The country was in a state of continual disaffection, and after a few years a fresh revolt was headed by a Babylonian, Nergal-ushezib. But he ruled for little more than a year, being defeated by Sennacherib and sent in chains to Nineveh. This took place after the return of the Assyrian army from Nagitu, whither it had been conveyed by Sennacherib, across the head of the Persian Gulf, against the Chaldeans whom Merodach-baladan had settled there.[41] Sennacherib then turned his forces against Elam, and, after plundering a considerable portion of the country, he was stopped in his advance into the interior by the setting in of winter. In his absence the Chaldean Mushezib-Marduk seized the throne of Babylon, and allied himself with Elam. But the combined armies were defeated at Khalule, and after the death of Umman-menanu, the Elamite king, in 689, Sennacherib seized Babylon. Exasperated at her disaffection, he attempted to put an end for all time to her constant menace by destroying the city. He succeeded in doing an enormous amount of damage, and, by deflecting the course of the Euphrates, wiped out large areas and turned them into swamps.[42] For the last eight years of Sennacherib's reign the country was given over to a state of anarchy.

(After Weissbach.)] In 681 Sennacherib was murdered by his sons, and, after a struggle for the succession, Esarhaddon secured the throne. His first thought was to reverse completely his father's Babylonian policy, and by rebuilding the city and restoring its ancient privileges to placate the priestly party, whose support his grandfather, Sargon, had secured.[43] In 668 B.C. the statue of Marduk was restored to its shrine, and Esarhaddon's son, Shamash-shum-ukîn, was proclaimed King of Babylon. Esarhaddon sought to reconcile the military and aggressive party in his own capital by crowning Ashur-bani-pal, his eldest son, as king in Assyria. But at the same time Babylon was still taught to look upon Assyria as her suzerain, and the spirit of disaffection was only driven for the moment underground. Esarhaddon's aim had been to retain the territory already incorporated in the Assyrian empire, and, had he been able to confine his country's energies within these limits, its existence as a state might have been prolonged. But he was unable to curb the ambitions of his generals, and, in his effort to find employment for the army, he achieved the ultimate object of his father's western campaigns, the conquest of Egypt.
