Mirza Mohammad Khan Beglerbegi (Persian: میرزا محمد خان بیگلربیگی) was a 19th-century Iranian official from the Qajar tribe and the third of son of Asef al-Dowleh.
[1] The misconduct of Hamzeh Mirza's army in Mashhad and its surroundings in the fall of 1848 led to unrest, which significantly increased Hasan Khan Salar's opportunities.
The latter openly rebelled on 25 August 1848, when he had the motavalli-bashi (custodian) Hajji Mirza Abdollah Kho'i and darugha (prefect) Ebrahim Soltan killed.
After Hasan Khan Salar was informed of the situation in Mashhad, he marched towards the city with 2,000 Turkmen soldiers.
[3] Hasan Khan Salar continued enlarging his domain in Khorasan, but was ultimately defeated and executed in the spring of 1850 by the Qajar prince Morad Mirza.
