Eurydice I of Macedon

Eurydice (Greek: Εὐρυδίκη – from ευρύς eurys, "wide" and δίκη dike, "right, custom, usage, law; justice", literally "wide justice") was an Ancient Macedonian queen and wife of king Amyntas III of Macedon.

She was the daughter of Sirras and through her mother, Irra, she was the grand-daughter of the Lynkestian king Arrhabaeus, member of the Doric Greek Bacchiadae family. Eurydice had four children: Alexander II, Perdiccas III, Philip II, all of whom would be crowned kings, a daughter Eurynoe, and through her son Philip, she was the paternal grandmother of Alexander the Great. Literary, inscriptional and archaeological evidence indicates that she played an important public role in Macedonian life and acted aggressively in the political arena.

Eurydice's political activities mark a turning point in Macedonian history. She is the first known royal woman who actively took political action and successfully exerted political influence.
