Naser al-Din was assassinated by Mirza Reza Kermani, a follower of Jamāl al-Dīn al-Afghānī, when he was visiting and praying in the Shah Abdol-Azim Shrine on 1 May 1896. It is said that the revolver used to assassinate him was old and rusty, and had he worn a thicker overcoat, or been shot from a longer range, he would have survived the attempt on his life. Shortly before his death, he is reported to have said “I will rule you differently if I survive!” The assassin was prosecuted by the defence minister, Nazm ol-Dowleh.Nasser-al-Din Shah’s assassination and the subsequent execution of Mirza Reza Kermani marked a turning point in Iranian political thought that would ultimately lead to the Iranian Constitutional Revolution during his successor Mozzafar-al-Din Shah’s turbulent reign.[
