However unexpected the attack of the Lydians had been by the ruler of the Medes and Persians, however inconvenient the war with them, he had brought it to a rapid and prosperous decision. Though he had entertained no thought of conquests in the distant West before Croesus took up arms against him, he resolved to maintain the advantage which the war had brought him to such a surprising extent. Great as was the distance between Sardis and Pasargadae, Lydia was to be embodied in his empire, and the Ægean was to form its western boundary. His army took up winter quarters in Lydia; from Sardis he arranged in person the new government of the land, and the fate of the nations which had been subject to the Lydians. We do not know whether the Phrygians, Bithynians, and Paphlagonians submitted to the change of dominion without resistance. Æschylus represents Cyrus as subjugating Phrygia. According to Xenophon, Phrygia was reduced by Cyrus as he returned from Sardis; the Paphlagonians submitted voluntarily, like the Cilicians; this was the reason why no satraps were sent there, yet the fortresses were occupied with Persian garrisons, and the Paphlagonians and Cilicians had to pay tribute and perform service in war.[30] Cilicia had not been subject to the Lydians; ever since the irruption of the Scyths had broken the cohesion of the Assyrian power, her princes were independent, though they had paid tribute to Assurbanipal (III. 166, 178), They bore the standing title of Syennesis. More than sixty years previously Nabopolassar of Babylon and Syennesis of Cilicia had brought about peace and alliance between Cyaxares of Media and Alyattes of Lydia (V. 295). That Cilicia now voluntarily submitted to Cyrus, if it had not done so previously, can be concluded with certainty from the fact that we subsequently find kings named Syennesis at the head of Cilicia, who are bound to pay tribute to the Persian empire and render service in war.[31]
