The cattle-keeping Nilotes need little introduction here. This essay focuses on the Nuer, Dinka, Atuot, and Mandari of the Southern Sudan, concerning each of whom there is a substantial and easily accessible literature, while making passing reference to the closely related Anuak of the Southern Sudan and the more distantly related Pokot and Maasai of East Africa. The Nuer and Dinka in particular are well known to all students of anthropology.[Note 1] What does perhaps require some explanation is their being taken together as ‘the cattle-keeping Nilotes’. The million or so people who are referred to by the names.
