Because Hellenistic kingship was personal and charismatic (see KINGSHIP, HELLENISTIC), the royal court was essentially the household of the royal family and is often referred to as oikos in Greek sources. Another common designation is aule, literally “court,” probably derived from the fact that the core of Hellenistic palaces was an open courtyard surrounded by banqueting rooms (see PALACES, HELLENISTIC). However, in ancient historiography and documentary evidence, the royal court is usually defined in social terms like “retinue” (therapeia), “courtiers” (hoi peri ten aulen or aulikoi), and notably “the friends of the king” (hoi philoi tou basileos).
