Mar-biti-apla-usur
Mār-bīti-apla-uṣur, inscribed on contemporary inscriptions on Lorestān bronze arrowheads or in the "Dynastic Chronicle", means “O Marbīti, protect the heir.” Marbīti was a deity associated with Dēr with a sanctuary in Borsippa. Mārbītiaplauṣur reigned from 980 to 975 BC and was the sole king of Babylon’s short-lived seventh or "Elamite" Dynasty. He was a contemporary of Assyrian king Aššur-reš-iši II. Biography. The circumstances surrounding the fall of the previous Bazi dynasty and his ascendancy are unknown. His name was wholly Akkadian and he was described as a remote descendant  of Elam, šà.bal.bal ˹libir .˺ (Akkadian: "liplippi Elamti Labīru"), in the "Dynastic Chronicle". There are no known rulers of Elam bearing Akkadian titles, but his reign coincides with a blank period in Elamite political history. His rule endured for six years and he was buried in the palace of Sargon or “a legitimate king,” depending on the interpretation of "ina" (-) "qé.bir", suggesting an interment suitable for a rightful king. The "Eclectic Chronicle" records the month of Nisānu in his fourth year but the event is not preserved. It may be concerning the suspension of the Akitu festival due to Aramean  incursions, as this is the typical subject of the chronicle. Four bronze arrowheads from Lorestān have been recovered inscribed with his name and the royal title "šar kiššati", “king of the world.” They were held as part of the Foroughi collection in Tehran.
