Esarhaddon

Assur has given a brother, successor of Sennacherib (2 Kings
19:37; Isa. 37:38). He ascended the throne about B.C. 681.
Nothing further is recorded of him in Scripture, except that he
settled certain colonists in Samaria (Ezra 4:2). But from the
monuments it appears that he was the most powerful of all the
Assyrian monarchs. He built many temples and palaces, the most
magnificent of which was the south-west palace at Nimrud, which
is said to have been in its general design almost the same as
Solomon's palace, only much larger (1 Kings 7:1-12).

In December B.C. 681 Sennacherib was murdered by two of his
sons, who, after holding Nineveh for forty-two days, were
compelled to fly to Erimenas of Ararat, or Armenia. Their
brother Esarhaddon, who had been engaged in a campaign against
Armenia, led his army against them. They were utterly overthrown
in a battle fought April B.C. 680, near Malatiyeh, and in the
following month Esarhaddon was crowned at Nineveh. He restored
Babylon, conquered Egypt, and received tribute from Manasseh of
Judah. He died in October B.C. 668, while on the march to
suppress an Egyptian revolt, and was succeeded by his son
Assur-bani-pal, whose younger brother was made viceroy of
Babylonia.
