Parwāna or pervāne (Persian: پروانه, 'butterfly') was a court title of the Seljuk Sultanate of Rum (1077–1308).
It denoted the messenger who conveyed the sultan's personal messages.
[2] In the reign of Kilij Arslan II (1156–1192), a Danishmendid prince named Ẓāhir al-Dīn Ili held the office of parwāna.
He may have founded the caravanserai Alayhan [de], originally called Pervane.
[1] The powerful Muʿin al-Dīn Sulaymān held the office from 1256 and is known to posterity as Parwāna.
