Grand Ayatollah Sayyed Ruhollah Mousavi Khomeini (24 September 1902 – 3 June 1989) was an Iranian religious leader and politician, and leader of the 1979 Iranian Revolution which saw the overthrow of Mohammad Reza Pahlavi, the Shah of Iran. Following the revolution and a national referendum, Khomeini became the country's Supreme Leader — a position created in the constitution as the highest ranking political and religious authority of the nation — until his death.

Khomeini was a marja or marja al-taqlid ("source of emulation", also known as a Grand Ayatollah) in Twelver Shi'a Islam, but is most famous for his political role. In his writings and preachings he expanded the Shi'a Usuli theory of velayat-e faqih, the "guardianship of the jurisconsult (clerical authority)" to include theocratic political rule by Islamic jurists. Beloved by millions of Iranians he was "the Imam, an ascetic spiritual leader whose teachings are unquestioned." Both his return from exile and his funeral were occasions of great emotional outpouring for millions. In the non-Muslim world abroad he was described as the "virtual face of Islam in Western popular culture," known for his support of the hostage takers during the Iranian hostage crisis and his fatwa calling for the death of British citizen Salman Rushdie. TIME magazine described him as "a fanatic whose judgments are harsh, reasoning bizarre and conclusions surreal," and Iranian American scholar Vali Nasr as one who inculcated "fear and distrust towards Islam. Named Man of the Year in 1979 by American news magazine TIME, Khomeini has been referred to as a "charismatic leader of immense popularity," considered a "champion of Islamic revival" by Shia scholars. Khomeini is usually known as Imam Khomeini inside Iran and amongst his followers internationally, and Ayatollah Khomeini outside of the country.

Ayatollah Khomeini's paternal grandfather, Seyyed Ahmad Musavi Hindi, was born in Kintur, a village in the Barabanki District of Uttar Pradesh, India. He went to Iran in 1834 and settled down in Khomein, Iran, in 1839 during the times of British Raj in India to escape colonial rule. Ruhollah began to study the Qur'an, Islam's holiest book, and elementary Persian at age six. The following year, he began to attend a local school, where he learned mathematics, science, geography, and other traditional subjects. Throughout his childhood, he would continue his religious and secular education with the assistance of his relatives, including his mother's cousin, Ja'far, and his elder brother, Morteza Pasandideh.

After World War I arrangements were made for him to study at the Islamic seminary in Esfahan, but he was attracted instead to the seminary in Arak. He was placed under the leadership of Ayatollah Abdul Karim Haeri Yazdi. In 1920, Khomeini moved to Arak and commenced his studies. The following year, Ayatollah Haeri Yazdi transferred to the Islamic seminary at the holy city of Qom, southwest of Tehran, and invited his students to follow. Khomeini accepted the invitation, moved, and took up residence at the Dar al-Shafa school in Qom. Khomeini's studies included Islamic law (sharia) and jurisprudence (fiqh), but by that time, Khomeini had also acquired an interest in poetry and philosophy (irfan). So, upon arriving in Qom, Khomeini sought the guidance of Mirza Ali Akbar Yazdi, a scholar of philosophy and mysticism. Yazdi died in 1924, but Khomeini would continue to pursue his interest in philosophy with two other teachers, Javad Aqa Maleki Tabrizi and Rafi'i Qazvini. However, perhaps Khomeini's biggest influences were yet another teacher, Mirza Muhammad 'Ali Shahabadi, and a variety of historic Sufi mystics, including Mulla Sadra and Ibn Arabi. Ruhollah Khomeini was a lecturer at Najaf and Qum seminaries for decades before he was known in the political scene. He soon became a leading scholar of Shia Islam. He taught political philosophy, Islamic history and ethics. Several of his students (e.g. Morteza Motahhari) later became leading Islamic philosophers and also marja. As a scholar and teacher, Khomeini produced numerous writings on Islamic philosophy, law, and ethics. He showed an exceptional interest in subjects like philosophy and gnosticism that not only were usually absent from the curriculum of seminaries but were often an object of hostility and suspicion.
His seminary teaching often focused on the importance of religion to practical social and political issues of the day, and he worked against the outspoken advocacy of secularism in the 1940s. His first book, Kashf al-Asrar (Uncovering of Secrets) published in 1942, was a point-by-point refutation of Asrar-e hazar salih (Secrets of a Thousand Years), a tract written by a disciple of Iran's leading anti-clerical historian, Ahmad Kasravi. In addition, he went from Qom to Tehran to listen to Ayatullah Hasan Mudarris - the leader of the opposition majority in Iran's parliament during 1920s. Khomeini became a marja in 1963, following the death of Grand Ayatollah Seyyed Husayn Borujerdi.

Most Iranians had a deep respect for the Shi'a clergy or Ulema, and tended to be religious, traditional, and alienated from the process of Westernization pursued by the Shah. In the late 19th century the clergy had shown themselves to be a powerful political force in Iran initiating the Tobacco Protests against a concession to a foreign (British) interest. At the age of 61, Khomeini found the arena of leadership open following the deaths of Ayatollah Sayyed Husayn Borujerdi (1961), the leading, although quiescent, Shi'ah religious leader; and Ayatollah Abol-Ghasem Kashani (1962), an activist cleric. The clerical class had been on the defensive ever since the 1920s when the secular, anti-clerical modernizer Reza Shah Pahlavi rose to power. Reza's son Muhammad Reza Shah, instituted a "White Revolution," which was a further challenge to the ulama. In January 1963, the Shah announced the "White Revolution," a six-point programme of reform calling for land reform, nationalization of the forests, the sale of state-owned enterprises to private interests, electoral changes to enfranchise women and allow non-Muslims to hold office, profit-sharing in industry, and a literacy campaign in the nation's schools. Some of these initiatives were regarded as dangerous, Westernizing trends by traditionalists, especially by the powerful and privileged Shi'a ulama (religious scholars).

Ayatollah Khomeini summoned a meeting of the other senior marjas of Qom and persuaded them to decree a boycott of the referendum on the White Revolution. On 22 January 1963 Khomeini issued a strongly worded declaration denouncing the Shah and his plans. Two days later the Shah took an armored column to Qom, and delivered a speech harshly attacking the ulama as a class. Khomeini continued his denunciation of the Shah's programmes, issuing a manifesto that bore the signatures of eight other senior Iranian Shia religious scholars. In it he listed the various ways in which the Shah had allegedly violated the constitution, condemned the spread of moral corruption in the country, and accused the Shah of submission to America and Israel. He also decreed that the Nowruz celebrations for the Iranian year 1342 (which fell on 21 March 1963) be canceled as a sign of protest against government policies. On the afternoon of 'Ashura (3 June 1963), Khomeini delivered a speech at the Feyziyeh madrasah drawing parallels between the infamous tyrant Yazid and the Shah, denouncing the Shah as a "wretched, miserable man," and warning him that if he did not change his ways the day would come when the people would offer up thanks for his departure from the country. On 5 June 1963, (15 of Khordad), two days after this public denunciation of the Shah Mohammad Reza Pahlavi, Khomeini was arrested. This sparked three days of major riots throughout Iran and led to the deaths of some 400. That event is now referred to as the Movement of 15 Khordad. Khomeini was kept under house arrest and released in August ("A History of Iran" by Michael Axworthy).

During November 1964, Khomeini denounced both the Shah and the United States, this time in response to the "capitulations" or diplomatic immunity granted by the Shah to American military personnel in Iran. The famous "capitulation" law (or "status-of-forces agreement") would allow members of the U.S. armed forces in Iran to be tried in their own military courts. Khomeini was arrested in November 1964 and held for half a year. Upon his release, he was brought before Prime Minister Hasan Ali Mansur, who tried to convince Khomeini that he should apologize and drop his opposition to the government. Khomeini refused. In fury, Mansur slapped Khomeini's face. Two weeks later, Mansur was assassinated on his way to parliament. Four members of the Fadayan-e Islam were later executed for the murder.

Khomeini studied Greek Philosophy and was influenced by both the philosophy of Aristotle, whom he regarded as the founder of logic, and Plato, whose views "in the field of divinity" he regarded as "grave and solid". Among Islamic philosophers, Khomeini was mainly influenced by Avicenna and Mulla Sadra. Apart from philosophy, Khomeini was also interested in literature and poetry. His poetry collection was released after his death. Beginning in his adolescent years, Khomeini composed mystic, political and social poetry. His poetry works were published in three collections The Confidant, The Decanter of Love and Turning Point and Divan. Some of his poems are even seen as criticizing spirituality and religion, like the one who was firstly dedicated to a commander in Iran-Iraq war but which was published by his son as a memorial to him. He even claims the controversial "I am the Truth" of the Persian mystic Manṣūr al-Ḥallāj and uses the Ṣūfīterminology of wine for instance.

Khomeini spent more than 14 years in exile, mostly in the holy Shia city of Najaf, Iraq. Initially he was sent toTurkey on 4 November 1964 where he stayed in the city of Bursa for less than a year. He was hosted by a colonel in Turkish Military Intelligence named Ali Cetiner in his own residence, who could not find another accommodation alternative for his stay at the time. Later in October 1965 he was allowed to move to Najaf, Iraq, where he stayed until being forced to leave in 1978, after then Vice President Saddam Hussein told him that it's better to leave (the two countries would fight a bitter eight year war 1980–1988 only a year after the two reached power in 1979) after which he went to Neauphle-le-Château in France on a tourist visa, apparently not seeking political asylum, where he stayed for four months. According to Alexandre de Marenches, chief of External Documentation and Counter-Espionage Service (now known as the DGSE), the shah declined that France expelled Khomeini for fear that the cleric should move to Syria or Libya. Some sources report that president Valéry Giscard d' Estaing sent Michel Poniatowski to Teheran to propose to the Shah the elimination of Khomeini.

By the late 1960s, Khomeini was a marja-e taqlid (model for imitation) for "hundreds of thousands" of Shia, one of six or so models in the Shia world. While in the 1940s Khomeini accepted the idea of a limited monarchy under the Iranian Constitution of 1906–1907 — as evidenced by his book Kashf al-Asrar — by the 1970s he rejected the idea. In early 1970, Khomeini gave a series of lectures in Najaf on Islamic government, later published as a book titled variously Islamic Government or Islamic Government: Authority of the Jurist (Hokumat-e Islami: Velayat-e faqih). This was his most famous and influential work, and laid out his ideas on governance (at that time):

• That the laws of society should be made up only of the laws of God (Sharia), which cover "all human affairs" and "provide instruction and establish norms" for every "topic" in "human life."
• Since Shariah, or Islamic law, is the proper law, those holding government posts should have knowledge of Sharia. Since Islamic jurists or faqih have studied and are the most knowledgeable in Sharia, the country's ruler should be a faqih who "surpasses all others in knowledge" of Islamic law and justice, (known as a marja'), as well as having intelligence and administrative ability. Rule by monarchs and/or assemblies of "those claiming to be representatives of the majority of the people" (i.e. elected parliaments and legislatures) has been proclaimed "wrong" by Islam.
• This system of clerical rule is necessary to prevent injustice, corruption, oppression by the powerful over the poor and weak, innovation and deviation of Islam and Sharia law; and also to destroy anti-Islamic influence and conspiracies by non-Muslim foreign powers.

A modified form of this wilayat al-faqih system was adopted after Khomeini and his followers took power, and Khomeini was the Islamic Republic's first "Guardian" or Supreme Leader.

In the meantime, however, Khomeini was careful not to publicize his ideas for clerical rule outside of his Islamic network of opposition to the Shah which he worked to build and strengthen over the next decade. In Iran, a number of actions of the shah including his repression of opponents began to build opposition to his regime. Cassette copies of his lectures fiercely denouncing the Shah as (for example) "... the Jewish agent, the American serpant whose head must be smashed with a stone", became common items in the markets of Iran, helped to demythologize the power and dignity of the Shah and his reign. Aware of the importance of broadening his base, Khomeini reached out to Islamic reformist and secular enemies of the Shah, despite his long-term ideological incompatibility with them.

After the 1977 death of Dr. Ali Shariati (an Islamic reformist and political revolutionary author/academic/philosopher who greatly popularized the Islamic revival among young educated Iranians), Khomeini became the most influential leader of the opposition to the Shah. Adding to his mystique was the circulation among Iranians in the 1970s of an old Shia saying attributed to the Imam Musa al-Kadhem. Prior to his death in 799, al-Kadhem was said to have prophesied that "A man will come out from Qom and he will summon people to the right path". In late 1978, a rumour swept the country that Khomeini's face could be seen in the full moon. Millions of people were said to have seen it and the event was celebrated in thousands of mosques. He was perceived by many Iranians as the spiritual, if not political, leader of revolt. As protest grew so did his profile and importance. Although thousands of kilometers away from Iran in Paris, Khomeini set the course of the revolution, urging Iranians not to compromise and ordering work stoppages against the regime. During the last few months of his exile, Khomeini received a constant stream of reporters, supporters, and notables, eager to hear the spiritual leader of the revolution.

Khomeini had refused to return to Iran until the Shah left. On 17 January 1979, the Shah did leave the country (ostensibly "on vacation"), never to return. Two weeks later, on Thursday, 1 February 1979, Khomeini returned in triumph to Iran, welcomed by a joyous crowd estimated at least six million by ABC News reporter Peter Jennings, who was reporting the event from Tehran. On the Air France flight on his way to Iran, Khomeini was asked by Jennings: "What do you feel in returning to Iran?" Khomeini answered "Hichi" (nothing). This statement was considered reflective of his mystical or puritanical belief that Dar al-Islam, rather than the motherland, was what mattered, and also a warning to Iranians who hoped he would be a "mainstream nationalist leader" that they were in for disappointment.

Khomeini adamantly opposed the provisional government of Shapour Bakhtiar, promising "I shall kick their teeth in. I appoint the government. I appoint the government by support of this nation." On 11 February [(Bahman 22)], Khomeini appointed his own competing interim prime minister, Mehdi Bazargan, demanding, "since I have appointed him, he must be obeyed." It was "God's government," he warned, disobedience against which was a "revolt against God." As Khomeini's movement gained momentum soldiers began to defect to his side, and Khomeini declared jihad on soldiers who did not surrender. On 11 February [(Bahman 22)], as revolt spread and armories were taken over, the military declared neutrality and the Bakhtiar regime collapsed. On 30 March 1979, and 31 March 1979, a referendum to replace the monarchy with an Islamic Republic passed with 98% voting in favour of the replacement. Although revolutionaries were now in charge and Khomeini was their leader, several secular and religious groups were unaware of Khomeini's plan for Islamic government by wilayat al-faqih, which involved rule by a marja' Islamic cleric. This provisional constitution for the Islamic Republic did not include the post of supreme Islamic clerical ruler.

Khomeini and his supporters worked to suppress some former allies and rewrote the proposed constitution. Some newspapers were closed, and those protesting the closings were attacked. Opposition groups such as the National Democratic Front and Muslim People's Republican Party were attacked and finally banned. Through popular support and with charges of questionable balloting, Khomeini supporters gained an overwhelming majority of the seats of the Assembly of Experts which revised the proposed constitution. The newly proposed constitution included an Islamic jurist Supreme Leader of the country, and a Council of Guardians to veto un-Islamic legislation and screen candidates for office, disqualifying those found un-Islamic. In November 1979, the new constitution of the Islamic Republic was adopted by national referendum. Khomeini himself became instituted as the Supreme Leader (supreme jurist ruler), and officially became known as the "Leader of the Revolution." On 4 February 1980, Abolhassan Banisadr was elected as the first president of Iran.

On 22 October 1979 the United States admitted the exiled and ailing Shah into the country for cancer treatment. In Iran there was an immediate outcry with both Khomeini and leftist groups demanding the Shah's return to Iran for trial and execution. Revolutionaries were reminded of Operation Ajax, 26 years earlier when the Shah fled abroad while American CIA and British intelligence organized a coup d'état to overthrow his nationalist opponent. On 4 November, Islamist students calling themselves Muslim Student Followers of the Imam's Line took control of the American Embassy in Tehran, holding 52 embassy staff hostage for 444 days – an event known as the Iran hostage crisis. In 2005, when Mahmoud Ahmedinejad became president, several of the hostages identified him as one of their captors, although he denied it. In America, the hostage-taking was seen as a flagrant violation of international law and aroused intense anger and anti-Iranian sentiments. In Iran the takeover was immensely popular and earned the support of Khomeini under the slogan "America can't do a damn thing against us." The seizure helped to advance the cause of theocratic government and outflank politicians and groups who emphasized stability and normalized relations with other countries. Khomeini is reported to have told his president: "This action has many benefits ... this has united our people. Our opponents do not dare act against us. We can put the constitution to the people's vote without difficulty, and carry out presidential and parliamentary elections." The new theocratic constitution was successfully passed by referendum a month after the hostage crisis began. The effect was the splitting of the opposition into two groups – radicals supporting the hostage taking, and the moderates who opposed it. On 23 February 1980, Khomeini proclaimed Iran's Majlis would decide the fate of the American embassy hostages, and demanded that the United States hand over the Shah for trial in Iran for crimes against the nation. Although the Shah died a few months later, during the summer, the crisis continued. In Iran, supporters of Khomeini named the embassy a "Den of Espionage", publicizing details regarding armaments, espionage equipment and many volumes of official and classified documents which they found there.

Khomeini believed in Muslim unity and solidarity and the export of Islamic revolution throughout the world. "Establishing the Islamic state world-wide belong to the great goals of the revolution." He declared the birth week of Muhammad (the week between 12th to 17th of Rabi' al-awwal) as the Unity week. Then he declared the last Friday of Ramadan as International Day of Quds in 1981. Despite his devotion to Islam, Khomeini also emphasized international revolutionary solidarity, expressing support for the PLO, the IRA, Cuba, and the South African anti-apartheid struggle. Shortly after assuming power, Khomeini began calling for Islamic revolutions across the Muslim world, including Iran's Arab neighbor Iraq, the one large state besides Iran with a Shia majority population. At the same time Saddam Hussein, Iraq's secular Arab nationalist Ba'athist leader, was eager to take advantage of Iran's weakened military and (what he assumed was) revolutionary chaos, and in particular to occupy Iran's adjacent oil-rich province of Khuzestan, and, of course, to undermine Iranian Islamic revolutionary attempts to incite the Shi'a majority of his country.

With what many Iranians believe was the encouragement of the United States, Saudi Arabia and other countries, in September 1980 Iraq launched a full scale invasion of Iran, starting what would become the eight-year-long Iran–Iraq War (September 1980 – August 1988). A combination of fierce resistance by Iranians and military incompetence by Iraqi forces soon stalled the Iraqi advance and by early 1982 Iran regained almost all the territory lost to the invasion. The invasion rallied Iranians behind the new regime, enhancing Khomeini's stature and allowed him to consolidate and stabilize his leadership. After this reversal, Khomeini refused an Iraqi offer of a truce, instead demanding reparation and toppling of Saddam Hussein from power. Although Iran's population and economy were three times the size of Iraq's, the latter was aided by neighbouring Gulf Arab states, as well as the Soviet Bloc and Western countries. The Gulf Arabs and the West wanted to be sure the Islamic revolution did not spread across the Persian Gulf while the Soviet Union was concerned about the potential threat posed to its rule in central Asia to the north. The war continued for another six years, its costs mounting. 1988 saw deadly month-long Iraqi missile attacks on Tehran, mounting economic problems, the demoralization of Iranian troops, attacks by the American Navy on Iranian ships and oil rigs in the Persian Gulf, and the recapture by Iraq of the Faw peninsula. In July of that year, Khomeini, in his words, "drank the cup of poison" and accepted a truce mediated by the United Nations. Despite the high cost of the war – 450,000 to 950,000 Iranian casualties and USD $300 billion – Khomeini insisted that extending the war into Iraq in an attempt to overthrow Saddam had not been a mistake. In a 'Letter to Clergy' he wrote: '... we do not repent, nor are we sorry for even a single moment for our performance during the war. Have we forgotten that we fought to fulfill our religious duty and that the result is a marginal issue?'

In early 1989, Khomeini issued a fatwa calling for the assassination of Salman Rushdie, an India-born British author. Khomeini claimed that Rushdie's assassination was a religious duty for Muslims because of his alleged blasphemy against Muhammad in his novel, The Satanic Verses, published in 1988. Rushdie's book contains passages that many Muslims – including Ayatollah Khomeini – considered offensive to Islam and the prophet, but the fatwa has also been attacked for violating the rules of fiqh by not allowing the accused an opportunity to defend himself, and because "even the most rigorous and extreme of the classical jurist only require a Muslim to kill anyone who insults the Prophet in his hearing and in his presence." Though Rushdie publicly apologized, the fatwa was not revoked. Khomeini explained,

Even if Salman Rushdie repents and becomes the most pious man of all time, it is incumbent on every Muslim to employ everything he has got, his life and wealth, to send him to Hell.

Rushdie himself was not killed but Hitoshi Igarashi, the Japanese translator of the book The Satanic Verses, was murdered and two other translators of the book survived murder attempts.

In a speech given to a huge crowd after returning to Iran from exile 1 February 1979, Khomeini made a variety of promises to Iranians for his coming Islamic regime: A popularly elected government that would represent the people of Iran and with which the clergy would not interfere. He promised that "no one should remain homeless in this country," and that Iranians would have free telephone, heating, electricity, bus services and free oil at their doorstep. While many changes came to Iran under Khomeini, these promises have yet to be fulfilled in the Islamic Republic.

Under Khomeini's rule, Sharia (Islamic law) was introduced, with the Islamic dress code enforced for both men and women by Islamic Revolutionary Guards and other Islamic groups. Women were required to cover their hair, and men were not allowed to wear shorts. Alcoholic drinks, most Western movies, the practice of men and women swimming or sunbathing together were banned. The Iranian educational curriculum was Islamized at all levels with the Islamic Cultural Revolution; the "Committee for Islamization of Universities" carried this out thoroughly. The broadcasting of any music other than martial or religious on Iranian radio and television was banned by Khomeini on July 1979. The ban lasted 10 years (approximately the rest of his life).

Khomeini is said to have stressed "the spiritual over the material". Six months after his first speech he expressed exasperation with complaints about the sharp drop in Iran's standard of living: 'I cannot believe that the purpose of all these sacrifices was to have less expensive melons'  On another occasion emphasizing the importance of martyrdom over material prosperity: "Could anyone wish his child to be martyred to obtain a good house? This is not the issue. The issue is another world." He is also reportedly famous for answering a question about his economic policies by declaring that 'economics is for donkeys'. This low opinion of economics is said to be "one factor explaining the inchoate performance of the Iranian economy since the revolution." Another factor was the long war with Iraq, whose cost led to government debt and inflation, eroding personal incomes, and unprecedented unemployment.

While Iran became more strict Islamically under Khomeini, absolute poverty rose by nearly 45% during the first 6 years of his rule. Emigration from Iran also developed, reportedly for the first time in the country's history. Since the revolution, an estimated "two to four million entrepreneurs, professionals, technicians, and skilled craftspeople (and their capital)" have emigrated to other countries.

Opposition to the religious rule of the clergy or Islamic government in general was often met with harsh punishments. In a talk at the Fayzieah School in Qom, 30 August 1979, Khomeini warned opponents: "Those who are trying to bring corruption and destruction to our country in the name of democracy will be oppressed. They are worse than Bani-Ghorizeh Jews, and they must be hanged. We will oppress them by God's order and God's call to prayer."

The Shah Mohammad Reza Pahlavi and his family left Iran and escaped harm, but hundreds of former members of the overthrown monarchy and military met their end in firing squads, with critics complaining of "secrecy, vagueness of the charges, the absence of defense lawyers or juries", or the opportunity of the accused "to defend themselves." In later years these were followed in larger numbers by the erstwhile revolutionary allies of Khomeini's movement — Marxists and socialists, mostly university students — who opposed the theocratic regime. In the 1988 massacre of Iranian prisoners, following the People's Mujahedin of Iran operation Forough-e Javidan against the Islamic Republic, Khomeini issued an order to judicial officials to judge every Iranian political prisoner and kill those who would not repent anti-regime activities. Estimates of the number executed vary from 1,400 to 30,000. Although many hoped the revolution would bring freedom of speech and press, this was not to be. In defending forced closing of opposition newspapers and attacks on opposition protesters by club-wielding vigilantes, Khomeini explained, 'The club of the pen and the club of the tongue is the worst of clubs, whose corruption is a 100 times greater than other clubs.'

Life for religious minorities was mixed under Khomeini. Non-Muslim religious minorities no longer had equal rights. Senior government posts are reserved for Muslims. Schools set up by Jews, Christians and Zoroastrians must be run by Muslim principals. Compensation for death paid to the family of a non-Muslim was (by law) less than if the victim was a Muslim. Conversion to Islam is encouraged by entitling converts to inherit the entire share of their parents (or even uncle's) estate if their siblings (or cousins) remain non-Muslim. Iran's non-Muslim population has fallen dramatically. For example, the Jewish population in Iran dropped from 80,000 to 30,000 in the first two decades of the revolution. However, four of the 270 seats in parliament are reserved for three non-Islamic minority religions, under the Islamic constitution that Khomeini oversaw. Khomeini also has called for unity between Sunni and Shi'a Muslims (Sunni Muslims are the largest religious minority in Iran). Prerevolutionary statements by Khomeini had been antagonistic towards Jews, but shortly after his return from exile in 1979, he issued a fatwa ordering that Jews and other minorities (except Bahá'ís) be treated well. In power, Khomeini distinguished between Zionism as a secular political party that employs Jewish symbols and ideals and Judaism as the religion of Moses. Unlike the other non-Muslims in Iran, the 300,000 members of the Bahá'í Faith, were actively harassed. "Some 200 of whom have been executed and the rest forced to convert or subjected to the most horrendous disabilities." Starting in late 1979 the new government systematically targeted the leadership of the Bahá'í community by focusing on the Bahá'í National Spiritual Assembly (NSA) and Local Spiritual Assemblies (LSAs); prominent members of NSAs and LSAs were either killed or disappeared. Like most conservative Muslims, Khomeini believed Bahá'í to be apostates. He claimed they were a political rather than a religious movement, declaring:

the Baha'is are not a sect but a party, which was previously supported by Britain and now the United States. The Baha'is are also spies just like the Tudeh [Communist Party].
