This study offers an ethnographic portrait of the Atuot-speaking peoples of the Southern Sudan. While placing them in relation to neighboring Nilotic groups, it also provides a general description of Atuot communities. Topics examined include migration, ecology, settlement patterns and modes of production, social and religious values, and the interplay between individual experience and social convention. By focusing on a specific group of social facts, Burton develops a regional framework that includes not only the Atuot-speaking peoples but also the more numerous Nuer and Dinka populations.
