After the death of Kavad II, the Wuzurgan elected Ardashir as his successor, who was only a 7-year-old boy. In reality, however, he exercised little power and his empire was controlled by his vizier Mah-Adhur Gushnasp, whose duty was to protect the empire until Ardashir became old enough to rule. The Iranian historian al-Tabari says the following thing about Mah-Adhur Gushnasp's administration of the Empire; "Mah-Adhur Gushnasp carried on the administration of the kingdom in [such] an excellent fashion, [and with such] firm conduct, [that] no one would have been aware of Ardashir III's youthfulness."
