“We should not be surprised by this. The Spartan constitution was admirably designed to promote peace and virtue and harmony within the bounds of the state. But the Spartans had added to it an empire and a sovereignty won by force, something which Lycurgus would have regarded as quite superfluous to the well-being of a city , and it was for this reason that they lost their supremacy.” – Plutarch, Lives, the life of Agesilaus, king of Sparta
