History of the Peloponnesian War

And here is no inconsiderable exemplification of my assertion, that the migrations were the cause of there being no correspondent growth in other parts. The most powerful victims of war or faction from the rest of Hellas took refuge with the Athenians as a safe retreat; and at an early period, becoming naturalized, swelled the already large population of the city to such a height that Attica became at last too small to hold them, and they had to send out colonies to Ionia.

There is also another circumstance that contributes not a little to my conviction of the weakness of ancient times. Before the Trojan war there is no indication of any common action in Hellas,

nor indeed of the universal prevalence of the name; on the contrary, before the time of Hellen, son of Deucalion, no such appellation existed, but the country went by the names of the different tribes, in particular of the Pelasgian. It was not till Hellen and his sons grew strong in Phthiotis, and were invited as allies into the other cities, that one by one they gradually acquired from the connection the name of Hellenes; though a long time elapsed before that name could fasten itself upon all.
