Firuz Nirvasita (AD 638-710), also known as Firuz the Exile, was a Persian prince of the Sassanid dynasty who refounded the Indo-Sassanid Empire in northern India. The only son of Emperor Yazdegerd III, he was born the heir to the Persian throne. However, when he was less than a year old, his father was captured in battle against the Arabs and the throne usurped by his cousin Shahryar. Firuz died in 710 from food poisoning and was succeeded by his son Narsieh.
