(victor), one of the greatest of the kings of Assyria, was the son of Sennacherib (2 Kings 19:37) and the grandson of Sargon, who succeeded Shalmaneser. He appears by his monuments to have been one of the most powerful, if not the most powerful, of all the Assyrian monarchs. He is the only one of them whom we find to have actually reigned at Babylon, where he built himself a palace, bricks from which have been recently recovered bearing his name. His Babylonian reign lasted thirteen years, and it was doubtless within this space of time that Manasseh king of Judah, having been seized by his captains at Jerusalem on a charge of rebellion, was brought before him at Babylon (2 Chronicles 33:11) and detained for a time as prisoner there. As a builder of great works Esar-haddon is particularly distinguished. Besides his palace at Babylon, he built at least three others in different parts of his dominions, either for himself or his sons, and thirty temples.
