安提柯三世
The king of Macedonia, Antigonus III Doson was keen to restore Macedonian influence in the Peloponnese for the first time in almost two decades. In 224 BC, he signed an alliance with the Achaeans, Boeotians, Thessalians and the Acarnanians. With his rear secured by treaties, Antigonus invaded the Peloponnese and drove the Spartans out of Argos, taking Orchomenus and Mantineia in the process.
