Name

Officially, the empire was known as the Kingdom of the Iranians (Middle Persian: ērānšahr, Parthian: aryānšahr, Greek: Arianōn ethnos); the term is first attested in the trilingual Great Inscription of Shapur I, where the king says "I am the lord of the Realm of the Iranians".

More commonly, as the ruling dynasty was named after Sasan, the empire is known as the Sasanian Empire in historical and academic sources. This term is also recorded in English as the Sassanian Empire, the Sasanid Empire, and the Sassanid Empire. Historians have referred to the Sasanian Empire as the Neo-Persian Empire, since it was the second Iranian empire that rose from Pars (Persis), while the Achaemenid Empire was the first.
