Aeto'lia, an ancient division of Greece, situated on the north side of the Gulf of Corinth. Aetolia was originally settled by colonists from Epirus. By their exclusiveness these people estranged the other Greeks, so that even in the Golden Age they remained rude mountaineers and farmers. During the Macedonian wars the Aetolians became famous as soldiers of fortune and brought home great wealth. When the Gauls invaded Greece, the Aetolians took an active part in saving the country from the barbarians. Aetolia with Acarnania now forms a province of the kingdom of modern Greece.
