The century during which these wars took place between Assyria and Babylonia, which corresponds with the period of the later Judges in Israel, is followed by an obscure interval, during which but little is known of either country. Assyria seems to have been at this time in a state of great depression. Babylonia, it may be suspected, was flourishing; but as our knowledge of its condition comes to us almost entirely through the records of the sister country, which here fail us, we can only obtain a dim and indistinct vision of the greatness now achieved by the southern kingdom. A notice of Asshur-izir-pal’s seems to imply that Babylon, during the period in question, enlarged her territories at the expense of Assyria, and another in Macrobius, makes it probable that she held communications with Egypt. Perhaps these two powers, fearing the growing strength of Assyria, united against her, and so checked for a while that development of her resources which they justly dreaded.
However, after two centuries of comparative depression, Assyria once more started forward, and Babylonia was among the first of her neighbors whom she proceeded to chastise and despoil. About the year B.C. 880 Asshur-izir-pal led an expedition to the south-east and recovered the territory which, had been occupied by the Babylonians during the period of weakness. Thirty years later, his son, the Black-Obelisk king, made the power of Assyria still more sensibly felt. Taking advantage of the circumstance that a civil war was raging in Babylonia between the legitimate monarch Merodach-sum-adin, and his young brother, he marched into the country, took a number of the towns, and having defeated and slain the pretender, was admitted into Babylon itself. From thence he proceeded to overrun Chaldaea, or the district upon the coast, which appears at this time to have been independent of Babylon, and governed by a number of petty kings. The Babylonian monarch probably admitted the suzerainty of the invader, but was not put to any tribute. The Chaldaean chiefs, however, had to submit to this indignity. The Assyrian monarch returned to his capital, having “struck terror as far as the sea.” Thus Assyrian influence was once more extended over the whole of the southern country, and Babylonia resumed her position of a secondary power, dependent on the great monarchy of the north.
