History of the Peloponnesian War

The Lacedaemonians maintained their hegemony without keeping their allies tributary to them, but took care that these should have an oligarchical form of government conformably to the sole interest of Sparta; the Athenians, on the other hand, maintained theirs by taking over in course of time the ships of the allied cities, with the exception of Chios[*](Cf. 6.85.2, 7.57.4) and Lesbos,[*](Lost its independence after the revolt of 427 B.C., cf. Thuc. 3.1.) and by imposing on them all a tax of money. And so the individual resources of the Athenians available for this war became greater than those of themselves and their allies when that alliance was still unimpaired and strongest.
