Vakil ol-Ra'aya

Vakil ol-Ra'aya is a popular title best known for being adopted by the Zand ruler Karim Khan Zand at Shiraz in 1765.
The concept of the Vakil ol-Ra'aya may have been derived from the driyōšān-jādaggōv ud dādvar office of the pre-Islamic Sasanian Empire. The title first appears in two administrative documents written in Safavid Iran, being part of the office of the kalantar of Isfahan, the capital of the country. After that, the Vakil ol-Ra'aya became an autonomous office in its own right, being used in many provincial centers of Iran until the collapse of Qajar Iran.
