I have just started reading Women and Monarchy in Macedonia by Elizabeth Donnelly Carney. The following quotation has made a big impression on me. For context, the Eurydice being talked about here is the mother of Alexander II, Perdiccas III, and Philip II - Alexander’s father.
Eurydice’s political career marks a turning point in Macedonian history; she is the first royal woman we know of who took political action and successfully exerted political action and successfully exerted political influence.
Elizabeth Donnelly Carney Women and Monarchy in Macedonia p.40
Carney goes on to note how active royal women were in Macedon for the rest of the fourth century until, early in the third century, their influence waned after the Antigonids came to power.
