Up to this time they had claimed the privilege of controlling the history of their country, and they had bravely striven among themselves for the supremacy over the southern states; but the revolutions which had raised each in turn to the zenith of power, had never exalted any one of them to such an eminence as to deprive its rivals of all hope of supplanting it and of enjoying the highest place. The rise of Babylon destroyed the last chance which any of them had of ever becoming the capital; the new city was so favourably situated, and possessed so much wealth and so many soldiers, while its kings displayed such tenacious energy, that its neighbours were forced to bow before it and resign themselves to the subordinate position of leading provincial towns. They gave a loyal obedience to the officers sent them from the north, and sank gradually into obscurity, the loss of their political supremacy being somewhat compensated for by the religious respect in which they were always held. Their ancient divinities--Nana, Sin, Anu, and Ra--were adopted, if we may use the term, by the Babylonians, who claimed the protection of these gods as fully as they did that of Merodach or of Nebo, and prided themselves on amply supplying all their needs. As the inhabitants of Babylon had considerable resources at their disposal, their appeal to these deities might be regarded as productive of more substantial results than the appeal of a merely local kinglet. The increase of the national wealth and the concentration, under one head, of armies hitherto owning several chiefs, enabled the rulers, not of Babylon or Larsa alone, but of the whole of Chaldaea, to offer an invincible resistance to foreign enemies, and to establish their dominion in countries where their ancestors had enjoyed merely a precarious sovereignty. Hostilities never completely ceased between Elam and Babylon; if arrested for a time, they broke out again in some frontier disturbance, at times speedily suppressed, but at others entailing violent consequences and ending in a regular war. No document furnishes us with any detailed account of these outbreaks, but it would appear that the balance of power was maintained on the whole with tolerable regularity, both kingdoms at the close of each generation finding themselves in much the same position as they had occupied at its commencement. The two empires were separated from south to north by the sea and the Tigris, the frontier leaving the river near the present village of Amara and running in the direction of the mountains. Durilu probably fell ordinarily under Chaldaean jurisdiction. Umliyash was included in the original domain of Kham-murabi, and there is no reason to believe that it was evacuated by his descendants. There is every probability that they possessed the plain east of the Tigris, comprising Nineveh and Arbela, and that the majority of the civilized peoples scattered over the lower slopes of the Kurdish mountains rendered them homage.
