This structure was maintained by the real anointed chiefs of the Acholi, the rwodi moo." Although they were believed to have supernatural powers, the chiefs ruled through a Council of Clan Elders, so they never ruled singlehandedly. The council's representatives could mediate issues between clans, and essentially covered both civil and criminal functions, like a Supreme Court. It was a system of governance fully integrated with their religion and cosmology. It was not until 1995 that a constitutional reform recognized such cultural leaders, but they have not been fully restored to previous powers, as so much of society has changed. In the pre-colonial era, all the Acholi believed in the same superior being, YA Latwer.

Purifications or atonement practices are still performed by Acholi elders in some communities.

They have continued to work to end the war through negotiation. Kitgum, Pader and Gulu, the three districts of the Acholi sub-region, each established peace forums for continuing discussions.
