Favored by his father since he was a little boy, he was appointed vice-governor of Azerbaijan in 1831 when Abbas Mirza traveled to put down an uprising in Khorasan.
The residence of the governor was besieged by the rebels, and because a solution was unattainable, Mohammad Shah had in 1840 Fereydun Mirza dismissed from his office and sent back to the capital of Tehran.
Order was thus brought back to Khorasan, and Fereydun Mirza was rewarded with lavish presents by Naser al-Din Shah for this victory.
[1] Regarded as one of the more virtuous and intelligent Qajar princes, Fereydun Mirza is said to have shown "benevolence to the entire population of Fars."
He wrote poetry under the pen name "Farrokh"; some of his works are included in the Majma al-fosaha by Reza-Qoli Khan Hedayat and Hadiqat al-sho'ara by Ahmad Divanbeygi.
