Abstract: Antisemitism is a problem that is prevalent throughout the world. Violence and riots have frequently occurred for many years in football games in many countries, committed by fans of a club or by hooligans. Antisemitism has also become common at games, with football clubs using antisemitic language and symbols against their rivals. Sometimes, antisemitism is used by far-right political organizations at football stadiums for propaganda purposes and as a device to incite violence. It is interesting, and puzzling, that some fans of two teams, Spurs in London, and Ajax in Amsterdam, have declared themselves “Jewish,” and adopted and displayed Jewish symbols, as a response to antisemitic attacks on their club. While it is difficult to eradicate manifestations of antisemitism, it is encouraging that various private organizations, football clubs, and local and national governmental bodies have begun to formulate rules to punish those responsible for antisemitic language and actions.
