Gushnaspdad

Gushnaspdād, known in Byzantine sources as Gousanastadēs (Γουσαναστάδης), was a Sasanian nobleman, who was kanarang during the reign of Balash (r. 484-488), and Kavadh I (r. 488–531).

Biography
Gushnaspdad first appears in 484, as one of the supporters of Balash. After Balash's accession, Gushnaspdad urged the Sasanian noblemen to execute Kavadh I, the brother of Balash. He is reportedly said to have told the Sasanian noblemen while holding a knife: "You see this knife, how extremely small it is; nevertheless it is able at present time to accomplish a deed which, be assured, my dear Persians, a little later two myriads of mail clad men could not bring to pass."

However, the Sasanian nobles declined the decision, and instead had Kavadh imprisoned, who later managed to escape, and took refugee in Central Asia. In 488, Kavadh returned to Persia with the aid of the Hephthalites, and was joined by other Sasanian nobles, which included the Karenid Sukhra, and Adergoudounbades, a relative of Gushnaspdad. Kavadh then captured Ctesiphon, ascended the Sasanian throne, and had Gushnaspdad executed, who was replaced by Adergoudounbades as kanarang.
