For the first twenty-five years of the league between the cities I have mentioned, a secretary and two strategi for the whole union were elected by each city in turn. But after this period they determined to appoint one strategus only, and put the entire management of the affairs of the union in his hands. The first to obtain this honour was Margos of Caryneia. In the fourth year after this man’s tenure of the office, Aratus of Sicyon caused his city to join the league, which, by his energy and courage, he had, when only twenty years of age, delivered from the yoke of its tyrant. In the eighth year again after this, Aratus, being elected strategus for the second time, laid a plot to seize the Acrocorinthus, then held by Antigonus; and by his success freed the inhabitants of the Peloponnese from a source of serious alarm: and having thus liberated Corinth he caused it to join the league. In his same term of office he got Megara into his hands, and caused it to join also. These events occurred in the year before the decisive defeat of the Carthaginians, in consequence of which they evacuated Sicily and consented for the first time to pay tribute to Rome. Having made this remarkable progress in his design in so short a time, Aratus continued thenceforth in the position of leader of the Achaean league, and in the consistent direction of his whole policy to one single end; which was to expel Macedonians from the Peloponnese, to depose the despots, and to establish in each state the common freedom which their ancestors had enjoyed before them. So long, therefore, as Antigonus Gonatas was alive, he maintained a continual opposition to his interference, as well as to the encroaching spirit of the Aetolians, and in both cases with signal skill and success; although their presumption and contempt for justice had risen to such a pitch, that they had actually made a formal compact with each other for the disruption of the Achaeans.
