(M630) The Spartans now resolved to fit out a large naval force to operate against Athens, by whose assistance the Thebans had maintained their ground for two years. The Athenians, on their part, also fitted out a fleet, assisted by their allies, under the command of Chabrias, which defeated the Lacedæmonian fleet near Naxos, B.C. 376. This was the first great victory which Athens had gained since the Peloponnesian war, and filled her citizens with joy and confidence, and led to a material enlargement of their maritime confederacy. Phocion, who had charge of a squadron detached from the fleet of Chabrias, also sailed victorious round the Ægean, took twenty triremes, three thousand prisoners, with one hundred and ten talents in money, and annexed seventeen cities to the confederacy. Timotheus, the son of Conon, was sent with the fleet of Chabrias, to circumnavigate the Peloponnesus, and alarm the coast of Laconia. The important island of Corcyra entered into the confederation, and another Spartan fleet, under Nicolochus, was defeated, so that the Athenians became once again the masters of the sea. But having regained their ascendency, Athens became jealous of the growing power of Thebes, now mistress of Bœotia, and this jealousy, inexcusable after such reverses, was increased when Pelopidas gained a great victory over the Lacedæmonians near Tegyra, which led to the expulsion of their enemies from all parts of Bœotia, except Orchomenus, on the borders of Phocis. That territory was now attacked by the victorious Thebans, upon which Athens made peace with the Lacedæmonians. (M631) It would thus seem that the ancient Grecian States were perpetually jealous of any ascendant power, and their policy was not dissimilar from that which was inaugurated in modern Europe since the treaty of Westphalia—called the balance of power. Greece, thus far, was not ambitious to extend her rule over foreign nations, but sought an autonomous independence of the several States of which she was composed. Had Greece united under the leadership of Sparta or Athens, her foreign conquests might have been considerable, and her power, centralized and formidable, might have been a match even for the Romans. But in the anxiety of each State to secure its independence, there were perpetual and unworthy jealousies of each rising State, when it had reached a certain point of prosperity and glory. Hence the various States united under Sparta, in the Peloponnesian war, to subvert the ascendency of Athens. And when Sparta became the dominant power of Greece, Athens unites with Thebes to break her domination. And now Athens becomes jealous of Thebes, and makes peace with Sparta, in the same way that England in the eighteenth century united with Holland and other States, to prevent the aggrandizement of France, as different powers of Europe had previously united to prevent the ascendency of Austria.
