When Khosrow I ascended the Sasanian throne in 531, he began a series of reforms that was started by his father and predecessor Kavadh I. These reforms were mostly aimed at the elites of the Sasanian Empire, who had become too powerful and had been able to depose several Sasanian rulers. Khosrow was quite successful in these reforms, and after his death in 579, he was succeeded by his son Hormizd IV, who continued his father's policies, but in a harsher way; in order to control the elites, he, in the words of Shapur Shahbazi, "resorted to harshness, denigration, and execution."[1] Hormizd was extremely hostile to the elites and did not trust them; therefore, he constantly sided with the lower classes.
