Aà ¡arÃÂd-apil-Ekur, inscribed <sup>m</sup>a-à ¡Ã¡-rid-<small>A-ÃÂ.KUR</small> or <sup>m</sup><small>SAG.KAL-DUMU.Uà  -ÃÂ.KUR</small> and variants (meaning "the heir of the Ekur is foremost"), was the son and successor of Tukultë-apil-Eà ¡arra I as king of the Middle Assyrian Empire, reigning for just two years, 1076/5âÂÂ1074 BC, during the turmoil that engulfed the end of that lengthy reign, and he was the 88th king to appear on the Assyrian King List. His reign marked the elevation of the office of ummânu, âÂÂroyal scribe,â and he was the first to have this recorded next to the kingâÂÂs name on the Synchronistic King List, possibly identifying the contemporary redactor of this list.
According to an early reading of the Synchronistic King List, he was a contemporary of the Babylonian king Itti-Marduk-balÃÂá¹Âu, c. 1140âÂÂ1132 BC, where this monarch had perhaps been relocated to follow Marduk-nÃÂdin-aḫḫÃÂ, c. 1099-1082 BC. This part of the cuneiform text is now lost or disproven. Current theories of chronological succession suggest Marduk-à ¡ÃÂpik-zÃÂri, c. 1082âÂÂ1069 BC, may have been his Babylonian counterpart, with Rowton suggesting synchronizing the two-year reign of Aà ¡arÃÂd-apil-Ekur with this king's 5th and 6th years.
There are no royal inscriptions known from his reign and he appears only in later king lists and in an eponym list. He was succeeded by his brother Aà ¡à ¡ur-bel-kala, then his nephew Eriba-Adad II, then his other brother à  amà ¡i-Adad IV.
