Final answer:
The Nuer political structure is organized around kin groups and leopard-skin chiefs who mediate conflicts.
Step-by-step explanation:
According to E.E. Evans-Pritchard's ethnographic work 'The Nuer: A Description of the Modes of Livelihood and Political Institutions of a Nilotic People,' the Nuer political structure is organized around kin groups and leopard-skin chiefs. The Nuer people are fiercely independent and egalitarian, and they share resources within their kin groups. When conflicts arise, the leopard-skin chiefs, who are neutral mediators, negotiate settlements between the parties involved to prevent further violence.
