The immediate effect of the theatrical revolution at Thebes was the death of three of the leading generals concerned. Sparta in disgust executed two of the defeated harmosts with short shrift of trial. The Athenians put to death one of the generals who had gone to the relief of the Thebans, and outlawed the other. They were not yet ready to take a step in renewal of the ancient wars with Sparta. The Thebans felt themselves now quite left at the mercy of the Lacedæmonians, and, indeed, it was only a Spartan who could seemingly have been of aid to them. Sphodrias, a harmost of Thespiæ, was hot-headed enough to dream of taking Athens unawares and seizing the Piræus. He was so slow on the march, however, that daylight found him only at Eleusis. Thereupon, his surprise failing, he retreated, ravaging the country through which he passed. Athens had shown her purpose to keep the peace with Sparta by her punishment of the rash officers who had gone to the relief of Thebes, and yet here was a Spartan general marching against Athens and playing havoc in the vicinity. A prompt disavowal on the part of Sparta was demanded, with the execution of Sphodrias. Sphodrias did not dare return to Sparta for trial, feeling that his doom was certain. And so it would have been had it not been for the influence of Agesilaus who was notably a tender-hearted man and could not resist the pleadings of his son who was on terms of Grecian intimacy with the son of Sphodrias. Acquittal followed, and Athens could not but feel herself insulted and forced into an open declaration for Thebes. War broke out and was busy for six years. It took the form, as usual, of a war between two leagues.
Sparta felt called upon to deal gently with her remaining confederates after she saw Chios, Byzantium, Rhodes, and Mytilene revolt at once to Athens. Sparta divided her league into ten classes: herself the first, the Arcadian states second and third, Elis the fourth, the Achæans the fifth, Corinth and Megara the sixth, Sicyon, Phlius, and the towns of the Argolic Acte the seventh, the Acarnanians the eighth, the Phocians and Locrians the ninth, Olynthus and the other cities on the coast of Thrace the tenth.
To Athens it seemed as if destiny had forced her once more to the forefront of a league against Sparta, a league which should bring her back to her old-time mastery of the seas. This league, which is called by Busolt
“Meanwhile Athens had striven with zeal to erect again the twice-lost lordship of the seas. Immediately after the King’s Peace the alliance with Chios, Mytilene, Methymna, and Byzantium was renewed: Rhodes also entered into treaty with Athens, as her Asia Minor league had gone to pieces at the death of Glos, about 379. The effort to resume the old relations with the Chalcidians in Thrace had been quickly foiled by the Spartan intervention; but instead, as we have seen, Thebes had entered into alliance with Athens in the spring of 378. And now, after the breach with Sparta was definite, Athens lifted up to all Hellenes and barbarians, where they were not under Persian rule, the summons to band together in a league against the encroachment of Sparta. The provisions of the King’s Peace should fashion the ground plan. The autonomy of all the states party to it was guaranteed; the Persian king was to be recognised as lord of the continent of Asia: Athens renounced all claims on her old colonial possessions and for the future the acquisition of houses and lands anywhere in the confederacy should be forbidden to the Athenians. For the administration of affairs a congress (
