Antigonid Empire

The Antigonid Empire (Greek: Αντιγονική Αυτοκρατορία; Antigonikí Aftokratoría) is a Hellenistic state that ruled Macedon, Greece, Epirus, Illyria, parts of Southern and Eastern Italy and parts of Sicily. The Empire is ruled by its eponymous dynasty, which was named after its patriarch Antigonus I Monophthalmus.

The Antigonids ousted the Antipatrid dynasty from Pella, and consolidated their power in the Macedonian capital. Facing the threat of Thracian invasion from the north, Perseus II Euergetes launched a punitive expedition to vassalize the Odrysian Kingdom. Years later, under the reign of Bathycles II Callinicus, they expanded eastward, defeating the Epirots in the Apollonian War and expanded further north to southern Illyria.
