Ligue achéenne
As both sides were then trying to find new allies, the Achaean League turned again to Macedon. But the new Macedonian king, Philip V, was not keen on war with the Aetolians. Ultimately, the Achaeans did convince Philip, and Boeotia, Acarnania, and Epirus also joined the alliance. The Aetolians allied with Sparta and Elis, and in 219 BC again invaded Achaean League territory. This invasion attempt was put down near Aegeira, but it was not a decisive defeat.
