What is "judenklub"

Judenklub is a derogatory, antisemitic term used throughout the Nazi era in Germany and Austria, applied to association football clubs with strong Jewish heritage and connections. Some of the most prominent clubs referred to in such a way by the Nazis were FC Bayern Munich, FK Austria Wien, Eintracht Frankfurt and FSV Frankfurt.

In more recent times the term has occasionally also been used in the German-language press when reporting on antisemitic chants and attacks by rival fan groups on non-German clubs like Tottenham Hotspur and Ajax Amsterdam who have a Jewish heritage or connection.
