Mohammad Shah Qajar
In 1818 he commanded the attack on the Castle of Shirvan and his imperial father entitled him Hessam os-Saltaneh (lit. "Saber of the Monarchy"). After his eldest brother Mohammad Ali Mirza, the governor-general of Kermanshah, died from cholera in 1823 Mohammad Taqi Mirza was made 1826-1829 governor of that province. 1831-1834 he was made governor of Boroujerd. At his father's death in 1834 he was with some brothers imprisoned in the Ardabil citadel by the prime minister to avoid any attempts against the succession of the princes' nephew Mohammad Shah Qajar. He was released in 1848 by the next Qajar ruler Nasir al-Din Shah. Mohammad Taqi Mirza was also a poet under the pen name "Shokat".
