The documents edited here cover the significant events in the contact, conquest, and pacification of the Nuer from 1898 to 1930. They contain some of the earliest 20th-century ethnographic descriptions of the Nuer and their Dinka and Mabaan neighbors. Together these sources provide a historical context for further understanding Evans-Pritchard's ethnography, as well as a more detailed understanding of the events that led to incorporation of the Nuer into the colonial state.
