The Iranian opposition consists of various political groups, movements and people who oppose and seek the overthrow of the government of the Islamic Republic and its system of theocratic clerical rule based on the doctrine of the Guardianship of the Islamic Jurist (Velayat-e Faqih).
The opposition to Iran's theocratic government is ideologically diverse and includes republicans, monarchists, secularists, nationalists, liberals, and communists. In addition to secular and nationalist currents, Islamist groups and dissident Shia clerics have criticised aspects of the Islamic Republic and its political structure, though most are part of the Iranian reformists, certain Sunni Islamist and Kurdish Islamist movements have also opposed the state for religious or political reasons.
Opposition activity occurs both inside Iran and among the Iranian diaspora. Within Iran, political opposition is highly repressed by the government, and many opposition organisations and figures operate abroad. Protests organized by the opposition were violently suppressed, and many opposition figures, such as Mir Hossein Mousavi and Zahra Rahnavard, were held under house arrest for years without any charges. Thousands of political opponents of the Iranian government were summarily executed in 1988. Since the start of the 2025-2026 protests, Iranian government has been carrying out executions on an almost daily basis. Analysts and activists debate the mechanism of transition, whether change is more likely to emerge from within existing structures, mass civil resistance, elite fragmentation, or abrupt systemic collapse.
The issue of foreign intervention remains contested while some perspectives emphasise diplomatic pressure, sanctions, and international support for human rights as necessary tools to weaken authoritarian structures. Others warn that overt external intervention, especially military involvement, could undermine legitimacy, provoke nationalist backlash, or destabilise the region further.
These debates are reflected in the diversity of opposition actors. For example, the National Council of Resistance of Iran (NCRI) has outlined a Ten-Point Plan proposing a structured, rights-based democratic framework. Reza Pahlavi, Iran's exiled crown prince, has advocated for a 200-page plan that proposes he would lead the country during an 800-day transition. According to Reuters, the extent of support for restoring the monarchy within Iran remains uncertain, while pro-monarchist groups are divided.
Periodic nationwide protests have challenged the authorities, including the 1999 student protests, the 2009 Green Movement and 2009 protests following disputed presidential elections, the 2017–2018 and 2019–2020 protests, the 2022–2023 protests that followed the death of Mahsa Amini in police custody, and the 2025–2026 protests, which have been the largest unrest since the 1979 Revolution. These movements often articulate demands that extend beyond formal political change, calling for broader cultural transformation, personal freedoms, and social justice. In this sense, democratisation is framed not only as a political project but also as a societal one, involving shifts in norms surrounding gender, authority, and individual rights. These demonstrations were met with large-scale security crackdowns, resulting in tens of thousands of deaths, injuries, and arrests.
Opposition during the Islamic Republic Early opposition
1979 revolution Following the Islamic Revolution of 1979 and the establishment of the Islamic Republic, opposition to the new political order soon emerged. On 8 March 1979, coinciding with International Women's Day, thousands of women and supporters demonstrated in Tehran and other cities against proposals by the new authorities to enforce compulsory Islamic dress for women in public. The demonstrations continued for several days and became one of the earliest large-scale public protests against policies introduced by the post-revolutionary government.
On 14 June 1980, Ruhollah Khomeini called for the "Islamisation" of universities and the removal of what he described as Western and secular influences from Iran's higher education system. This directive led to the Iranian Cultural Revolution, during which universities were closed from 1980 to 1983 while curricula were revised and academic staff and students were screened for ideological conformity. During this period, numerous academics, students, and administrators were dismissed or prevented from continuing their studies or employment on political or religious grounds.
In the years immediately following the revolution, a range of political organisations sought to mobilise support among students and young people, including the People's Mojahedin Organisation of Iran (MEK). Universities became important arenas of political contestation between supporters of the Islamic Republic and various opposition groups. The Cultural Revolution and broader efforts to reshape cultural and political life in accordance with Islamic principles contributed to restrictions on secular and left-wing organisations and provoked periodic protests within academic and intellectual circles.
1980 election tensions On the final day of the elections, Massoud Rajavi met with President Abolhassan Banisadr and complained that members and supporters of the Islamic Republican Party (IRP) were intimidating voters, disrupting campaign activities, and attacking opposition supporters. According to accounts from the MEK, incidents included the disruption of rallies, assaults on campaign workers, and interference with ballot boxes. Following the elections, the MEK leadership concluded that it possessed sufficient support to function as a political opposition, but that the ruling establishment would not permit it to operate freely. Tensions subsequently escalated between the MEK and the IRP, while the organisation initially refrained from direct criticism of Ayatollah Ruhollah Khomeini. Revolutionary institutions aligned with the new government increasingly restricted the activities of the MEK and other opposition groups.
Crackdown and escalation of violence After the dismissal and impeachment of President Abolhassan Banisadr by the Islamic Consultative Assembly in June 1981, the MEK called for nationwide demonstrations against the government on 20 June 1981. Large crowds gathered in several cities, estimates have suggested that the Tehran demonstration drew hundreds of thousands of participants. The protests were forcibly dispersed by security forces and pro-government groups, and the authorities subsequently launched a broad crackdown on the MEK and other opposition organisations. The events of June 1981 marked a turning point in the conflict between the Islamic Republic and armed opposition groups, leading to a period of violence, arrests, and executions during the early 1980s.
Later opposition activity In the following decades, opposition to the government in Iran continued to manifest through various protests and political movements. Notable examples include the and the 1999 Iranian student protests. In 2004, a number of Iranian political activists in exile, including Hassan Shariatmadari, established the United Republicans of Iran (URI), a political organisation advocating a secular and democratic political system for Iran.
Growing discontent
2009 Green Movement Widespread protests followed the 2009 Iranian presidential election, when protesters alleged that the government had committed electoral fraud. The protests became part of the Iranian Green Movement, At the time, the unrest was described by some observers as the largest in Iran since the 1979 Revolution.
During this period, Iranian women gained an increasingly prominent role in opposition activism, including campaigns against the country's mandatory hijab laws. In December 2017, a video of a woman removing and waving her hijab on a street in Tehran circulated widely on social media. The act inspired a series of similar protests in subsequent months, referred to as the Girls of Revolution Street.
Opposition Unity In November 2018, ten Iranian opposition organisations signed a joint memorandum of understanding intended to demonstrate unity despite internal divisions and to reaffirm their support for the overthrow of the Islamic Republic. The signatories expressed support for establishing a parliamentary democracy and for the separation of religion and state. The groups included the Republican Movement of Iran, Democratic Party of Iranian Kurdistan, Kurdistan Democratic Party, Komalah, Union of People's Fedaian of Iran, Komala of the Toilers of Kurdistan, , Ahvaz Democratic Solidarity Party, Provisional Council of Left Socialists of Iran and the Democratic Alliance
On 12 June 2019, the tenth anniversary of the 2009 Iranian presidential election, 14 opposition activists based both inside and outside Iran signed an open letter known as the Statement of 14 Political Activists. The statement proposed a series of political and civil demands, including greater protection for women's rights, increased independence between the branches of government, amendments to the Constitution of Iran, and the resignation of supreme leader Ali Khamenei. Similar letters were published by other activists in August 2019, leading to a number of arrests.
In October 2020, Reza Pahlavi issued a message titled "New Pact", emphasising the rejection of the monopoly of power. He called for stronger connections between acts of civil disobedience throughout the country, including protests and strikes. He also called on all pro-democracy political forces to set aside their differences and unite for the transition from the Islamic Republic. Abdulla Mohtadi, Secretary General of the Komala Party of Iranian Kurdistan and a member of the , considered this message a positive first step, but did not consider it sufficient for unity among the opposition. Mojtaba Vahedi viewed Pahlavi's message positively, and commended his opposition to individual rule; however, Vahedi criticised Pahlavi's claim about his lack of desire for political power, asserting that political power is needed to implement political activity. He further called on Pahlavi to deal with those who create discord among the Iranian opposition to avoid prolonging the Islamic Republic. Ammar Maleki, a professor of political science in the Netherlands, assessed this move as positive and promising, but believed that more practical action is required.
In September 2022, widespread protests erupted across Iran following the death of Mahsa Amini, who was killed after her arrest for wearing the hijab "improperly". On 3 February 2023, former Prime Minister and reformist leader of the Green Revolution Mir-Hossein Mousavi called for a referendum on an end to clerical rule, stating that "he no longer supports the current Islamic Republic constitution". Over 400 political activists and journalists signed a statement where Mousavi called for the creation of a constituent assembly and a new constitution, believing that "with the current social awakening, and the society's disillusionment with reforms within the current political structure, there is no other way than allowing the people to decide their own destiny." This shift brings Mousavi in line with other opposition voices in its call for transition away from the Islamic Republic, and has support from Pahlavi, who reiterated the need for unity among opponents of the Islamic Republic government. Iran's top Sunni cleric Abdolhamid Ismaeelzahi also supported the initiative, saying, "Mousavi showed that he understood the realities of society. It's time for other politicians and ulema to think about saving the country and see the facts."
