From the mountains of his native land Cyrus had subjugated in thirty years three great kingdoms--Media, Lydia, and Babylonia; he had conquered Asia from the shore of the Ægean Sea to the Indus, and from the brook of Egypt to the shores of the Black and Caspian Seas and the banks of the Jaxartes. None of the conquerors before him--no Pharaoh of Egypt--none of the ancient kings of Elam or Babylon, or of the restless sovereigns of Assyria, nor even the Mede Cyaxares--had achieved results which could be distantly compared with the successes of Cyrus. And he had done more than merely subdue this region; he had understood how to maintain his conquests; he was not compelled like the rulers of Assyria to begin each year a new struggle against his defeated opponents; in his unbounded empire he knew how to institute arrangements which ensured an existence of two whole centuries. Hence it would be of great service to know more precisely what his regulations were for the management of his empire. But we are almost entirely without information about them. We can only attempt to draw conclusions from certain hints supplied by tradition as to the form which Cyrus gave to his dominions. We have already remarked that the Greeks ascribed to Cyrus the foundation of excellent institutions, and placed him by the side of Lycurgus; they maintained that at the time of Cyrus the Persians were in a condition midway between slavery and freedom. Arrian observes that the Persians, with whom Cyrus deprived the Medes of the empire and subjugated the remaining nations of Asia partly by arms and partly by voluntary submission, were poor and the inhabitants of a rugged country, and obeyed regulations which made their training like that of the Spartans.[116] We can plainly see that the kingdom rested on the power and devotion of the Persians; they were the ruling tribe beside the sovereign, and in addition to the proud consciousness that they were the lords of the empire Cyrus allowed them to enjoy the fruits and advantages of dominion. The Persians were free from contributions and taxes for the empire, they had only to render military service. Xenophon tells us that in the time of Cyrus the owners of land furnished excellent horsemen, who took the field; the rest served for pay. The garrisons in the fortresses were composed of Persians who were handsomely treated.[117] The Greeks have already told us that Cyrus permitted the Persians to express their opinions freely and openly, and paid honour to those who gave good counsel, and if they assert that no one rewarded services more liberally (V. 390), these rewards would mainly fall into the hands of the Persians. From the Persians were first and chiefly elected the captains of the armies, the commanders of the contingents which the subject nations had to furnish, and the viceroys who governed the conquered provinces. Yet nearer to the king stood the six princes of the Persian tribes (the prince of the Pasargadae was the
