Entities seeking to establish statehood have used participation in sport to bolster their claims. Kosovo is the latest entity to use this strategy. Kosovo’s quest to join the Union of European Football Associations led to a 2017 Court of Arbitration for Sport decision examining whether Kosovo was sufficiently an “independent state.” This article considers how participation in sport plays a role in establishing a broader, contextual conceptualization of statehood. This article then applies this concept to case studies, with particular attention paid to Kosovo. Finally, the article examines sport’s gradual acceptance that it must work within the broader international political and legal world.
