This first conquest of Chaldaea did not, however, produce any lasting results.  The fall of Babylon did not necessarily involve the subjection of the whole country, and the cities of the south showed a bold front to the foreign intruder, and remained faithful to Kadashmankharbe; on the death of the latter, some months after his defeat, they hailed as king a certain Bammanshumnadin, who by some means or other had made his escape from captivity.  Bammanshumnadin proved himself a better man than his predecessors; when Kidinkhutrutash, never dreaming, apparently, that he would meet with any serious resistance, came to claim his share of the spoil, he defeated him near Ishin, drove him out of the districts recently occupied by the Elamites, and so effectually retrieved his fortunes in this direction, that he was able to concentrate his whole attention on what was going on in the north.  The effects of his victory soon became apparent:  the nobles of Akkad and Karduniash declined to pay homage to their Assyrian governors, and, ousting them from the offices to which they had been appointed, restored Babylon to the independence which it had lost seven years previously.  Tukulti-ninip paid dearly for his incapacity to retain his conquests:  his son Assurnazirpal I. conspired with the principal officers, deposed him from the throne, and confined him in the fortified palace of Kar-Tukulti-ninip, which he had built not far from Kalakh, where he soon after contrived his assassination.  About this time Rammanshumnadin disappears, and we can only suppose that the disasters of these last years had practically annihilated the Cossaean dynasty, for Rammanshu-musur, who was a prisoner in Assyria, was chosen as his successor.  The monuments tell us nothing definite of the troubles which next befell the two kingdoms:  we seem to gather, however, that Assyria became the scene of civil wars, and that the sons of Tukulti-ninip fought for the crown among themselves.  Tukultiassurbel, who gained the upper hand at the end of six years, set Raminan-shumusur at liberty, probably with the view of purchasing the support of the Chaldaeans, but he did not succeed in restoring his country to the position it had held under Shalmaneser and Tukulti-ninip I. The history of Assyria presents a greater number of violent contrasts and extreme vicissitudes than that of any other Eastern people in the earliest times.  No sooner had the Assyrians arrived, thanks to the ceaseless efforts of five or six generations, at the very summit of their ambition, than some incompetent, or perhaps merely unfortunate, king appeared on the scene, and lost in a few years all the ground which had been gained at the cost of such tremendous exertions:  then the subject races would rebel, the neighbouring peoples would pluck up courage and reconquer the provinces which they had surrendered, till the dismembered empire gradually shrank back to its original dimensions.  As the fortunes of Babylon rose, those of Nineveh suffered a corresponding depression:  Babylon soon became so powerful that Eammanshumusur was able to adopt a patronising tone in his relations with Assur-nirari I. and Nabodainani, the descendants of Tukultiassurbel, who at one time shared the throne together.*
