From there, Lucius, Attalus, the Rhodians, and the Athenians sent ambassadors to the Achaian League in order to bring them into the war on the Roman side. The league held an assembly at Sicyon to decide how to respond, which was extremely contentious. On the one hand, the Achaians were still at war with Sparta and they were allied to Macedonia, but on the other hand their new chief magistrate Aristaenus was pro-Roman and the Romans promised to give the city of Corinth to the League. The representatives of Argos, Megalopolis, and Dyme, which all had particularly strong ties with Philip, left the meeting. The rest of the assembly voted to join the anti-Macedonian alliance.
