Rene Gros believes that the Daju kingdom was rather primitive in its organization, being based mainly on military dominance.[14] It was only under the Tunjur that sophisticated state organization was introduced.[15] The Daju reign is not fondly remembered in Darfur; it is equated with tyranny.[1] The kings are remembered as pagans, ignorant and as raiders of the plains outside of Jebel Marra.[16] It is possible that the Daju monarchs reigned as divine kings. By drawing parallels to other divine kingships in Africa, this would mean that the king would have not shown himself in public and that he would have been ascribed to have magic abilities.[17] The title of the king was probably Bugur, a variant of the modern Daju term Buge ("sultan/chief").[18] Each king had his own palatial residence built for him.[15] After their death the Daju kings might have been buried near the Dereiba lakes, volcanic lakes at the top of Gebel Marra which served as places of pilgrimage and as oracles until the 20th century.[19]
