In 1908, Mohammad Ali Shah Qajar bombardment of the Majlis. Tabriz was blockaded. At that time, Haji Mirza Hassan Mojtahed and a group of like-minded people in Dohchi formed the Islamic Association, and Kasravi, who was still a student at the time, was watching. After that, Tabriz suffered from conflict and bloodshed for four months, which resulted in the cessation of the Islamic Association. Kasravi, who was seventeen at the time, was forced to stay at home and read books.
On 11 March 1946, while being tried on charges of “slander against Islam,” Kasravi and one of his assistants named Seyyed Mohammad Taghi Haddadpour, were knifed and killed in open court in capital by followers of Navvab Safavi, a Shi’a extremist cleric who had founded an organization called the Fadayan-e Islam (literally Devotees of Islam), led by two brothers, Hossein and Ali-Mohammad Emami. The same group had failed in assassinating Kasravi earlier in April 1945 in capital. Ayatollah Borujerdi and Ayatollah Sadr al-Din al-Sadr had issued fatwas for killing Ahmad Kasravi.
