In B.C. 334 Alexander the Great crossed the Hellespont, and within a year, by his energy and ability to use the new army-machine which he had inherited, had conquered western Asia Minor as far as the Halys, and passed on leaving it his own. This date marks an issue more changeful to Asia Minor than the conquest of Cyrus. For though no monuments throw light on the story of the next two centuries, the system of government was now initiated which in due time was to result in the Hellenising of the interior. Cities were founded with Greek names, and the Greek speech gradually made its way, through Greek-speaking princes and governors, as the official language. The change worked very slowly, but it was profound in the issue, as we shall see. At first the states maintained their old customs and native dialects without appreciable difference, except in the vigour of the new government, but in the course of two or three centuries Greek language and Greek culture, even to some extent Greek thought and religious ideas, had permeated widely among the upper-class natives of the interior. The struggles of Alexander’s successors, who had inherited from him the empire, are matters of common history. The Seleucids reunited, though in futile manner, the formerly Hittite regions in the north of Syria and Cilicia, and for a time gained some ascendency in Asia Minor, until defeated in 191 B.C. and driven back beyond the Taurus, where for another century they retained a sphere of influence. But of greater interest to us is the survival of local power in Cappadocia, under the dynasty of Ariarthes, which had come to the fore in the last century of Persian domination. This state, at first with incessant warfare, and then by means of tribute to the Seleucids, maintained in effect a form of local independence which survived even down to the Roman occupation and beyond. Another state that retained its freedom and local princes throughout this time was Bithynia, on the tract opposite Constantinople, but this is a region outside the boundaries of our story.
