ASAR-ADDON, or ESAR-HADDON, the son of Senacherib, succeeded his father about 712 years before the Christian æra, and united the kingdoms of Nineveh and Babylon. He rendered himself master of Syria; sent a colony to Samaria; and his generals took king Manasses, and carried him loaded with chains to Babylon. Asar Addon died after a reign of 12 years.
