Canada. The Games are simultaneously an avenue for the spread of the Olympic Movement across the Americas, a stage for competing ideologies of Pan-American unity, and an occasion for host city infrastructural stimulus and economic development. And yet until this volume, the Games have never been studied as a single entity from a scholarly viewpoint. Historicizing the Pan-American Games presents 12 original articles on the Games. Topics range from the origins of the Games in the period between the world wars, to their urban, hemispheric and cultural legacies, to the policy implications of specific Games for international sport. The entire collection is set against the shifting economic, social, political, cultural, sporting and artistic contexts of the turbulent western hemisphere. Historicizing the Pan-American Games makes a significant contribution to the literature on major games, Olympic sport and sport in the western hemisphere. This book was previously published as a special issue of The International Journal of the History of Sport.
