 Yazdegerd II, however, was still fully aware of the longstanding conflict between the crown and the nobility and priesthood, which had culminated in the murder of several Sasanian monarchs.Yazdegerd II's primary goal throughout his reign was thus to combat the internal and external issues posing a danger to country by strengthening the royal centralisation of the bureaucracy, which demanded the cooperation of the aristocracy.The justification behind this is later apparent when Yazdegerd II appointed Adhur-Hormizd as the new governor ("marzban") of Armenia in 451, putting an end to the persecution of non-Zoroastrians in Armenia and allowing religious freedom in the country.
