A reign which began brilliantly often came to an impotent conclusion, owing to the king having failed to economise his reserves; and the generations which followed, compelled to adopt a strictly defensive attitude, vegetated in a sort of anaemic condition, until the birth-rate had brought the proportion of males up to a figure sufficiently high to provide the material for a fresh army. When Nebuchadrezzar made war upon Assurîshishî, he was still weak from the losses he had incurred during the campaign against Elam, and could not conduct his attack with the same vigour as had gained him victory on the banks of the Ulaî; in the first year he only secured a few indecisive advantages, and in the second he succumbed. Merodach-nadin-akhi was suffering from the reverses sustained by his predecessors when Tiglath-pileser provoked him to war, and though he succeeded in giving a good account of an adversary who was himself exhausted by dearly bought successes, he left to his descendants a kingdom which had been drained of its last drop of blood. The same reason which explains the decadence of Babylon shows us the cause of the periodic eclipses undergone by Assyria after each outburst of her warlike spirit. She, too, had to pay the penalty of an ambition which was out of all proportion to her resources. The mighty deeds of Shalmaneser and Tukulti-ninip were, as a natural consequence, followed by a state of complete prostration under Tukultiassurbel and Assurnîrarî: the country was now forced to pay for the glories of Assurîshishî and of Tiglath-pileser by falling into an inglorious state of languor and depression. Its kings, conscious that their rule must be necessarily precarious as long as they did not possess a larger stock of recruits to fall back on, set their wits to work to provide by various methods a more adequate reserve. While on one hand they installed native Assyrians in the more suitable towns of conquered countries, on the other they imported whole hordes of alien prisoners chosen for their strength and courage, and settled them down in districts by the banks of the Tigris and the Zab. We do not know what Eammânirâni and Shalmaneser may have done in this way, but Tiglath-pileser undoubtedly introduced thousands of the Mushku, the Urumseans, the people of Kummukh and Naîri, and his example was followed by all those of his successors whose history has come down to us. One might have expected that such an invasion of foreigners, still smarting under the sense of defeat, might have brought with it an element of discontent or rebellion; far from it, they accepted their exile as a judgment of the gods, which the gods alone had a right to reverse, and did their best to mitigate the hardness of their lot by rendering unhesitating obedience to their masters. Their grandchildren, born in the midst of Assyrians, became Assyrians themselves, and if they did not entirely divest themselves of
