This article examines a progressive moment under apartheid referred to retrospectively as ‘the Durban moment’ by activists. By exploring the friendship of assassinated activists Stephen Bantu Biko and Richard Turner, the paper calls for a nuanced assessment of the rich context of the emergence of Black Consciousness under apartheid, and shows how the rigid racial and ethnic categories imposed by the state could be challenged by creative and resourceful intellectuals. The paper draws on interviews, writings produced at the time, court transcripts and the secondary literature to argue that Black Consciousness was intimately linked on many levels to this progressive ‘moment’ in South Africa under apartheid, which has resonances for activists still today.
