Ignoring the claims of his older brothers, an imperial council appointed Esarhaddon (Ashur-aha-iddina; 680–669) as Sennacherib’s successor. The choice is all the more difficult to explain in that Esarhaddon, unlike his father, was friendly toward the Babylonians. It can be assumed that his energetic and designing mother, Zakutu (Naqia), who came from Syria or Judah, used all her influence on his behalf to override the national party of Assyria. The theory that he was a partner in plotting the murder of his father is rather improbable; at any rate, he was able to procure the loyalty of his father’s army. His brothers had to flee to Urartu. In his inscriptions, Esarhaddon always mentions both his father and grandfather.

Defining the destruction of Babylon explicitly as punishment by the god Marduk, the new king soon ordered the reconstruction of the city. He referred to himself only as governor of Babylonia and through his policies obtained the support of the cities of Babylonia. At the beginning of his reign the Aramaean tribes were still allied with Elam against him, but Urtaku of Elam (675–664) signed a peace treaty and freed him for campaigning elsewhere. In 679 he stationed a garrison at the Egyptian border, because Egypt, under the Ethiopian king Taharqa, was planning to intervene in Syria. He put down with great severity a rebellion of the combined forces of Sidon, Tyre, and other Syrian cities. The time was ripe to attack Egypt, which was suffering under the rule of the Ethiopians and was by no means a united country. Esarhaddon’s first attempt in 674–673 miscarried. In 671 bc, however, his forces took Memphis, the Egyptian capital. Assyrian consultants were assigned to assist the princes of the 22 provinces, their main duty being the collection of tribute.

Occasional threats came from the mountainous border regions of eastern Anatolia and Iran. Pushed forward by the Scythians, the Cimmerians in northern Iran and Transcaucasia tried to gain a foothold in Syria and western Iran. Esarhaddon allied himself with the Scythian king Partatua by giving him one of his daughters in marriage. In so doing he checked the movement of the Cimmerians. Nevertheless, the apprehensions of Esarhaddon can be seen in his many offerings, supplications, and requests to the sun god. These were concerned less with his own enterprises than with the plans of enemies and vassals and the reliability of civil servants. The priestesses of Ishtar had to reassure Esarhaddon constantly by calling out to him, “Do not be afraid.” Previous kings, as far as is known, had never needed this kind of encouragement.

At home Esarhaddon was faced with serious difficulties from factions in the court. His oldest son had died early. The national party suspected his second son, Shamash-shum-ukin, of being too friendly with the Babylonians; he may also have been considered unequal to the task of kingship. His third son, Ashurbanipal, was given the succession in 672, Shamash-shum-ukin remaining crown prince of Babylonia. This arrangement caused much dissension, and some farsighted civil servants warned of disastrous effects. Nevertheless, the Assyrian nobles, priests, and city leaders were sworn to just such an adjustment of the royal line; even the vassal princes had to take very detailed oaths of allegiance to Ashurbanipal, with many curses against perjurers.

Another matter of deep concern for Esarhaddon was his failing health. He regarded eclipses of the moon as particularly alarming omens, and, in order to prevent a fatal illness from striking him at these times, he had substitute kings chosen who ruled during the three eclipses that occurred during his 12-year reign. The replacement kings died or were put to death after their brief term of office. During his off-terms Esarhaddon called himself “Mister Peasant.” This practice implied that the gods could not distinguish between the real king and a false one—quite contrary to the usual assumptions of the religion.

Esarhaddon enlarged and improved the temples in both Assyria and Babylonia. He also constructed a palace in Kalakh, using many of the picture slabs of Tiglath-pileser III. The works that remain are not on the level of those of either his predecessors or of Ashurbanipal. He died while on an expedition to put down a revolt in Egypt.
