Mohammad Montazeri (Persian: محمد منتظری; 1944–28 June 1981) was an Iranian cleric and military figure.
[1] He began opposition activities against Mohammad Reza Pahlavi after the June 1963 events that led to the exile of Khomeini.
[8][9] The group, namely People's Revolutionary Organization of the Islamic Republic of Iran, was founded by Montazeri and Ali Akbar Mohtashamipur with the aim of assisting liberation movements in Muslim countries.
[3][11] In addition, he fought with the Palestine Liberation Organization (PLO) and other Palestinian and Shiite armed groups in the country.
[12] Montazeri was one of the three Iranian key officials along with Mostafa Chamran and Mohtashamipur who strengthened Iran's commitment to Lebanon.
[6] In the mid-1970s Montazeri formed his base in Syria and continued his close relations with the PLO and the Libyan ruler Muammar Gaddafi’s secret service.
[20] In order to export Islamic revolution to other countries he and Mehdi Hashemi founded one of the earliest groups, the SATJA, in the spring of 1979.
[14][21] In December 1979 he organized a campaign to support and join the Palestinian militants, fighting in the Lebanese civil war.
[21] Montazeri headed a faction of the Guards in Tehran that functioned as a strong arm of the Supreme Leader Khomeini.
[9] The OLM put into practice the Iranian support for the Shi‘a movements in Iraq and the Gulf[22] as well as those in Saudi Arabia, Lebanon and Afghanistan.
"[25] Montazeri joined and led the Muslim People's Republic Party[26] and became a member of the first Majlis in March 1980.
[26] In addition, Montazeri served at the supreme defense council[29] and was the prayer leader in Tehran until his death.
[21] His father, Ayatollah Hossein Ali Montazeri, publicly reprimanded him and stated that Mohammad had poor mental health because he had been tortured by the former Shah's secret police.
