Farhād Khān Qarāmānlu (Persian: فرهادخان قرامانلو; died 1598), also known by his honorific title of Rokn al-Saltana (Arabic: رکنالسلطنه, "Pillar of the state"), was a Turkoman military officer from the Qaramanlu family, and was the last member of the Qizilbash to serve as commander-in-chief (sipah-salar) of the Safavid Empire.
In 1589/90, Farhad Khan was given the task of having the grand vizier Mirza Mohammad Munshi arrested and executed, which he successfully did.
[1][2] However, a rebellion shortly occurred in Bia Pish once again, which forced Farhad Khan to invade the province for the second time.
Some time later, Farhad Khan and the Safavid grand vizier Hatem Beg Ordubadi campaigned in Khuzestan and Kohgiluyeh.
In the same year, he was replaced by prominent military officer Allahverdi Khan as the governor of Fars, but was instead given the governorship of Bia Pas.
[5] According to the English traveler Robert Shirley, during the battle, Farhad Khan betrayed the Safavid army by informing the Uzbeks about how they should attack.
However, according to Don Juan, Jalal al-Din Monajjem Yazdi, and Jonabadi, Farhad Khan had fled during the battle, which resulted that Abbas had him executed due to his cowardice.
[1] According to Iskandar Beg Munshi, Farhad Khan fled from the battle after being wounded, but was later accused of fleeing due to his cowardice.
