The line of direct descent, which has been traced in uninterrupted succession through eight monarchs, beginning with Asshur-bel-nisi-su, here terminates; and an interval occurs which can only be roughly estimated as probably not exceeding fifty years. Another consecutive series of eight kings follows, known to us chiefly through the famous Tiglath-Pileser cylinder (which gives the succession of five of them), but completed from the combined evidence of several other documents. These monarchs, it is probable, reigned from about B.C. 1230 to B C. 1070. Bel-kudur-uzur, the first monarch of this second series, is known to us wholly through his unfortunate war with the contemporary king of Babylon. It seems that the Semitic line of kings, which the Assyrians had established in Babylon, was not content to remain very long in a subject position. In the time of Bel-kudur-uzur, Vul-baladan, the Babylonian vassal monarch, revolted; and a war followed between him and his Assyrian suzerain, which terminated in the defeat and death of the latter, who fell in a great battle, about B.C. 1210. Nin-pala-zira succeeded. It is uncertain whether he was any relation to his predecessor, but clear that he avenged him. He is called “the king who organized the country of Assyria, and established the troops of Assyria in authority.” It appears that shortly after his accession, Vul-baladan of Babylon, elated by his previous successes, made an expedition against the Assyrian capital, and a battle was fought under the walls of Asshur in which Nin-pala-zira was completely successful. The Babylonians fled, and left Assyria in peace during the remainder of the reign of this monarch. Asshur-dayan, the third king of the series, had a long and prosperous reign. He made a successful inroad into Babylonia, and returned into his own land with a rich and valuable booty. He likewise took down the temple which Shamas-Vul, the son of Ismi-Dagon, had erected to the gods Asshur and Vul at Asshur, the Assyrian capital, because it was in a ruinous condition, and required to be destroyed or rebuilt. Asshur-dayan seems to have shrunk from the task of restoring so great a work, and therefore demolished the structure which was not rebuilt for the space of sixty years from its demolition. He was succeeded upon the throne by his son Mutaggil-Nebo. Mutaggil-Nebo reigned probably from about B.C. 1170 to B.C. 1150. We are informed that “Asshur, the great Lord, aided him according to the wishes of his heart, and established him in strength in the government of Assyria.” Perhaps these expressions allude to internal troubles at the commencement of his reign, over which he was so fortunate as to triumph. We have no further particulars of this monarch.
