Now followed years of exhausting warfare and of victory after victory, which fatally wasted the strength of Assyria. Never had the empire been so respected; never had so many nations united under one sceptre. But troubles accumulated. Mutiny in Egypt called for another expedition, which led to the capture and sacking of Thebes. Next came a war with Elam, ending in its subjection to Assyria, for the first time in history.

But with success. Assurbanipal grew arrogant in his attitude to his brother, the King of Babylon, and a fratricidal war resulted in the defeat and death of Shamash-shumukin and the capture of the rival capital. But Assyria was now near one of its recurrent periods of exhaustion, and foes were rising for a formidable attack.

IV.--Fall of Media and Chaldæa

At the very height of his apparent grandeur and prosperity Assurbanipal was attacked by Phraortes, King of the Medes, who paid for his temerity with his life, being left dead, with the greater part of his army, on the field. But the sequel was unexpected, for Cyaxares, son of the slain Mede, stubbornly continued the conflict, patiently reorganising his army, until he won a great victory over the Assyrian generals, and shut up the remnant of their forces in Nineveh.

Assurbanipal, after a reign of forty-two years, died about 625 B.C., and was succeeded by his son, Assuretililani. Against his brother and successor, Sinsharishkin, the standard of rebellion was raised by Nabopolassar, the governor of Babylon, who declared himself independent, and assumed the title of king, but his reign not long after ended with his death, in 605 B.C. Nebuchadrezzar was proclaimed king in Babylon.

His reign was long and prosperous, and, on the whole, a peaceful one. The most notable event in the career of Nebuchadrezzar II., was the capture and destruction of Jerusalem, in consequence of a revolt of Tyre and Judea. The unfortunate king, Zedekiah, saw his sons slain in his presence, and then, his eyes having been put out, he was loaded with chains, and sent to Babylon.

Nebuchadrezzar died in 562 B.C. after a reign of fifty-five years. His successors were weak rulers, and their reigns were brief and inglorious. The army was suffered to dwindle, and the dynasty founded by Nabopolassar came to an end in 555 B.C., when Labashi-marduk, the last of the line, after reigning only nine months, was murdered by Nabonidus, a native Babylonian. This usurper witnessed the rapid rise of the new Iranian power which was to destroy him and Babylon. In 553 B.C., Cyrus, a Persian general, revolted against Astyages, defeated him, and destroyed the Median Empire at one blow.

The only army that was a match for that of Cyrus was the Lydian host under King Croesus. A conflict took place between the two, ending in the defeat of the most powerful potentate of Asia Minor. But Cyrus treated Croesus with consideration, and the Lydian king is said to have become the friend of the mighty Persian. From that day neither Egypt nor Chaldæa had any chance of victory on the battlefield. Nabonidus became a mere vassal of Cyrus, and lived more or less inactively in his palace at Tima, leaving the direction of power at Babylon in the hands of his son, Bel-sharuzu.

At length the Babylonians grew weary of their king. Nabonidus had never been popular, and the discontent of the people at length called for the intervention of the suzerain. In 538 Cyrus moved against Babylon, and Nabonidus now retreated into the city with his troops, and prepared for a siege. But Cyrus, taking advantage of the time of the year when the waters were lowest, diverted the Tigris, so that his soldiers were able to enter the city without striking a blow. Nabonidus surrendered, and Belsharuzur was slain. With him perished the second Chaldæan Empire.

The sagacious conqueror did not pillage the city, and treated the citizens with clemency. Cyrus associated his son Cambyses with himself, making him King of Babylon. Nothing in Babylon was changed, and she remained what she had been since the fall of Assyria, the real capital of the regions between the Mediterranean and the Zapcos. The Persian dominion extended undisputed as far as the Isthmus of Suez. Under Cyrus took place the first return of the Jews to Jerusalem.
