Jamal al-Din Khan was the son of the local Talysh leader Mir-Abbas Beg, who claimed to be a seyyed (descendant of the Islamic prophet Muhammad).
He rose to important posts in Nader Shah's army and was assigned the task of putting down Kalb Hoseyn Beg's uprising in southern Talish in 1744.
[4][5] Jamal al-Din preserved his fathers correspondence with Russia, sending a letter to its empress Catherine II (r. 1762–1796) that pledged his allegiance to her and offered the Russian troops access to his domains.
[6] After destroying Zohrab's army and seizing control of Uluf and Dashtvand, Jamal al-Din now directed his attention towards Astara.
The following year, Hedayat-Allah Khan launched an attack into Talish, where he defeated and captured Jamal al-Din, imprisoning him in Rasht.
