After the death of Antigonus, however, the Achaeans made terms with the Aetolians, and joined them energetically in the war against Demetrius; and, in place of the feelings of estrangement and hostility, there gradually grew up a sentiment of brotherhood and affection between the two peoples. Upon the death of Demetrius, after a reign of only ten years, just about the time of the first invasion of Illyricum by the Romans, the Achaeans had a most excellent opportunity of establishing the policy which they had all along maintained. For the despots in the Peloponnese were in despair at the death of Demetrius. It was the loss to them of their chief supporter and paymaster. And now Aratus was for ever impressing upon them that they ought to abdicate, holding out rewards and honours for those of them who consented, and threatening those who refused with still greater vengeance from the Achaeans. There was therefore a general movement among them to voluntarily restore their several states to freedom and to join the league. I ought however to say that Ludiades of Megalopolis, in the lifetime of Demetrius, of his own deliberate choice, and foreseeing with great shrewdness and good sense what was going to happen, had abdicated his sovereignty and become a citizen of the national league. His example was followed by Aristomachus, tyrant of Argos, Xeno of Hermione, and Cleonymus of Phlius, who all likewise abdicated and joined the democratic league.
