What is "nabu-mukin-zeri"

Nabû-mukin-zēri, inscribed AG-DU-NUMUN, also known as Mukin-zēri, was the king of Babylon 731–729 BC. The Ptolemaic Canon gives his name as Χινζηρος. His reign was brought to its eventual end by the capture of the stronghold of Šapia by the forces of the Assyrian king Tukultī-apil-Ešarra III (745–727 BC). The chief of the Chaldean Amukanu tribe in southern Babylonia, he took advantage of the instability which attended the revolt against Nabû-nādin-zēri and deposed its leader, Nabû-šuma-ukîn II.
