Of all the cities of England and Scotland, Glasgow is most widely associated with sectarianism. As Bill Murray has remarked, the city is renowned for its religion, violence and football, three elements which crystallise in the uniquely bitter encounters between the city’s two major football clubs, Rangers and Celtic. The clubs are identified as ‘Protestant’ and ‘Catholic’ respectively, although, as Tom Gallagher has commented, supporters’ allegiances tend to be more tribal than doctrinal. Religion is inextricably bound up with nationalism in these sporting contests.
