Fada'iyan-e Islam

Its first assassination was of a nationalist, anti-clerical author named Ahmad Kasravi, who was stabbed and killed in 1946. Kasravi is said to have been the target of Ayatollah Khomeini's demand in his first book, Kashf al Asrar (Key to the Secrets), that "all those who criticized Islam" are mahdur ad-damm, (meaning that their blood must be shed by the faithful).[9] Secularist Iranian author Amir Taheri argues that Khomeini was closely associated with Navvab Safavi and his ideas, and that Khomeini's assertion "amounted to a virtual death sentence on Kasravi."[12]

Hussein Emami, the assassin and a founding member of the Fada'iyan, was promptly arrested and sentenced to death for the crime. The Iranian intelligentsia united in calling for an example to be made of him. Emami, however, was spared the gallows. According to Taheri, he roused religious defenders and used his prestige as a seyyed, or descendant of the Islamic prophet Muhammad, to demand he be tried by a religious court. Khomeini and many of the Shia clergy pressured the Shah to give Emami a pardon, taking advantage of the Shah's political difficulties at that time, such as the occupation of Azerbaijan province by Soviet troops. Khomeini himself asked the Shah for the pardon.[13]

In 1949, the group killed court minister (and former prime minister) Abdolhossein Hazhir. On 7 March 1951, the Prime Minister Haj Ali Razmara was assassinated, in retaliation for his advice against nationalizing the oil industry.[8][14] Three weeks later the Education and Culture Minister Ahmad Zangeneh was assassinated by the group. Razmara's assassination was said to have moved Iran "further away from a spirit of compromise and moderation in relation to the oil problem" and "so frightened the ruling classes that concession after concession was made to nationalist demands in an attempt to pacify the intensely aroused public indignation."[15] An assassination attempt on Shah Mohammad Reza Pahlavi, on 4 February 1949, was carried out by Fakhr-Arai; Fakhr-Arai was first attributed to be a member of the communist Tudeh Party of Iran,[16] but he was later found to more likely be a religious fundamentalist member of Fada'iyan-e Islam.[17][18]

In addition to Emami, Khalil Tahmasebi, the assassin of Razmara, was also pardoned by the Iranian Parliament during the premiership of Mohammad Mossadegh.[19] Ayatollah Abol-Ghasem Kashani, a powerful member of parliament and a supporter of the Fadayan, "arranged for a special Act to be passed quashing the death sentence on Tahamsebi and declaring him (Tahamsebi) to be a soldier of Islam,"[20] to the further consternation of Iranian secularists. However, following the fall of Mossaddegh Tahmasebi was arrested again and tried in 1952.[19] He was sentenced to death and executed in 1955.[19] In addition, Ayatollah Kashani ended his alliance with Mossadegh and become close to the Shah after the assassination.[8][19]

Although the Fada'iyan strongly supported the nationalization of Iran's foreign-owned oil industry, they turned against the leader of the nationalization movement, Mohammad Mossadeq, when he became prime minister, because of his refusal to implement sharia law and appoint strict Islamists to high positions.[21] The danger from the Fada'iyan "was one of the primary factors accounting for Mosaddeq's decision to move the prime minister's office to his own residence."[22] Another assassination attempt on 15 February 1952 badly wounded Hossein Fatemi, "Mosaddeq's dynamic and capable aide" and foreign minister. That left Fatemi "badly wounded and effectively disabled for almost eight months." The attempted assassination was planned by the group's second in command, Abolhossein Vahedi, and carried out by a teenage member of the group.[22]

In 1955, Navvab Safavi and "other members of the Fedayeen of Islam, including Emami," were finally executed.[23] The group continued however, turning, according to author Baqer Moin, to Ayatollah Khomeini as a new spiritual leader,[24] and reportedly being "reconstructed" by Khomeini disciple, and later controversial "hanging judge," Sadegh Khalkhali.[25] It is thought to have carried out the assassination of Iranian Prime Minister Hassan Ali Mansour in 1965. Mansour is reported to have been "tried" by a secret Islamic court, made up of Khomeini followers Morteza Motahhari and Ayatollah Mohammad Beheshti, and sentenced to death "on a charge of 'warring on Allah' as symbolized by the decision" to send Khomeini into exile. The three men who carried out the "sentence" - Mohammad Bokara'i, Morteza Niknezhad and Reza Saffar-Harandi - "were arrested and charged as accomplices", but the story of both the trial and the sentence was not revealed until after the revolution.[26]

During the 1979 Iranian Revolution, some of the Fada'iyan's objectives were practiced by Islamic Republic of Iran, though in a modified way. Meaning there are similarities between Islamic Republic of Iran and Fada'iyan's views on issues like Islamic justice, the right of minorities and women, the place of poor, the cleric's position in the Islamic society, attitude toward foreign powers, etc. Fada'iyan's mentality in these issues is best served by some organizations in new Iran, such as Foundation of the Impoverished (Bonyād-e mostażʿafān),Revolutionary Guard (Sepāh-e pāsdārān-e enqelāb-e Eslāmī),the chair of the Discretionary Council (Šūrā-ye maṣleḥat-e neẓām), etc.[27]
