Citizenship has become a widely significant and hotly contested academic concept. Though the term may seem obvious, citizenship carries a range of subtle social and political meanings. This volume explores citizenship as it relates to sport, on the micro and macro level of analysis and in a variety of geo-political contexts. Citizenship is a central organizing principle of international competition such as the Olympic Games. Furthermore, sport is used to teach, symbolize and perform citizenship. While related to national identity, citizenship pertains more precisely to how citizens are legally and politically recognized by the state and how citizens engage within the nation state. This volume traces the roots of discourses on citizenship before illustrating a variety of ways in which citizenship and sport impinge upon each other in contemporary contexts. This bookw as published as a special issue of Sport in Society.
