Naram-Sin, orNarām-Sîn or–Suen, inscribed incuneiform on contemporary seal impressions asdna-ra-am-dEN.ZU, had been the "waklum" (ugula, Overseer) or "Išši’ak Aššur" (énsida-šùr, Steward ofAshur) of the city-stateAssur.

He is listed as the 37th king ofAssyria on the laterAssyrian King Lists, where he is inscribedmna-ram-dEN.ZU,[i 1][i 2][i 3] or a fragmentary list where he appears as -d30.[i 4] He was named for the illustriousNaram-Sin of Akkad and took the divine determinative in his name (just like Naram-Sin's grandfather:Sargon I, who may have been named afterSargon of Akkad.) Naram-Sin should not be confused with theNaram-Sin who had ruledEshnunna for around twelve years (the successor and son, as identified on an inscription, of the long-reigningEbiq-Adad II.)[2] It is probable that Naram-Sin of Assur was, however, contemporaneous with the earlier part of Ebiq-Adad II’s reign (whose last attestation was in the Mari Eponym Chronicle B line 25 some 56 years after Naram-Sin’s inauguration.)[3]: 46 Naram-Sin of Assyria was the son and successor of the short-reigningPuzur-Ashur II, filiation preserved in his seal impression on the envelopes of the waklum-letters to his expat Anatolian-based traders at thekarumKanesh and in the later Assyrian King Lists.
The length of Naram-Sin's reign is uncertain, however; based on various excavated "limmu" (eponym) lists, the reigns of Naram-Sin and his son and successorErishum II had a combined length of 64 years.[4]: 29 The Assyrian King List records thatShamshi-Adad I, “went away to Babylonia in the time of Naram-Sin.” Shamshi-Adad I did not return until he had takenEkallatum, after which he paused for three years and then overthrew Erishum II.[5] The Mari Eponym Chronicle, which resumes the listing until the seizure of Ekallatum by Shamshi-Adad I, provides no clue as to when the succession of Erishum II had taken place. As the reign of Erishum II was prematurely ended by the conquests of Shamshi-Adad I, it is likely that Naram-Sin's reign was the greater part of the period, additionally; the broken figure on the Nassouhi King List ends on four, so perhaps Naram-Sin reigned 44 or 54 years (c. 1872 BC onward,middle chronology).[3]: 45 Despite this, there are no extant monumental inscriptions recording his activities.[6]
The following is a list of the last 27 annually-elected limmu officials listed on the extant Kültepe Eponym Lists (KEL) representing Naram-Sin's first years (ending nearly a decade before Naram-Sin's 35th year during which thekarumKanesh was destroyed c. 1837 BC, the II layer.)[4]: 29 The city-state of Assur which Naram-Sin had inherited would have been fairly wealthy as the hub of the trading network at the height of the Assur's activity and despite the destruction of the trading post at Kanesh partway through his reign, commerce apparently continued elsewhere. A gap of up to four years is apparent between the end of the KEL and the beginning of the Mari Eponym Chronicle (MEC B.)[3]: 5 There are no extant monumental inscriptions recording his activities.
