Both Yugoslav wars and Yugoslav basketball were conspicuous in Western media in the 1990s. While CNN transmitted scenes of horror from battlefields of Bosnia and Kosovo, several dozen professional athletes of Yugoslav background could be seen in action on U. S. sport channels. Yugoslavs, by far the most numerous among foreign players in the strongest basketball league in the world—the American professional basketball league (NBA)—sparked the audience's curiosity about their background and the peculiar Yugoslav style of basketball. The literature concerning the Yugoslav crisis and Balkan wars noted sporadic outbursts of ethnic hatred in sport arenas, but did not provide any detailed information on the otherwise important role of sport in Yugoslav history and society. Not even highly competent volumes such as Beyond Yugoslavia, which highlighted the country's culture, arts, religion, economy, and military, paid attention to what Yugoslavs called “the most important secondary issue in the world”—sport. Yet sport reveals not merely the pastimes of the Yugoslav peoples, but also the varieties of nationalism in the former Yugoslavia, including probably the most neglected of all local nationalisms: the official communist-era patriotic ideology of interethnic “brotherhood and unity.” The goal of this article is to highlight this type of nationalism manifested via state-directed sport using as a case study the most successful basketball program outside the United States.
