Hetaireia
The Hetaireia (Ancient Greek: Ἑταιρεία, romanized: Hetaireía, Byzantine Greek pronunciation: [(h)e.teˈri.a], Latinized as hetaeria) was a term for a corps of bodyguards during the Byzantine Empire. == Etymology and usage of the term == Hetaireia means 'Company, Association, Brotherhood' (from Ancient Greek: ἑταῖροι, romanized: hetaîroi, lit. 'companions, partners, comrades'), echoing the ancient Macedonian Companions and the Classical Greek aristocrats who attended symposia.
