In 668 a second Egyptian campaign was planned by the king, but before starting out, he had his son, Asshur-banipal, recognized as regent of Babylonia. This was to cause much trouble in the future, because it once more divided the now united country, and made an opportunity for old jealousies to creep in again. On the march, Esarhaddon died, leaving the future to regard him as noblest among Assyrian kings—the most just and fair-minded of his race.
Asshur-banipal who succeeded to the throne in 668 B.C., was naturally fond of learning and was a prodigious book-collector. By using that term for Assyrian days we mean of course a collector of clay tablets whereon were inscribed literary productions.
The Egyptian campaign had already opened, for it was plain that the conquests of two years before were practically lost. Sea-coast towns in Egypt submitted at once. Little opposition was encountered in the Land of the Pyramids, and Assyrian government was soon re-instated. The suspicion of the generals was awakened by the simplicity of their task and withdrawing their army, they loitered not far away. No sooner had they left than the Assyrian government, tolerated in the presence of the army, was thrown off and old forms instituted. Now it was the Egyptian's turn to be surprised when the army, supposed to be far on its homeward march, reappeared in the land. The revolt was quickly put down, and the leaders killed with as great cruelty as ever blackened Assyrian pages.
In 660 B.C. Egypt declared her independence and this was the first great loss of the Assyrian empire, soon to be followed by many more.
Probably before this Tyre had been forced to yield, and the king had sent his son and daughter to the Assyrian court as an indication of submission.
A raid was made into Media, some of its cities being taken and their inhabitants deported. For such experiences the Medes grew to hate the Assyrians with increasing fervor. Asshur-banipal was finding some difficulty in holding together the empire of his fathers, and when revolts occurred, they were put down with greatest severity.
Babylonia had maintained peace for fifteen years, but the people clung to the traditions of their early history, and harked back to a time when Babylon was the greatest city of the world. Now, except for freedom from tribute, they ranked as any other Assyrian province. Encouraged by the feelings of those under him, the prince-regent conceived the notion of stirring up all the provinces to revolt at the same time, hoping that Babylonian independence might be gained in time of confusion. He was urged on to this course, which was misguided and ill timed, with little chance for success. Its only hope lay in keeping secret the plot so far as the Assyrian king was concerned. There were, however, many who would gladly try to benefit themselves by unearthing any plan for revolt. There might also be governors of provinces sufficiently far-sighted to have nothing to do with any treasonable plot, and these could not be expected to guard such a secret.
At last the Chaldeans on the south, Palestine, some provinces of Syria and some Arabian tribes, promised help. The Babylonians were destined to learn how different was that from actually giving it. To allay any suspicions Asshurbanipal might have, an embassy of Babylonian nobles visited his court to give him assurance of his brother's loyalty. When the news came that the Babylonians had seized Ur and Uruk, the Assyrian king was much astonished. He spent some little time in complaint of his faithless brother; an inscription ran:
"At that time Shamash-shum-ukin, the faithless brother, to whom I had done good, and whom I had established as king of Babylon, and for whom I had made every possible kind of royal decoration, and had given him, and had gathered together soldiers, horses, and chariots, and had intrusted them to him, and had given him cities, fields, and woods, and the men dwelling in them, even more than my father had commanded—even he forgot that favor I had shown him, and he planned evil. Outwardly with his lips he spoke friendly things, while inwardly his heart plotted rebellion."
Asshur-banipal waited for a favorable omen before starting out to quell the rebellion, and it came at last in this way: "In those days a seer slept in the beginning of the night and dreamed a dream, thus: 'On the face of the Moon it is written: Whoever deviseth evil against Asshur-banipal, king of Asshur, makes enmity, a violent death I appoint for them. With the edge of the sword, the burning of fire, famine, and the judgment of the Pest-god, I will destroy their lives.' This I heard and trusted to the will of Sin, my lord. I gathered my army; against Shamash-Shum-ukin I directed the march."
