Caste
Iran

Pre-Islamic Sassanid society was immensely complex, with separate systems of social organisation governing numerous different groups within the empire. Historians believe society comprised four social classes, which linguistic analysis indicates may have been referred to collectively as "pistras". The classes, from highest to lowest status, were priests (Asravan), warriors (Arteshtaran), secretaries (Dabiran), and commoners (Vastryoshan).
