Reliable and valid information on the ministry is often difficult to obtain. Initially, the organization was known as SAVAMA, and intended to replace SAVAK, Iran's intelligence agency during the rule of the Shah, but it is unclear how much continuity there is between the two organizations—while their role is similar, their underlying ideology is radically different. It is suspected that the new government was initially eager to purge SAVAK elements from the new organization, but that pragmatism eventually prevailed, with many experienced SAVAK personnel being retained in their roles. Former SAVAK staff are believed to have been important in the ministry's infiltration of left-wing dissident groups and of the Iraqi Ba'ath Party. The formation of the ministry was proposed by Saeed Hajjarian to the government of Mir-Hossein Mousavi and then the parliament. There were debates about which branch of the state should oversee the new institution, and the other options apart from the presidency were the Judiciary system, the Supreme Leader, and Islamic Revolutionary Guard Corps. Finally, the government got the approval of Ayatollah Khomeini to make it a ministry, but a restriction was added to the requirements of the minister: that he must be a doctor of Islam. The ministry was finally founded on 18 August 1984, either abandoning, silently subsuming, or relegating to hidden existence many small intelligence agencies that had been formed in different governmental organizations. The five ministers since the founding of the ministry, have been Mohammad Reyshahri, Ali Fallahian, Ghorbanali Dorri-Najafabadi, Ali Younessi, Gholam Hossein Mohseni-Ejehei and Heyder Moslehi.
"Chain" assassinations
In late 1998, three dissident writers, a political leader and his wife were killed in Iran in the span of two months. After great public outcry and journalistic investigation in Iran and publicity internationally, prosecutors announced in mid-1999 that one Saeed Emami had led "rogue elements" in Iran's intelligence ministry in the killings, but that Emami was now dead, having committed suicide in prison. In a trial that was "dismissed as a sham by the victims' families and international human rights organisations", three intelligence ministry agents were sentenced in 2001 to death and twelve others to prison terms for murdering two of the victims. Two years later, the Iranian Supreme Court reduced two of the death sentencesto life. In 1999, critics of the Iranian government accused "rogue elements" of the ministry for the Chain murders of dissident writers and intellectuals, including assassination of Iranian political dissidents inside and outside the country.
