You may remember that the Greeks, at the end of the Peloponnesian War, had found out that Sparta was the strongest city in the whole country; for, although the Athenians managed to drive the Spartans out of their city, they were still forced to recognize them as the leaders of all Greece.

The Spartans were proud of having reached such a position, and were eager to maintain it at any cost. They therefore kept all the Greek towns under their orders, and were delighted to think that their king, Agesilaus, was one of the best generals of his day.
