Hasan Khan Salar (Persian: حسن خان سالار, died 1850) was a Qajar prince most notable for his rebellion and support for Bahman Mirza Qajar's claim on the Iranian throne.
He was the fifth son of the Qajar chief minister Allahyar Khan Asef ad-Dowleh and the oldest son of Maryam Khanom, the fifth daughter of Fath-Ali Shah Qajar, and therefore, was a cousin of the incumbent Shah of his time, Mohammad Shah Qajar.
Hasan Khan Salar rose to power after his father Allahyar Khan Asef ad-Dowleh, former governor of the Khorasan province, was exiled for rebellion.
His revolt was eventually defeated during the prime ministry of Amir Kabir.
[2][3][4] Salar, his son Amir Aslan Khan, and his brother were executed afterwards in an unusually harsh punishment that demonstrated Amir Kabir's determination to exert control over the region.
