The Lesser Greek States
The second power of Greece, the Achaean league, adhered no less decidedly than the first to the alliance with Rome. Of the smaller powers, the Thessalians and the Athenians held by Rome; among the latter an Achaean garrison introduced by Flamininus into the citadel brought the patriotic party, which was pretty strong, to reason. The Epirots exerted themselves to keep on good terms, if possible, with both parties.
Thus, in addition to the Aetolians and the Magnetes who were joined by a portion of the neighbouring Perrhaebians, Antiochus was supported only by Amynander, the weak king of the Athamanes, who allowed himself to be dazzled by foolish designs on the Macedonian crown; by the Boeotians, among whom the party opposed to Rome was still at the helm; and in the Peloponnesus by the Eleans and Messenians, who were in the habit of taking part with the Aetolians against the Achaeans. This was indeed a hopeful beginning; and the title of commander-in-chief with absolute power, which the Aetolians decreed to the great-king, seemed insult added to injury.
There had been, just as usual, deception on both sides. Instead of the countless hordes of Asia, the king brought up a force scarcely half as strong as an ordinary consular army; and instead of the open arms with which all the Greeks were to welcome their deliverer from the Roman yoke, one or two bands of klephts and some dissolute civic communities offered to the king brotherhood in arms.
