History of the Peloponnesian War

When those of the Argives who heard their proposals had reported them to the government and the people, the Argives passed the decree, and chose twelve men, with whom any one of the Greeks who wished should conclude an alliance, except the Athenians and Lacedaemonians, neither of whom should have liberty to enter into treaty without the consent of the Argive people.

The Argives acceded the more readily to these proposals, because they saw that they should have the war with the Lacedaemonians, (for their treaty with them was on the point of expiring,) and also because they hoped to gain the supremacy of the Peloponnese. For at that time Lacedaemon was in very bad repute, and was despised in consequence of its misfortunes; while the Argives were in an excellent condition in all respects, as they had taken no part in the war against Athens, but had rather reaped the good fruits of having been in treaty with both sides.

Thus, then, the Argives were admitting into alliance such of the Greeks as wished it.

The Mantineans and their allies were the first to join them, through fear of the Lacedaemonians. For a certain part of Arcadia had been reduced to subjection by the Mantineans, while the war with the Athenians was still going on; and they thought that the Lacedaemonians would not allow their sovereignty over it, since they had now [*]( The force of the καί before σχολήν appears to be, leisure, as well as inclination. ) leisure to interfere; so that they gladly turned to the Argives, considering them to be a powerful state, and one which was always at variance with the Lacedaemonians, and under a democratical government like themselves.

When the Mantineans had revolted, the rest of the Peloponnese also was thrown into commotion, with the idea that they too ought to do the same; as they thought that they had changed sides through knowing more than the rest. At the same time they were angry with the Lacedaemonians, both on other grounds, and because it had been mentioned in the treaty with Athens, that it should be consistent with their oaths to add to it, or take from it, whatever might seem fit to both states, the Lacedaemonians and Athenians.

For it was this clause, above all, that caused the excitement in the Peloponnese, and set them on suspecting that the Lacedaemonians, in concert with the Athenians, might wish to reduce them to slavery: for it was only just, they thought, that the alteration should have been referred to all the allies.
