Thus by a vigorous and dexterous use of the advantages which she gained from the peace of Antalcidas, Sparta had advanced some steps nearer than she had ever been before to a complete subjugation of Greece. If her old rival had now recovered her independence, Thebes was reduced to a state of subjection like that in which Athens had been held by the Thirty. Within the peninsula the hostility of Argos was counterpoised by the attachment of the newly-restored Corinthian oligarchy: and the fate of Mantinea and of Phlius struck the smaller states with awe. The acquisition of Olynthus raised her reputation no less than it immediately strengthened her power. To one who considers the dangers — at this time completely veiled from human foresight — which really impended over the liberty of Greece, the establishment of the Spartan dominion may seem to have been, as at least the lighter evil, a desirable event. Such it would certainly have been, if it could have been effected so as not to excite irritation and alarm. But the causes which made the Spartan ascendancy generally odious, rendered it also insecure. Pleas might be found for the proceedings against Phlius, and Mantinea, and Olynthus. But the seizure of the Cadmea was so glaring an act of injustice, that even at Sparta, according to Xenophon, no attempt was made to defend it except on the score of expediency.
