This essay looks at blackness in the USSR from its contested margins. Focusing on South Africans categorized as “Coloured,” I explore dynamics of translation, solidarity, misunderstanding, and invisibility that arose when differing systems of racial classification interacted. In South Africa under segregation and apartheid, an intermediate category emerged between the dominant white minority and the subjugated black majority: Coloured. As the USSR became involved in South African anti-racist struggles, Soviet citizens did not know how to see and understand these lighter-skinned people who did not fit neatly into Soviet preconceptions about darker-skinned people of African descent. A handful of Coloured activists took on particularly prominent roles representing the plight of black South Africans for Soviet audiences, and being lighter skinned shaped their experiences of the USSR in significant ways. Traversing the realms of Soviet policy, scholarship, cultural production, and everyday interactions, we see remarkable inconsistency in how Coloureds were regarded: as invisible and also hypervisible, artificial and also real, black and also not black. This essay traces Soviet trajectories of the liminal category “Coloured” to explore the extraordinary chaos at the edges of blackness in the USSR.
