First Assembly (1983–1991) The first elections for the Assembly of Experts of the Leadership were held in December 1982 and the Assembly first convened in 1983. 76 of the total of 83 members were elected in the first round, the rest in the second. The full list of members and election results is available on the Princeton Iran Data Portal. As a number of members died, by-elections for replacement candidates were held in April 1988. The Assembly was chaired throughout the term by
Ayatollah Ali Meshkini, who chaired the Assembly also in subsequent terms until 2007. In 1985, the Assembly chose Ayatollah
Montazeri as the successor to Supreme Leader Grand Ayatollah
Khomeini. But on 26 March 1989 Khomeini dismissed him in a letter: "[...]you are no longer eligible to succeed me as the legitimate leader of the state." Following Khomeini's death on 3 June 1989, the Assembly of Experts chose
Ali Khamenei to be his successor as Supreme Leader in what proved to be a smooth transition. Initially, a council of three members, Ali Meshkini,
Mousavi Ardabili and Ali Khamenei, were proposed for Leadership. After rejection of a Leadership Council by the assembly, and lack of votes for Grand Ayatollah
Mohammad-Reza Golpaygani, Khamenei became the Supreme Leader by two-thirds of the votes.
Second Assembly (1991–1999) The Second Assembly was also chaired by Ayatollah Ali Meshkini. The full list of members and election results is available on the Princeton Iran Data Portal.
Third Assembly (1999–2007) The 3rd assembly was again chaired by Ayatollah Ali Meshkini, deputied by
Ali Akbar Hashemi Rafsanjani, and Ayatollah
Ebrahim Amini. The scribes were former Minister of Intelligence
Ghorbanali Dorri-Najafabadi and
Ahmad Khatami. The full list of members and election results is available on the Princeton Iran Data Portal.
Fourth Assembly (2007–2016) The election for the fourth assembly took place on 15 December 2006 and the Assembly first convened on 19 February 2007. In July 2007, chairman Ayatollah Meshkini died, and
Ayatollah Rafsanjani was elected to succeed him. On 8 March 2011, Ayatollah Mohammad-Reza Mahdavi Kani replaced Ayatollah Rafsanjani as chairman. On 4 June 2014, Mahdavi Kani fell into a coma after suffering a heart attack and died on 21 October 2014. He was succeeded by
Mahmoud Hashemi Shahroudi as acting chairman. The term was intended to last for ten years, rather than the usual eight, due to the "election aggregation" plan of the government put in place to allow the government to run elections simultaneously for the Assembly of Experts and the Parliament, thereby economizing election administration costs.
