Free city (classical antiquity)
A free city (Latin: civitas libera, urbs liberae condicionis; Greek: ἐλευθέρα καὶ αὐτόνομος πόλις) was a self-governed city during the Hellenistic and Roman Imperial eras. The status was given by the king or emperor, who nevertheless supervised the city's affairs through his epistates or curator (Greek: epimeletes) respectively.
