A summary of the events in the reign of thirty-five years of his successor, Shalmaneser III., is contained on the Black Obelisk of Nimroud, discovered by Layard and preserved in the British Museum. He conquered the whole country round Lake Van, ravaging the country "as a savage bull ravages and tramples under his feet the fertile fields." An attack on Damascus led to a terrible but indecisive battle, Benhadad, King of Syria, proving himself fully a match for the invader. But a war with Babylon, lasting for a period of two years, ended with victory for Assyria, and Shalmaneser, entering the city, went direct to the temple of E-shaggil, where he offered worship to the local gods. Memorable events followed, first in connection with Damascus, Ahab, King of Isræl, Benhadad's ally, and other confederates, had not been faithful to his suzerainty. Ahab had by treaty agreed to surrender the city of Ramoth-gilead to the Syrian monarch and had not fulfilled his pledge. He and Jehoshaphat, King of Judah, had concluded an alliance against Benhadad, who seized the disputed fortress, and the two had organised an expedition, which led to the death of Ahab in battle. Isræl lapsed once more into the position of a vassal to Benhadad, and long remained in that subjection. The last days of Shalmaneser were embittered by the revolt of his son, Assur-dain-pal, and his death occurred in 824 B.C. The kingdom was shaken by the struggle that ensued between his sons. Samsi-ramman IV., the brother of Assurdain-pal, reigned for twelve years; his son, Ramman-nirari III., had married the Babylonian princess Sammuramat, and so had secured peace. He was an energetic and capable ruler. To him at length Damascus made submission and paid tribute. But Menuas, a bold and able King of Urartu, proved himself a thorn in the side of the Assyrian king, for he delivered from the yoke of Nineveh the tribes on the borders of Lake Urmiah and all the adjacent regions. Everywhere along the Lower Zab, and on the frontier as far as the Euphrates, the Assyrian outposts were driven back by Menuas, who also overcame the Hittites and by his campaigns formed that kingdom of Van, or Armenia, which was quite equal in size to Assyria. He died shortly before the death of Ramman-nirari, in 784 B.C. His son, Argistis, spent the first few years of his reign in completing his conquests in the country north of the Araxes. He was attacked by Shalmaneser IV., son of Ramman-nirari, but defeated the Assyrians. Misfortunes accumulated for the rulers and people who had exercised so wide a sway, and the end of the Second Assyrian Empire was not far off. Syria was lost under Assur-nirari III., who was also driven from Calah by sedition in 746 B.C. He died some months later and the dynasty came to an end, and in 745 a usurper, the leader of the revolt at Calah, proclaimed himself king under the name of Tiglath-pileser III. The Second Empire had lasted rather less than a century and a half.
