The Nuer are one of the large people of the South of the Sudan and live in the West of the Ethiopia too. They live areas of the Nile. Nuer are victims of persecution by the Sudanese government. Nuer speak like the surrounding Dinka the Nuer-Dinka, one of the languages nilotes.

They were the object of an ethnographic study by the British Ethnologue Evans-Pritchard, in the years 1930.

Evans-Pritchard classified these people in the category of the companies without State. This company is presented indeed seemingly in the form of a " anarchy ordonnées" according to the author.

Nuers live (in the years 1930) of their cattle and of the attachment to their cattle, they are very sensitive to the seasonal variations which influence their lifestyle. This company has a simple technology (not iron, few stones, few trees), all is made starting from the cattle. There is in these company a tendency to the mutual aid and solidarity (to combat the risk of shortage for example).

The internal conflicts are alleviated by " the man with the skin of léopard" who is the only man having a particular status, he referee the conflicts and seeks the negotiation but does not have the capacity to force the individual wills.

The political structure is expressed in language chalk-lining, in fact the values of the company are expressed by the relationship which gives form to the political structure.
