Phthia of Macedon
King of Epirus
Phthia (in Greek Φθια; lived 3rd century BC) was a daughter of Alexander II (272–260 BC), king of Epirus, who was married to Demetrius II (239–229 BC), king of Macedonia. The match was arranged by her mother Olympias, who was desirous of thus securing the powerful assistance of the Macedonian king to support herself on the throne of Epirus after the death of Alexander.
