BÃÂba-aḫa-iddina, typically inscribed <sup>md</sup>BA.ÃÂ-PAB-Aà  'Bau has given me a brother', ca. 812 BC, was the 9th king of the Dynasty of E, a mixed dynasty of kings of Babylon, but probably for less than a year. He briefly succeeded Marduk-balÃÂssu-iqbi, who had been deposed by the Assyrians, a fate he was to share.
His name was traditionally the name of a second son. He may have been a paqid mÃÂtÃÂti official attested in the earlier reign, possibly from the Babylonian nobility who was the son of an otherwise unknown individual named Lidanu. This is a prebend grant from the second year of Marduk-balÃÂssu-iqbi which records him as a witness: <sup>md</sup>BA.ÃÂ-Ã Â EÃ Â-SUM-na DUMU <sup>m</sup>li-da-nu LÃÂ.PA ÃÂ.KUR.MEÃ Â.
His reign was brought to its end by the sixth campaign of the Assyrian king, à  amà ¡i-Adad V, as described in his Annals: "In Ni... I besieged [him]. By means of boring and siege machines [I c]aptured that [city]. BÃÂba-aḫa-iddina together with the standard (<sup>d</sup>urigallu)... I took away." A more detailed account of the events following this victory is provided in the Synchronistic History:
à  amà ¡i-Adad made no attempt to annex Babylonia which remained independent, though kingless for a period, but returned to Assyria where he spent his last year, according to the eponym record, "in the land." Finkel and Reade proposed a restoration of the final, broken part of the Synchronistic History to give: "Adad-nirari III king of Assyria and B[aba-aḫa-iddina king of Karduniaà ¡ towards each other], bowed and drank wine. The welf[are of their lands they established]..." They suggested that a pro-Babylonian à  ammur-amat, while acting as Assyrian regent for the boy-king Adad-nirari, may have moved to have BÃÂba-aḫa-iddina reinstated to stabilize their southern neighbor.
