When he ascended the throne he recalled Nursi, the wazir of his father—who had retired and become a devotee in a fire temple—to public life, appointed him prime minister, and governed his subjects with justice. The surrounding potentates continued to pay their annual tribute into the treasury as in the time of his father Behrâm, while he himself imitated by his equity the ways of his ancestors, and of Kaiomarth the Peshdâdian.
After several years had elapsed the King of Rûm ceased to pay his usual tribute, whereon the Shâh of Erân despatched his prime minister Nursi with a numerous army of brave men to that country. When the Governor of Rûm had become aware of their bravery, he paid whatever he owed, whereon Nursi returned after having successfully accomplished his mission.
Yazdejerd is said to have had two sons, the name of the senior being Firûz, and of the junior Hormuz; but as the latter was his favourite, he appointed Firûz to be governor of the territory of Nimrûz [which consisted of the provinces of Mehrân and Sejestân], and made Hormuz his heir-apparent, saying: ‘Although the personal appearance of Firûz is more imposing, and he is several years older than Hormuz, I prefer the latter on account of his intelligence, modesty, and worth.’ When eighteen years of the reign of Yazdejerd had elapsed, he was gathered to his fathers. He kept up a powerful and respected government, and was surnamed ‘the soldier’s friend.’
