Until 1979, Britain contended with an avowedly segregationist element in its population, with complex but significant legacies. Located on the fringes of ‘Greater Britain’ in Southern Africa, 250,000 ‘Britons’ in Rhodesia (now Zimbabwe) justified white-minority rule, and rebellion against the Crown, using transatlantic discourses of white nationalism which had a significant impact on discussions regarding race and identity in the British metropole. Through Rhodesia’s experience and the discourses white Rhodesian propagandists produced, we can grasp the manner in which imperial nostalgia was transformed into transnational white nationalism, a discourse that continues to haunt present debates. Unravelling this must be one of the key tasks of global historians today, argues Niels Boender.
