Great efforts were made to render the army as irresistible as possible with the object of imposing an Assyrian supremacy upon the entire known world. Tiglath overran Armenia, defeated the Medes and Hittites, seized the seaports of Ph[oe]nicia and the trade routes connecting them with the centres of Assyrian commerce, and finally conquered Babylon, where in 729 B.C. he was invested with the sovereignty of 'Asia.' Two years later he died, but his successor, Shalmaneser IV, carried on the policy he had initiated. He had, however, only five years of life in which to do so, for at the end of that period the usurping general Sargon, who laid claim to be a descendant of Sargon the Great of Akkad, seized the royal power of Babylon. He was murdered in 705 B.C., and his son Sennacherib, of Biblical fame, appears to have been unable to carry on affairs with the prudence or ability of his father. He outraged the religious feelings of the people by razing to the ground the city of Babylon, because of the revolt of the citizens. The campaign he made against Hezekiah, King of Judah, was marked by a complete failure. Hezekiah had allied himself with the Philistine princes of Ascalon and Ekron, but when he saw his Egyptian allies beaten at the battle of Eltekeh he endeavoured to buy off the invaders by numerous presents, though without success. The wonderful deliverance of Jerusalem from the forces of Sennacherib, recorded in Scripture, and sung by Byron in his _Hebrew Melodies_, appears to have a good foundation in fact. It seems that the Assyrian army was attacked and almost decimated by plague, which obliged Sennacherib to return to Nineveh, but it is not likely that the phenomenon occurred in the watch of a night. Sennacherib was eventually murdered by his two sons, who, the deed accomplished, fled to Armenia. Of all the Assyrian monarchs he was perhaps the most pompous and the least fitted to rule. The great palace at Nineveh and the great wall of that city, eight miles in circumference, were built at his command.

Mansell and Co.] His son and successor, Esar-haddon, initiated his reign by sending back the sacred image of Merodach to its shrine at Babylon, which city he restored. He was solemnly declared king in the restored temple of Merodach, and during his reign both Babylonia and Assyria enjoyed quiet and contentment. War with Egypt broke out in 670 B.C., and the Egyptians were thrice defeated with heavy loss. The Assyrians entered Memphis and instituted a protectorate over part of the country. Two years later Egypt revolted, and while marching to quell the outbreak Esar-haddon died on the road--his fate resembling that of Edward I, who died while on his way to overcome the Scottish people, then in rebellion against his usurpation.
