Although the game is known by many names around the world - football, futbol, Fussball, voetbal - soccer is a universal language. Throughout the past century, governments have used soccer to further their diplomatic aims through a range of actions including boycotts, carefully orchestrated displays at matches, and more. In turn, soccer organizations have leveraged their power over membership and tournament decisions to play a role in international relations. In Soccer Diplomacy, an international group of experts analyzes the relationship between soccer and diplomacy. Together, they investigate topics such as the use of soccer as a tool of nation-state - based diplomacy, soccer as a non-state actor, and the relationship between soccer and diplomatic actors in subnational, national, and transnational contexts. They also examine the sport as a conduit for representation, communication, and negotiation. Drawing on a wealth of historical examples, the contributors demonstrate that governments must frequently address soccer as part of their diplomatic affairs. They argue that this single sport - more than the Olympics, other regional multisport competitions, or even any other sport - reveals much about international relations, how states attempt to influence foreign views, and regional power dynamics.
