History of the Peloponnesian War

But it was chiefly in the war that arose a long time ago between the Chalcidians and the Eretrians,[*](The war for the Lelantine Plain (cf. Hdt. 5.99; Strabo, x. i. 11); usually placed in the seventh century, but by Curtius in the eighth (see Hermes, x. pp. 220 if.).) that all the rest of Hellas took sides in alliance with the one side or the other.

But different Hellenic peoples in different localities met with obstacles to their continuous growth; for example, after the Ionians had attained great prosperity, Cyrus and the Persian empire, after subduing Croesus[*](546 B.C.) and all the territory between the river Halys and the sea, made war against them and enslaved the cities on the mainland, and later on Darius, strong in the possession of the Phoenician fleet, enslaved the islands also.[*](493 B.C.)

The tyrants, moreover—whenever there were tyrants in the Hellenic cities—since they had regard for their own interests only,both as to the safety of their own persons and as to the aggrandizement of their own families, in the administration of their cities made security, so far as they possibly could, their chief aim, and so no achievement worthy ot mention was accomplished by them, except perchance by individuals in conflict with their own neighbours. So on all sides Hellas was for a long time kept from carrying out in common any notable undertaking, and also its several states from being more enterprising.
