After his father's death in 1834, he supported his brother Hossein Ali Mirza in a failed attempt to seize the throne, which led to his capture, blinding, and imprisonment.

[3] Following the signing of the notorious Treaty of Turkmenchay in 1828, Hasan Ali Mirza requested his father Fath-Ali Shah to grant him the title of "Nayeb ol-Saltaneh", traditionally held by the crown prince, and expressed his willingness to command the Iranian army and continue the conflict with Russia.

Wealthy and powerful, Hossein Ali Mirza viewed himself as the legitimate heir to Fath-Ali Shah's throne and frequently defied the central authority.

Forces loyal to Mohammad Shah soon defeated Hossein Ali Mirza's supporters, and the rebellious prince was captured and taken to Tehran.

Additionally, Hasan Ali Mirza was a poet, composing verses in Persian under the pen name Shekaste ("broken") and he continued writing poetry until his death in 1854.
