History of the Peloponnesian War

After the revolt of the Argives from the league, the Mantineans also, though they withstood it at first, yet being too weak without the Argives, made their peace with the Lacedaemonians and laid down their command over the other cities.

And the Lacedaemonians and Argives with a thousand men of either city having joined their arms, the Lacedaemonians first, with their single power, reduced the government of Sicyon to a smaller number; and then they both together dissolved the democracy at Argos. And the oligarchy was established conformable to the state of Lacedaemon. These things passed in the end of winter and near the spring. And so ended the fourteenth year of this war.
