Izadgushasp

Izadgushasp, known in Byzantine sources as Isdigousnas, was a Sasanian nobleman from the House of Mihran. He served as one of Khosrau's Viziers.

Biography
Izadgushasp is first mentioned during the reign of Khosrau I, as one the highest dignitaries and most powerful noblemen. He had a brother named Phabrizus (Fariburz) who also held high offices. Procopius describes them as: "both holding most important offices ... and at the same time reckoned to be the basest of all Persians, having a great reputation for their cleverness and evil ways." During the Lazic War, Izadgushasp and Phabrizus played an important role in the capture of Lazica. During the peace negotiations to end the war, Izadgushasp was the spokesman of the Sasanians, and made a treaty with the Byzantines in which they paid a great tribute of gold.

In 573, during the Byzantine–Sasanian War of 572–591, Khosrau I sent an army under Adarmahan to invade Syria, while he himself along Izadgushasp and Phabrizus led an army towards Dara, where they captured the city after 4 months, while Adarmahan sacked several cities in Syria, which included Apamea. Justin reportedly lost his mind after these Byzantine disasters, and abdicated. In 579, Khosrau was succeeded by his son Hormizd IV, who later ordered the death of 13,600 nobles and religious members, which included Izadgushasp.
