king, Sennacherib invaded Syria, established his authority over northern Palestine, reduced the rebellious Philistine city of Askelon, and then proceeded to attack the city of Ekron, to whose assistance an Egyptian army had rallied. Their combined forces were routed by Sennacherib at Altaku, and Ekron fell. Judah next occupied his attention; having captured numerous small towns and enslaved some 200,000 of the inhabitants, he proceeded to lay siege to Jerusalem. Hezekiah the king of Judah, withstood the siege for some time, but pressed by famine, he was compelled to yield and purchased the safety of his city by stripping the Temple of its treasures. Sennacherib thereupon returned to Assyria, but two years after, Hezekiah’s repudiation of his suzerainty occasioned another expedition to Palestine. The Assyrian troops first stationed themselves at Lachish, whence Sennacherib dispatched a messenger to Hezekiah to demand his instant surrender. Meanwhile Sennacherib marched westward with a view to engaging the Egyptian army lying at Pelusium, one of the frontier towns of Egypt. But a sudden catastrophe—possibly an outbreak of plague—overtook the Assyrian host, and Sennacherib returned to Nineveh. On his arrival home, he found it necessary to once more suppress rebellious Babylon, and to render his work more lasting, he completely destroyed the city (689 B.C.). Towards the end of his reign he conducted a campaign in Cilicia where he defeated the Greeks and is said to have laid the foundations of the city of Tarsus. In 681 B.C. he was murdered by his sons, and the crown eventually settled on the head of Esarhaddon (681-668 B.C.). The most striking event of his reign was the conquest of Lower Egypt (672 B.C.), but towards the end of his reign Tirhakah, the Ethiopian king of Egypt, recaptured Memphis and threatened to put an end to the Assyrian domination; his subjugation was one of the first acts of Ashur-bani-pal, the successor of Esarhaddon. Judah also became disaffected, but she was speedily reduced to submission and her king Manasseh was removed into captivity. Ashur-bani-pal succeeded Esarhaddon in 668 B.C. The work of re-establishing the Assyrian power in Egypt occupied some time and was finally accomplished by the capture of Thebes (666 B.C.). Under Ashur-bani-pal Assyria attained the height of her power both at home and abroad, and the limits of her empire were extended further than ever before. After a lengthy war, Elam was subdued, but she subsequently joined Shamash-shum-ukîn, the brother of Ashur-bani-pal, and viceroy of Babylonia, in an organized revolt against Assyria, which resulted in the defeat of Shamash-shum-ukîn, and the ultimate capture and sack of Susa the Elamite capital (_circ._ 640 B.C.).
