The Assyrian monuments throw but little light on the circumstances which led to the assassination of Sennacherib; and we are reduced to conjecture the causes of so strange an event. Our various sources of information make it clear that he had a large family of sons. The eldest of them, Asshurinadi-su, had been entrusted by Sennacherib with the government of Babylon and might reasonably have expected to succeed him on the throne of Assyria; but it is probable that he died before his father, either by a natural death, or by violence, during one of the many Babylonian revolts. It may be suspected that Sennacherib had a second son, of whose name Nergal was the first element; and it is certain that he had three others, Adrammelech (or Ardumuzanes), Sharezer, and Esar-haddon. Perhaps, upon the death of Asshur-inadi-su, disputes arose about the succession. Adrammelech and Sharezer, anxious to obtain the throne for themselves, plotted against the life of their father, and having slain him in a temple as he was worshipping, proceeded further to remove their brother Nergilus, who claimed the crown and wore it for a brief space after Sennacherib’s death. Having murdered him, they expected to obtain the throne without further difficulty; but Esar-haddon, who at the time commanded the army which watched the Armenian frontier, now came forward, assumed the title of King, and prepared to march upon Nineveh. It was winter, and the inclemency of the weather precluded immediate movement. For some months probably the two assassins were recognized as monarchs at the capital, while the northern army regarded Esar-haddon as the rightful successor of his father. Thus died the great Sennacherib, a victim to the ambition of his sons.

It was a sad end to a reign which, on the whole, had been so glorious; and it was a sign that the empire was now verging on that decline which sooner or later overtakes all kingdoms, and indeed all things sublunary. Against plots without, arising from the ambition of subjects who see, or think they see, at any particular juncture an opportunity of seizing the great prize of supreme dominion, it is impossible, even in the most vigorous empire, to provide any complete security. But during the period of vigor, harmony within the palace, and confidence in each other inspires and unites all the members of the royal house. When discord has once entered inside the gates, when the family no longer holds together, when suspicion and jealousy have replaced the trust and affection of a happier time, the empire has passed into the declining stage, and has already begun the descent which conducts, by quick or slow degrees, to destruction. The murder of Sennacherib, if it was, as perhaps it was, a judgment on the individual, was, at least equally, a judgment on the nation. When, in an absolute monarchy, the palace becomes the scene of the worst crimes, the doom of the kingdom is sealed—it totters to its fall—and requires but a touch from without to collapse into a heap of ruins.

Esar-haddon, the son and successor of Sennacherib, is proved by the Assyrian Canon, to have ascended the throne of Assyria in B.C. 681—the year immediately previous to that which the Canon of Ptolemy makes his first year in Babylon, viz., B.C. 680. He was succeeded by his son Asshur-bani-pal, or Sardanapalus, in B.C. 668, and thus held the crown no more than thirteen years. Esar-haddon’s inscriptions show that he was engaged for some time after his accession in a war with his half-brothers, who, at the head of a large body of troops, disputed his right to the crown. Esar-haddon marched from the Armenian frontier, where (as already observed) he was stationed at the time of his father’s death, against this army, defeated it in the country of Khanirabbat (north-west of Nineveh), and proceeding to the capital, was universally acknowledged king. According to Abydenus, Adrammelech fell in the battle; but better authorities state that both he and his brother, Sharezer, escaped into Armenia, where they were kindly treated by the reigning monarch, who gave them lands, which long continued in the possession of their posterity.

The chief record which we possess of Esar-haddon is a cylinder inscription, existing in duplicate, which describes about nine campaigns, and may probably have been composed in or about his tenth year. A memorial which he set up at the mouth of the Nahr-el-Kolb, and a cylinder of his son’s, add some important information with respect to the latter part of his reign. One or two notices in the Old Testament connect him with the history of the Jews. And Abydenus, besides the passage already quoted, has an allusion to some of his foreign conquests. Such are the chief materials from which the modern inquirer has to reconstruct the history of this great king.

It appears that the first expedition of Esar-haddon was into Phoenicia. Abdi-Milkut king of Sidon, and Sandu-arra king of the adjoining part of Lebanon, had formed an alliance and revolted from the Assyrians, probably during the troubles which ensued on Sennacherib’s death. Esar-haddon attacked Sidon first, and soon took the city; but Aladi-Milkut made his escape to an island—Aradus or Cyprus—where, perhaps, he thought himself secure. Esar-haddon, however, determined on pursuit. He traversed the sea “like a fish,” and made Abdi-Milkut prisoner; after which he turned his arms against Sandu-arra, attacked him in the fastnesses of his mountains, defeated his troops, and possessed himself of his person. The rebellion of the two captive kings was punished by their execution; the walls of Sidon were destroyed; its inhabitants, and those of the whole tract of coast in the neighborhood, were carried off into Assyria, and thence scattered among the provinces; a new town was built, which was named after Esarhaddon, and was intended to take the place of Sidon as the chief city of these parts; and colonists were brought from Chaldaea and Susiana to occupy the new capital and the adjoining region. An Assyrian governor was appointed to administer the conquered province.

Esar-haddon’s next campaign seems to have been in Armenia. He took a city called Arza**, which, he says, was in the neighborhood of Muzr, and carried off the inhabitants, together with a number of mountain animals, placing the former in a position “beyond the eastern gate of Nineveh.” At the same time he received the submission of Tiuspa the Cimmerian.

His third campaign was in Cilicia and the adjoining regions. The Cilicians, whom Sennacherib had so recently subdued, reasserted their independence at his death, and allied themselves with the Tibareni, or people of Tubal, who possess at the high mountain tract about the junction of Amaans and Taurus. Esar-haddon inflicted a defeat on the Cilicians, and then invaded the mountain region, where he took twenty-one towns and a larger number of villages, all of which he plundered and burnt. The inhabitants he carried away captive, as usual but he made no attempt to hold the ravaged districts by means of new cities or fresh colonists.

This expedition was followed by one or two petty wars in the north-west and the north-east after which Esar-haddon, probably about his sixth year B.C. 675, made an expedition into Chaldaea. It appears that a son of Merodach-Baladan, Nebo-zirzi-sidi by name, had re-established himself on the Chaldaean coast, by the help of the Susianians; while his brother, Nahid-Marduk, had thought it more prudent to court the favor of the great Assyrian monarch, and had quitted his refuge in Susiana to present himself before Esar-haddon’s foot-stool at Nineveh. This judicious step had all the success that he could have expected or desired. Esar-haddon, having conquered the ill-judging Nebo-zirzi-sidi, made over to the more clear-sighted Nahid-Marduk the whole of the maritime region that had been ruled by his brother. At the same time the Assyrian monarch deposed a Chaldaean prince who had established his authority over a small town in the neighborhood of Babylon, and set up another in his place, thus pursuing the same system of division in Babylonia which we shall hereafter find that he pursued in Egypt.

Esar-haddon after this was engaged in a war with Edom. He there took a city which bore the same name as the country—a city previously, he tells us, taken by his father—and transported the inhabitants into Assyria, at the same time carrying off certain images of the Edomite gods. Hereupon the king, who was named Hazael, sent an embassy to Nineveh, to make submission and offer presents, while at the same time he supplicated Isar-haddon to restore his gods and allow them to be conveyed back to their own proper country. Esarhaddon granted the request, and restored the images to the envoy; but as a compensation for this boon, he demanded an increase of the annual tribute, which was augmented in consequence by sixty-five camels. He also nominated to the Edomite throne, either in succession or in joint sovereignty, a female named Tabua, who had been born and brought up in his own palace.

The expedition next mentioned on Esar-haddon’s principal cylinder is one presenting some difficulty. The scene of it is a country called Bazu, which is said to be “remote, on the extreme confines of the earth, on the other side of the desert.” It was reached by traversing it hundred and forty farsakhs (490 miles) of sandy desert, then twenty farsakhs (70 miles) of fertile land, and beyond that a stony region. None of the kings of Assyria, down to the time of Esar-haddon, had ever penetrated so far. Bazu lay beyond Khazu, which was the name of the stony tract, and Bazu had for its chief town a city called Yedih, which was under the rule of a king named Laile. It is thought, from the combinaqon of these names, and from the general description of the region—of its remoteness and of the way in which it was reached—that it was probably the district of Arabia beyond Nedjif which lies along the Jebel Shammer, and corresponds closely with the modern Arab kingdom of Hira. Esar-haddon boasts that he marched into the middle of the territory, that he slew eight of its sovereigns, and carried into Assyria their gods, their treasures, and their subjects; and that, though Laile escaped him, he too lost his gods, which were seized and conveyed to Nineveh. Then Laile, like the Idumaean monarch above mentioned, felt it necessary to humble himself. He went in person to the Assyrian capital, prostrated himself before the royal footstool, and entreated for the restoration of his gods; which Esar-haddon consented to give back, but solely on the condition that Laile became thenceforth one of his tributaries.
