What is "marduk-bel-zeri"

Marduk-bēl-zēri, inscribed in cuneiform as AMAR.UTU.EN.NUMUN or ŠID.EN.[x] and meaning “ Marduk (is) lord of descendants (lit. seed)”, very speculatively ca. 790 – 780 BC, was one of the kings of Babylon during the turmoil following the Assyrian invasions of Šamši-Adad V (ca. 824 – 811 BC). He is identified on a Synchronistic King List fragment as Marduk-[bēl]-x, which gives his place in the sequence and reigned around the beginning of the 8th century. He was a rather obscure monarch and the penultimate predecessor of Erība-Marduk who was to restore order after years of chaos.
