Cleomenean War
Cleomenes III ascended the throne of Sparta in 236 BC or 235 BC, after deposing his father, Leonidas II. His accession ended a decade-long period of heightened conflict between the two royal families. The war was fought by Sparta and its ally, Elis, against the Aetolian League and Macedon. It ended in a Macedonian and Achaean victory.
