Fate had settled that a single lord was to bear sway over the tribes and nations dwelling between the Persian Gulf and the Euxine; and the arbitrament of the sword had now decided that this single lord should be Cyrus.

We may readily believe the statement of Nicolaus that the nations previously subject to the Medes vied with each other in the celerity and zeal with which they made their submission to the Persian conqueror.
Cyrus succeeded at once to the full inheritance of which he had dispossessed Astyages, and was recognized as king by all the tribes between the Halys and the desert of Khorassan.

Though we may not be able to trust implicitly the details of the war of independence which have come down to us, yet there can be no doubt that he had displayed in its course very remarkable courage and conduct.

He had intended, probably, no more than to free his country from the Median yoke; by the force of circumstances he had been led on to the destruction of the Median power, and to the establishment of a Persian Empire in its stead.
