On the 20th of Tebet, or December, B.C. 681, Sennacherib was murdered by his two sons, and the Babylonians saw in the deed the punishment of his crimes. His favourite son, Esar-haddon, was at the time commanding the Assyrian army in a war against Erimenas of Ararat. As soon as the news of the murder reached him, he determined to dispute the crown with his brothers, and accordingly marched against them. They were in no position to resist him, and after holding Nineveh for forty-two days, fled to the court of the Armenian king. Esar-haddon followed, and a battle fought near Malatiyeh, on the 12th of Iyyar, or April, B.C. 680, decided the fate of the empire. The veterans of Esar-haddon utterly defeated the conspirators and their Armenian allies, and at the close of the day he was saluted as king. He then returned to Nineveh, and on the 8th of Sivan, or May, formally ascended the throne.
Esar-haddon proved himself to be not only one of the best generals Assyria ever produced, but a great administrator as well. He endeavoured to cement his empire together by a policy of reconciliation, and one of his first actions was to rebuild Babylon, to bring back to it its gods and people, and to make it one of the royal residences. Bel acknowledged him as his adopted son, and for twelve years Esar-haddon ruled over western Asia by right divine as well as by the right of conquest.
But a terrible danger menaced Assyria and the rest of the civilised Oriental world at the very beginning of his reign. Sennacherib’s conquest of Ellipi, and the wars against Ararat and Minni, had weakened the barriers which protected the Assyrian empire from the incursions of the barbarians of the north. The Gimirra or Kimmerians, the Gomer of the Old Testament, driven by the Scyths from their seats on the Dniester and the Sea of Azof, suddenly appeared on the horizon of western Asia. Swarming through the territories of the Minni to the east of Ararat, they swooped down upon the Assyrian frontier, along with other northern nations from Media, Sepharad, and Ashchenaz. While a body of Kimmerians under Teuspa marched westward, the rest of the allies, under Kastarit or Kyaxares of Karu-Kassi, attacked the fortresses which defended Assyria on the north-east. At Nineveh all was consternation, and public prayers, accompanied by fasting, were ordered to be offered
