Nabû-mukin-apli, typically inscribed <sup>d</sup><small>AG-DU-A</small>, âÂÂNabû (is) establisher of a legitimate heir,â ruled 974âÂÂ939 BC, founded BabylonâÂÂs 8th dynasty, the so-called Dynasty of E, and ruled for thirty-six years. The Synchronistic Kinglist records him as a contemporary of the Assyrian king Tiglath-Pileser II. His reign was plagued by Aramean invasions, resulting in Babylon being cut off from its agricultural hinterland for several years and consequently being unable to celebrate the new year festival.
His reign falls in the midst of the Babylonian dark age and consequently his ancient sources are meager. He is mentioned in the Eclectic Chronicle but without any surviving historical information. The Religious Chronicle provides the most detail about his reign. The Akitu festival, or New YearâÂÂs festival of Marduk and Nabû, was interrupted several times, indeed for a stretch of nine straight years, because the âÂÂAramaeans were belligerent.â Nabu's shrine is in the neighboring city of Borsippa and the festival seemed to involve the transport of cultic idols to the city of Babylon. The Kaldu (Chaldeans) migrated into Babylonia, and settled in the far southeast of Babylonia just after his reign.
A kudurru or boundary stone from Sippar (pictured), in southern Iraq, records a legal settlement, in his 25th year, of a feud over an estate in the district of the city of Sha-mamitu. It had formerly been the property of Arad-Sibitti, a provincial governor, and his cash-strapped Kassite family, the bët-Abi-Rattaà ¡, but had passed through marriage to the family of Buruà ¡a, a bow-maker. To complicate things, Arad-Sibitti had inadvertently killed Buruà ¡aâÂÂs slave with an arrow during the earlier reign of Ninurta-kudurri-uá¹£ur I, 983âÂÂ981 BC. Buruà ¡a had to pay 887 shekels to secure his title against the various liens imposed by Arad-SibittiâÂÂs creditors. The kingâÂÂs three sons are listed as witnesses to the settlement. A recently identified kudurru from the east of the Tigris in the Diyala region on the Mingatu-karëtu canal is dated to his 16th year and details the sales of two plots of land. There is another kudurru fragment but it is badly damaged and gives no useful information concerning his reign. A single unpublished economic text in the Musée d'Art et d'Histoire, Geneva, Switzerland, is dated to his reign.
His younger son, Rëmà «t-ilë, acted as à ¡atam ekurrÃÂti, overseer of the temples. He was succeeded by his other sons, firstly Ninurta-kudurri-uá¹£ur II, for 8 months, and then Mar-biti-aḫḫe-idinna for an as yet undetermined period.
