Mortal-tier (per registry strict-paternal-criterion: father Manishtushu was a mortal Akkadian king) ruler of the Akkadian Empire ~2254-2218 BCE; grandson of Sargon. The first Mesopotamian king known to have claimed divinity for himself during his own lifetime — prefixed his name with the divine determinative dingir 𒀭 in his own royal inscriptions; took the title "God of Akkad"; adopted the horned-helmet iconography traditionally reserved for deities; was officially worshipped during his lifetime. The Bassetki Statue inscription (Iraq Museum IM 77823) is the canonical-primary attestation of the self-deification narrative. The Victory Stele of Naram-Sin (Louvre Sb 4) is the canonical-iconographic reference-point for ancient-Mesopotamian royal-victory monumental art. Under Naram-Sin the Akkadian Empire reached its maximum extent. The self-divinization is a unique innovation in Mesopotamian kingship-ideology, paralleled later by the Ur III dynasty (Šulgi onward, hence the historical-political backdrop for the existing registry's Šulgi divine-paternity claim) and by Hellenistic ruler-cults.
