Abstract: This chapter explains contemporary manifestations of antisemitism in Southeast European football by analysing football fan cultures of three post-Yugoslav states: Croatia, Serbia, and especially Bosnia and Herzegovina, where several antisemitic incidents have occurred during the last decade. The geographic scope is determined by the cultural proximity of these fan cultures, allowing for a comparative analysis of region’s forms of antisemitism, as well as socialist (dis-)continuities of political antisemitism. Whilst international football governing bodies and international media readily condemned the incidents in Bosnia-Herzegovina, social media discussions amongst their football fans proved to be diametrically opposed, especially in the context of the Israeli–Palestinian conflict. The chapter examines the nature of anti-Jewish, anti-Israel, anti-Zionist, and antisemitic fan (and non-fan) practices and narratives, to extrapolate their inherent political nuances and to illustrate their transformations over the last two decades. By evaluating their significance for the wider public discourse, the chapter provides a more nuanced reflection of the issues at stake, within football and beyond.
