During this Hellenistic period, and after the creation of the four mini-empires, city-states were weakened and joined confederacies. Aetolian and Achaean emerged as the two strongest confederacies and sought to play a role in Greece’s later political structure. Later that century, these two confederacy powers would engage in a quasi-civil war (227-217 B.C.), with armies form both sides fighting each other. In addition, they actively participated in a turmoil that led to the Macedonian Wars, which bled out the 2nd century B.C. and found the Romans as the victors. With the Romans winning the Macedonian Wars, this marked the end of the Macedonian continuity and the beginning of the Roman Era in Greece.
