Summary This article aims to examine the turbulent course of the Aetolian League in the confused years after the Antiochian War up until 160/159, when its leader at the time, Lykiskos, passed away. Military defeats, political developments and economic problems will be studied together in order to form an accurate interpretation of the internal strife inside the Koinon. In addition, the factor of Rome also needs to be taken into consideration, as the new power seems to have adopted a cautious (...) stance, intervening in the League’s internal politics only when it was considered necessary. Prominent Aetolians of this era, like Thoas and Lykiskos, as well as their crucial political roles, are also analysed. (shrink)
