A Chaldean prince, Nabopolassar, set himself up in Babylonia, and Assyria was compelled to invoke the aid of the Askuza.
According to Berossus he was allied with Nabopolassar of Babylon, whose son Nebuchadrezzar married Amyitis, the daughter of the Median king (who is wrongly called Astyages).
As a matter of fact, however, Cyaxares and Nabopolassar were the conquerors of Nineveh, and the latter was the father of Nebuchadrezzar.
But Egypt was now at once confronted by the Neo-Babylonian or Chaldean Empire (under Nabopolassar), which, after annihilating Assyria with the help of the Medians, naturally claimed a right to the Mediterranean coast-lands.
In the following year he succeeded his father Nabopolassar on the Babylonian throne, days, Oct.
Nabopolassar was followed by his son Nebuchadrezzar II., whose reign of 43 years made Babylon once more the mistress of the civilized world.
Nineveh, according to Herodotus, was besieged by Cyaxares and the Medes but saved by Madyes and the Scythians some twenty or more years before the Medes in alliance with Nabopolassar, king of Babylon, finally took it, c. 606 B.C. Much conjecture has been lavished upon the varying accounts which have reached us of the capture, but it seems probable that a heavy flood or the besiegers burst the great dam and while thus emptying the moats launched a flood against the west wall on the inside and thus breached the defences.
North of the mound was a canal, which seems to have been the Libilkhegal of the inscriptions, while on the south side was the Arakhtu, "the river of Babylon," the brick quays of which were built by Nabopolassar.
Syria and the south he abandoned to Nabopolassar and his son Nebuchadrezzar; while, on the other hand, Assyria proper, east of the Tigris, the north of Mesopotamia with the town of Harran (Carrlwe) and the mountains of Armenia were annexed by the Medes.
The German excavations have shown that the Qsar mound represents both the old palace of Nabopolassar, and the new palace adjoining it built by Nebuchadrezzar, the wall of which he boasts of having completed in 15 days.
The newly formed Chaldean power at once recognized in Necho a dangerous rival and Nabopolassar sent his son Nebuchadrezzar, who overthrew the Egyptian forces at Carchemish (605).
The sudden rise of the later Babylonian empire under Nebuchadrezzar, the son of Nabopolassar, must have tended to produce so thorough an amalgamation of the Chaldaeans and Babylonians, who had theretofore been considered as two kindred branches of the same original Semite stock, that in the course of time no perceptible differences existed between them.
These aggressions after many centuries ended in the Chaldaean supremacy of Nabopolassar and his successors (c. 626 ff.), although there is no positive proof that Nabopolassar was purely Chaldaean in blood.
With the recovery of Babylonian independence under Nabopolassar a new era of architectural activity set in, and his son Nebuchadrezzar made Babylon one of the wonders of the ancient world.
