With a formal colour bar on British championships operating until 1948, boxing had long been a site of racial discrimination. The abolition of the sport's colour bar was recognition of the wrongness of racial exclusion and it was followed by a celebration of black fighters as local and national heroes. The sport became a rare space where black men could be spoken about, discussed, and celebrated without primary reference to their colour. However, race was never irrelevant, especially as the number of black boxers rose with wider patterns of migration. Race was thus widely discussed in boxing, although there was rarely open discussion of racism. This absence, along with black successes in the ring, masked deep levels of both structural and interpersonal prejudice. Racial differences remained accepted as common sense by white Britons. Indeed, immigration intensified racism in Britain, changing the perceived position of people of colour from exotic novelties to threats to society. Boxing is thus a reminder of the contradictory dynamics of race. Formal mechanisms of exclusion could be removed, while informal mechanisms intensified. Individuals could be celebrated, while people of colour as a group were looked down upon. Black achievements could simultaneously reinforce ideas of black inferiority.
