Spurs fans call themselves "yids". Due to the historical support from the Jewish communities in North and East London, Tottenham once had a significant number of Jewish fans; it was estimated that around 10,000 or a third of the club's fans in the 1930s were Jewish. Due to this historical association, fans of many other clubs from the 1960s onwards have directed antisemitic chants at Spurs fans. Tottenham no longer has a greater number of Jewish fans than other major London clubs such as Arsenal (Jewish support for Arsenal started to increase in the 1930s); an estimate put the number of Jewish fans at Tottenham as at most 5%, about the same number as Arsenal, but the antisemitic chants against Tottenham fans persisted. In an attempt to draw the sting from these chants, Spurs fans (whether Jewish or not) adopted the words "yid" and "yiddo" for themselves and thereby turned a pejorative into a term of pride and belonging. There is, however, still some controversy over the use of "yid" or "yiddo".
