Mushezib-Marduk in Wikipedia

Mushezib-Marduk (692 BC - 689 BC), Chaldean prince chosen as King of Babylon after Nergal-ushezib. He led the Babylonian populace in revolt against Assyria and King Sennacherib in 689 BC, with the support of Elam and King Humban-nimena (which was attacked by the Babylonians and the Assyrians only years before), at the Battle of Halule. It's not clear who won this battle, since both sides claimed victory, and all rulers remained on their thrones, but it is generally agreed that the Assyrians suffered the greatest losses. Mushezib-Marduk lost his ally when the Elamite king Humban-nimena suffered a stroke later that same year, an opportunity King Sennacherib quickly seized by attacking Babylon, and eventually capturing it after a nine-month siege. To avenge the death of his son, whom the Babylonians had effectively killed when they handed him over to the Elamites in 694 BC, Sennacherib pillaged and burned Babylon, tore down its walls, and even diverted the Euphrates into the city. During the Sack of Babylon, Mushezib-Marduk was most likely murdered.
