Ardshír's accession is well received by the people. He makes Pírúz, son of Khusrau, the captain of the host. Guráz, on the pretext of avenging Khusrau Parwíz, but really with the intention of seizing the kingship for himself, schemes to bring about the death of the Sháh who is murdered at a banquet by Pírúz.
Ardshír (Artaxerxes III., September, A.D. 628—April, A.D. 630) was, according to Tabarí, only seven years old at his accession. By some accounts he was only one year old at the time.*
He was of course a mere puppet in the hands of the nobles. The “True Cross,” if the date of its elevation at Jerusalem—Sept. 14th, A.D. 629—be correct, must have been restored during his reign.*
§ 1. The Arabic Tabarí says that the realm was administered by Mih-Ázar-Gushnasp (Mihr 'Hasis in the Persian version), the High Steward, who had charge of the Sháh's person. This may account for his being made out to be a regicide in the Sháhnáma. He really seems to have been a well-intentioned man who did his best in very difficult circumstances. At all events, according to the Persian Tabarí, Shahrbaráz, after taking possession of Ctesiphon, slew him and other nobles on the pretext of avenging the death of Khusrau Parwíz.
§ 2. It appears that Shahrbaráz (Guráz) was not consulted when Ardshir was raised to the throne, and he made this an excuse for taking violent measures. The occasion was a favourable one for an ambitious general in command of an army. Moreover, he had an understanding, confirmed by matrimonial alliances, with Heraclius, who no doubt promised to recognise him if he became Sháh. He accordingly marched upon Ctesiphon with 6,000 or, according to another account, 60,000 troops. The High Steward made an attempt at resistance, but Shahrbaráz with the connivance of the captain of the guard and other chiefs was successful and the usual scenes of outrage and massacre ensued.*
