Ere long, however, the yoke was thrown off, and the Assyrians established a separate monarchy of their own in the upper country, while the Chaldaean Empire was still flourishing under native monarchs of the old ethnic type in the regions nearer to the sea.

The special evidence which we possess of the co-existence side by side of these two kingdoms is furnished by a broken tablet of a considerably later date, which seems to have contained, when complete, a brief but continuous sketch of the synchronous history of Babylonia and Assyria, and of the various transactions in which the monarchs of the two countries had been engaged one with another, from the most ancient times.

This tablet has preserved to its the names of three very early Assyrian kings--Asshur-bil-nisi-su, Buzur Asshur, and Asshur-upallit, of whom the two former are recorded to have made treaties of peace with the contemporary kings of Babylon; while the last-named intervened in the domestic affair's of the country, depriving an usurping monarch of the throne, and restoring it to the legitimate claimant, who was his own relation.

Intermarriages, it appears, took place at this early date between the royal families of Assyria and Chaldaea; and Asshur-upallit, the third of the three kings, had united one of his daughters to Purna-puriyas, a Chaldaean monarch who has received notice in the preceding volume.

On the death of Purna-puriyas, Kara-khar-das, the issue of this marriage, ascended the throne; but he had not reigned long before his subjects rebelled against his authority.
