The Supreme Leader of Iran (Persian: , romanized: rahbar-e mo'azzam-e irn (listen)), also referred to as Supreme Leader of the Islamic Revolution ( , rahbar-e mo'azzam-e enqelb-e eslmi), but officially called the Supreme Leadership Authority ( , maqm mo'azzam rahbari), is the head of state and the highest political and religious authority of the Islamic Republic of Iran. The armed forces, judiciary, state television, and other key government organisations such as Guardian Council and Expediency Discernment Council are subject to the Supreme Leader. The current lifetime officeholder, Ali Khamenei, has issued decrees and made the final decisions on the economy, the environment, foreign policy, education, national planning, and other aspects of governance in Iran. Khamenei also makes the final decisions on the amount of transparency in elections, and has dismissed and reinstated presidential cabinet appointees.The Supreme Leader directly chooses the ministers of Defense, Interior, Intelligence and Foreign Affairs, as well as certain other ministers, such as the Education, Culture and Science Minister. Iran's regional policy is directly controlled by the office of the Supreme Leader with the Ministry of Foreign Affairs' task limited to protocol and ceremonial occasions. All of Iran's ambassadors to Arab countries, for example, are chosen by the Quds Force, which directly reports to the Supreme Leader.The office was established by the Constitution of Iran in 1979, pursuant to the concept of the Guardianship of the Islamic Jurist. According to the Constitution, the powers of government in the Islamic Republic of Iran are vested in the legislature, the judiciary, and the executive powers, functioning under the supervision of the Supreme Leader. The style "Supreme Leader" (Persian: , romanized: rahbar-e mo'azzam) is commonly used as a sign of respect although the Constitution simply designates them as "Leader" (, rahbar).

The Supreme Leader ranks above the President of Iran and personally appoints the heads of the military, the government, and the judiciary. Originally the constitution required the Supreme Leader to be Marja'-e taqlid, the highest-ranking cleric in the religious laws of Usuli Twelver Shia Islam. In 1989, however, the constitution was amended and simply asked for Islamic "scholarship", thus the Supreme Leader could be a lower-ranking cleric.In its history, the Islamic Republic of Iran only has had two Supreme Leaders: Ruhollah Khomeini, who held the position from 1979 until his death in 1989 and Ali Khamenei, who has held the position since Khomeini's death.

In theory, the Supreme Leader is elected by the Assembly of Experts. However, all candidates for membership at the Assembly of Experts (including the President and the Majlis (parliament)) must have their candidacy approved by the Guardian Council, whose members in turn, are half appointed unilaterally by the Supreme Leader and half subject to confirmation by the Majlis after being appointed by the head of the Iranian judiciary, who is himself appointed by the Supreme Leader. Thereby, the Assembly has never questioned the Supreme Leader. There have been cases where incumbent Ali Khamenei publicly criticized members of the Assembly, resulting in their arrest and subsequent removal. There also have been cases where the Guardian Council repealed its ban on particular people after being directed to do so by Khamenei. The Supreme Leader is legally considered "inviolable", with Iranians being routinely punished for questioning or insulting him.



Sayyid Ruhollah Musavi Khomeini (UK: khom-AY-nee, US: khohm-; Persian: سید روح‌الله موسوی خمینی [ɾuːholˈlɒːhe xomejˈniː] (listen); 17 May 1900 – 3 June 1989), also known as Ayatollah Khomeini, was an Iranian political and religious leader who served as the 1st Supreme Leader of Iran from 1979 until his death in 1989. He was the founder of the Islamic Republic of Iran and the leader of the 1979 Iranian Revolution, which saw the overthrow of the last Shah of Iran, Mohammad Reza Pahlavi, and the end of the Persian monarchy. Following the revolution, Khomeini became the country's first supreme leader, a position created in the constitution of the Islamic Republic as the highest-ranking political and religious authority of the nation, which he held until his death. Most of his period in power was taken up by the Iran–Iraq War of 1980–1988. He was succeeded by Ali Khamenei on 4 June 1989.

Khomeini was born in Khomeyn, in what is now Iran's Markazi Province. His father was murdered in 1903 when Khomeini was two years old. He began studying the Quran and Arabic from a young age and was assisted in his religious studies by his relatives, including his mother's cousin and older brother.

Khomeini was a marja ("source of emulation") in Twelver Shia Islam, a Mujtahid or faqih (an expert in Sharia) and author of more than 40 books, but he is primarily known for his political activities. He spent more than 15 years in exile for his opposition to the last shah. In his writings and preachings he expanded the theory of welayat-el faqih, the "Guardianship of the Islamic Jurist (clerical authority)", to include theocratic political rule by Islamic jurists. This principle (though not known to the wider public before the revolution), was appended to the new Iranian constitution after being put to a referendum. According to The New York Times, Khomeini called democracy the equivalent of prostitution. Whether Khomeini's ideas are compatible with democracy and whether he intended the Islamic Republic to be democratic is disputed. He was Time magazine's Man of the Year in 1979 for his international influence, and Khomeini has been described as the "virtual face of Shia Islam in Western popular culture". In 1982, he survived one military coup attempt. Khomeini was known for his support of the hostage takers during the Iran hostage crisis, his fatwa calling for the murder of British Indian novelist Salman Rushdie, and for referring to the United States as the "Great Satan" and Soviet Union as the "Lesser Satan." Khomeini has been criticized for these acts and for human rights violations of Iranians (including his ordering of execution of thousands of political prisoners, war criminals and prisoners of the Iran–Iraq War).He has also been lauded as a "charismatic leader of immense popularity", a "champion of Islamic revival" by Shia scholars, who attempted to establish good relations between Sunnis and Shias, and a major innovator in political theory and religious-oriented populist political strategy. Khomeini held the title of Grand Ayatollah and is officially known as Imam Khomeini inside Iran and by his supporters internationally. He is generally referred to as Ayatollah Khomeini by others. In Iran, his gold-domed tomb in Tehran's Behesht-e Zahrāʾ cemetery has become a shrine for his adherents, and he is legally considered "inviolable", with Iranians regularly punished for insulting him. A cult of personality developed around Khomeini after the Iranian Revolution.
