The only other field in which such uncritical unquestioning loyalty is prized is the military and fans often portray themselves as an army, usually a barmy army, in the songs they sing. Unfortunately the military analogy extends to fighting. There is football hooliganism in every country where the game is played, it is merely a function of the passion that fans feel for their club, but the English were long considered rulers of the field partly because the English national side was the only international team to attract a sizeable and organised hooligan following ready to put aside their club loyalties to reassert English superiority. Despite the best efforts of the football authorities to present a clean image of the game hooliganism is far from dead although the scenes of mass fighting on the terraces that so often disfigured television coverage of football in the 1980's have become a thing of the past because of the introduction of all seater stadiums and the ongoing gentrification of football crowds. As the club represented a working class community it was natural that the fan should define their loyalty as much by those they hated as by those who joined them on the terraces.
Some cities have two teams, there are several in London.
In these cases each team's following will often have a traditional character. The most famous example of this is in Scottish football where Glasgow Rangers and Glasgow Celtic have been the clubs of the city's Protestant and Catholic communities respectively. In London the Tottenham Hotspur club from a working class area of North London has traditionally been the capital's Jewish club. Millwall represented a deprived area of South London associated with the docks and river workers and have long had the reputation of having the most fearsome fans in the capital. Such rivalries are not always local and may even have their routes in football.
