The first step in an attempt to resuscitate the league was taken in the 124th Olympiad (B.C. 284-280). Macedonia was at the time weakened by the troubles of a disputed succession: Pyrrhus was absorbed in his futile Italian expedition: a change in the sovereign of Egypt opened a way to a possible change of policy at Alexandria: and the death of Lysimachus gave the monarchs something else to do than to trouble themselves about the Peloponnese. At this period four of the Achaean towns, Dyme, Patrae, Tritaea, and Pharae, formed a league for mutual help. This proving, after a trial of five years, to have some stability, it was joined by Aegium, from which the Macedonian garrison was expelled. At intervals, of which we are not informed, this was again joined by Bura and Caryneia. These seven cities continued to constitute the entire league for twenty-five years; the federal magistrates consisting of two Strategi, elected by each city in turns, and a secretary. As to the doings of the league during this period we are entirely in the dark. The next step that we hear of is the abolition of the dual presidency and the election of Margos of Caryneia as sole Strategus. We are not told the reasons of the change; but it is clear that a divided command might often give room for delay, when delay was fatal; and for the conflict of local interests, where the interests of the community should be the paramount consideration. At any rate the change was made: and Margos, who had been a loyal servant of the league, was the first sole Strategus. His immediate successors we do not know. The next fact in the history of the league was the adherence of Sicyon, a powerful town and the first of any, not in the number of the old Achaean federation, to join. This therefore was a great step in the direction of extending the federation over the Peloponnese; and it was the work of the man destined to do much in moulding the league into the shape in which it attained its greatest effectiveness, Aratus of Sicyon. He found it weak; its cities poor and insignificant; with no aid from rich soil or good harbourage to increase its wealth or property;[117] he left it, not indeed free from serious dangers and difficulties,—in part the result of his own policy in calling in the aid of the Macedonians, in part created by the persistent hostility of Aetolia and Sparta,—but yet possessed of great vitality, and fast becoming the most powerful and influential of all the Greek governments; although at no time can it be spoken of as Panhellenic without very considerable exaggeration. Aratus had been brought up in exile at Argos, after the murder of his father Cleinias (B.C. 271); and, when twenty years of age, by a gallant and romantic adventure, had driven out the tyrant Nicocles from Sicyon (B.C. 251). He became the chief magistrate of his native town, which he induced to join the Achaean league, thus causing, as I have said, the league to
