Sennacherib and the Ionians
We possess few contemporary records of the Ionian expansion, even in its later stages, and the gradual hellenization of the coast-lands of southern Asia Minor is a process that, in the absence of historical documents, has largely to be inferred from later developments and by archaeological research. At least as early as the eighth century the sea-faring Greeks were known to the Assyrians, under the generic name of Ionians, as pirates and freebooters who troubled the coasts of their maritime provinces. That they should occasionally come into armed conflict with the Assyrian power was to be expected, but it has not hitherto been realized that at the beginning of the seventh century they were sufficiently numerous and powerful within the area of Assyrian control to join other adventurous and discontented elements in conducting a land campaign of some magnitude, and in defying, for a time successfully, the Assyrian forces. That they were capable of doing so may be taken as evidence of a considerable Ionian expansion eastwards at the close of the eighth and the beginning of the seventh centuries, and, though the Assyrians had little difficulty in checking the movement, it is probable that fresh conflicts of a like nature would have been recorded in the later Assyrian annals, were it not that a few years afterwards the centre of Ionian power in Western Asia Minor began to be held in check by Lydia, and later, in company with Lydia, was shaken to its foundation by the Cimmerian invaders. In fact those Ionians, whom Sennacherib met and defeated, achieved little political success, and that of a temporary character. It is possible that the effects of their cultural relations with their conquerors were more lasting.
