Every year on 11th February, Iran marks Islamic Revolution Day, known in Persian as the Anniversary of the Islamic Revolution or “22 Bahman” (the 22nd day of Bahman in the Iranian calendar). This national holiday commemorates one of the most significant political transformations of the 20th century: the events of 11th February, 1979, when the monarchy was overthrown and replaced with an Islamic Republic. The day represents the culmination of widespread popular protests that fundamentally reshaped Iran’s political, social, and cultural landscape.
Historical Context: The Fall of the Pahlavi Dynasty
To understand Islamic Revolution Day, one must first understand the circumstances that led to the revolution. Iran had been ruled by the Pahlavi dynasty since 1925, with Mohammad Reza Pahlavi serving as Shah (king) from 1941 until 1979. The Shah’s rule, particularly in its later years, was characterised by modernisation programs, close alignment with Western powers (especially the United States), and increasingly authoritarian governance.
A pivotal moment in Iran’s modern history occurred in 1953 when a coup d’état, backed by the CIA and British intelligence, overthrew Iran’s democratically elected Prime Minister Mohammad Mossadegh, who had nationalised the country’s oil industry. The coup reinstated the Shah as an absolute monarch and significantly increased American influence over Iran. This foreign intervention would become a rallying point for revolutionary sentiment in the years to come.
In 1963, the Shah launched the White Revolution, a top-down modernisation and land reform program intended to transform Iran into a modern industrial power. While these reforms brought economic growth and modernization, they also alienated many sectors of Iranian society. The clergy saw the reforms as a threat to Islamic values and their traditional social role. The urban middle class desired democratic reforms rather than imposed modernisation. Economic inequality persisted despite growth, and the regime’s repressive tactics, enforced by the secret police service SAVAK, created widespread resentment.
The Revolutionary Movement Takes Shape
By the late 1970s, a diverse coalition of opposition groups had formed against the Shah’s rule. This coalition included religious conservatives led by Ayatollah Ruhollah Khomeini, secular liberals who wanted constitutional democracy, leftist groups including the Tudeh Party, and various guerrilla organisations. What united these disparate groups was their opposition to the Shah’s authoritarianism and the perception of excessive Western interference in Iranian affairs.
Khomeini, a prominent Shia cleric who had been exiled in 1964 for his opposition to the Shah’s reforms, emerged as the revolution’s most influential leader. From exile, first in Iraq and later in France, Khomeini coordinated opposition activities and articulated a vision for an Islamic government that resonated with millions of Iranians. His message combined religious authority with anti-imperialist rhetoric, appealing to both traditional religious conservatives and those who opposed Western influence.’
Throughout 1978, protests and demonstrations escalated across Iran. The government’s violent responses to peaceful demonstrations only fuelled further outrage. As the situation deteriorated, the Shah appointed Shapour Bakhtiar, a secular opposition figure, as Prime Minister in a last-ditch effort to preserve the monarchy through reform. However, Bakhtiar’s appointment came too late and with insufficient authority to stem the revolutionary tide.
The Ten Days That Changed Iran
On January 16, 1979, Shah Mohammad Reza Pahlavi left Iran in what was officially described as a “vacation,” though it was clear to most observers that he would not return. His departure marked the effective end of 2,500 years of monarchical rule in Persia. Just over two weeks later, on 1st February 1979, Ayatollah Khomeini returned to Iran after nearly 15 years in exile, arriving at Tehran’s airport aboard a chartered Air France Boeing 747.
The scene at Khomeini’s arrival was extraordinary. Crowds of several million people gathered to welcome him, forcing his entourage to use a helicopter when the car from the airport became overwhelmed by enthusiastic supporters. People greeted him with cries of “Khomeini, O Imam, we salute you, peace be upon you,” and chanted “Islam, Islam, Khomeini, We Will Follow You.” Some even proclaimed “Khomeini for King,” though he would establish a very different form of government. When a reporter asked how he felt returning home after such a long exile, Khomeini’s famously terse reply was simply: “Nothing.”
The period from 1st to 11th February would become known as the “Decade of Fajr” (Ten Days of Dawn), a time of intense political upheaval and street protests. Khomeini quickly moved to consolidate power, appointing Mehdi Bazargan as Prime Minister of a provisional government even as Bakhtiar still officially held the position. The competing claims to legitimate authority created a constitutional crisis.
On 10th February, 1979, the situation reached a critical point. Revolutionary forces armed civilians and called for people to defy a government-imposed curfew. Khomeini urged his supporters to break the curfew, and they responded in massive numbers. Street fighting erupted between revolutionaries and forces loyal to the government. Revolutionary forces overwhelmed police stations, prisons, and government buildings across the country.
The decisive moment came on 11th February, 1979, when Iran’s military high command announced that the armed forces would remain neutral in the political conflict. This declaration effectively ended any hope for the preservation of the monarchy. Senior military commanders, recognizing that continuing to fight would split the army and cause massive bloodshed, ordered troops to return to their barracks. Bakhtiar resigned and went into hiding (he later fled to Paris). By the end of the day, revolutionary forces controlled Tehran and other major cities. The monarchy had fallen, and a new era had begun.
Establishing the Islamic Republic
The revolution’s victory on 11th February was followed by months of political consolidation. In March and April 1979, a national referendum was held asking Iranians whether they supported replacing the monarchy with an Islamic Republic. According to official results, the measure passed with overwhelming support. A new constitution was drafted, establishing a unique system of government combining republican elements with religious authority vested in a Supreme Leader.
Khomeini became Iran’s first Supreme Leader, a position he would hold until his death in 1989. The new government quickly moved to implement Islamic law and consolidate power, often side lining the secular and leftist groups that had participated in the revolution. What had begun as a broad-based coalition movement ultimately resulted in the establishment of a theocratic state under clerical rule.
How Islamic Revolution Day Is Celebrated
Islamic Revolution Day is marked throughout Iran with state-sponsored celebrations and demonstrations. The commemoration is the culmination of the Ten-Day Fajr period, which begins on 1st February with events marking Khomeini’s return from exile and builds toward the main celebration on 11th February.
The celebrations typically include large rallies and marches through the boulevards of Iranian cities. In Tehran, demonstrators gather at Azadi (Liberty) Square, an iconic monument built during the Shah’s era but renamed after the revolution’s victory. Government officials deliver speeches emphasizing the revolution’s achievements and its ongoing relevance. The day is filled with patriotic and religious slogans, banners displaying revolutionary messages, and crowds waving Iranian flags.
Evening firework displays illuminate cities across the country. State television broadcasts special programming highlighting the revolution’s history and its impact on Iran. The government uses the occasion to showcase military strength and technological achievements, often including parades or displays of military equipment.
The period also coincides with cultural events. The Fajr International Film Festival, organized by the Ministry of Culture and Islamic Guidance, has been held annually since 1982 during the Ten-Day Fajr. It is Iran’s largest public film, theatre, and music festival.
Government attendance at these celebrations is essentially mandatory for officials, and there is often significant pressure on public employees and students to participate. The state presents these events as demonstrations of popular support for the Islamic Republic and its values.
A Day of Contested Meanings
While Islamic Revolution Day remains an important national observance, its meaning and the nature of its celebration have evolved considerably over the decades. The day has become a focal point for competing visions of Iran’s future, with some Iranians viewing it as a celebration of national sovereignty and Islamic values, while others see it as a reminder of promises unfulfilled and freedoms lost.
In recent years, the anniversary has frequently been accompanied by protests and counter-demonstrations. The 2009 disputed presidential election sparked the Green Movement, leading to significant opposition demonstrations during the 2010 anniversary. Opposition leaders at the time called for protests on 11th February, challenging the government’s narrative and demanding political reforms. Thousands of pro-democracy activists gathered, often on the outskirts of regime-sponsored celebrations, chanting slogans critical of the government.
The death of Mahsa Amini in 2022, who died in custody after being arrested for allegedly wearing an improper hijab, sparked renewed nationwide protests and the “Woman, Life, Freedom” movement. These protests continued through the 2023 anniversary, when anti-regime hackers disrupted state television broadcasts during President Ebrahim Raisi’s address, replacing it with protest footage and calls for mass demonstrations. According to human rights organizations, the government’s response to these protests resulted in thousands of arrests and hundreds of deaths.
During the 2024 and 2025 anniversaries, reports indicated that many residents in Tehran and other major cities engaged in “home-chanting,” shouting anti-government slogans from their residences in response to official fireworks displays. Videos circulated on social media showing protesters in various cities chanting phrases translated as “Death to the dictator” and calling for the overthrow of the current leadership. Security forces reportedly responded with tear gas and shotgun pellets to disperse demonstrations.
International Dimensions
Islamic Revolution Day has significant international dimensions that extend beyond Iran’s borders. The revolution inspired Islamic movements worldwide and created the first modern Islamic state, fundamentally altering regional and global politics. The establishment of a Shia Islamic government in Iran prompted concerns among Sunni-majority nations and their leaders, contributing to ongoing sectarian tensions in the Middle East.
The Iranian diaspora marks the anniversary in diverse ways. Some expatriates gather to celebrate what they view as a moment of national liberation from foreign domination. Others organize protests against the Islamic Republic, calling for regime change and greater international support for human rights in Iran. These demonstrations occur in cities worldwide, from Los Angeles to Paris to Ottawa, often featuring calls for democratic governance and the end of theocratic rule.
The anniversary also serves as an occasion for the Iranian government to emphasize its foreign policy positions. Anti-American and anti-Israeli slogans have been regular features of official celebrations since 1979, reflecting the regime’s confrontational stance toward these countries. The traditional chant “Death to America,” which Iranian officials explain as referring to American policies rather than its people, has been a fixture of anniversary rallies for decades.
Legacy and Ongoing Significance
More than four decades after the events it commemorates, Islamic Revolution Day continues to hold profound significance for understanding contemporary Iran. The revolution fundamentally transformed Iranian society, replacing a secular monarchy with a theocratic republic, reorienting the country’s foreign policy away from the West, and establishing a unique governmental system combining elected and appointed religious leadership.
For supporters of the Islamic Republic, the day represents a moment of national sovereignty, religious revival, and resistance to foreign domination. They view the revolution as having freed Iran from Western imperialism and restored Islamic values to public life. The anniversary serves as an affirmation of the regime’s legitimacy and its founding principles.
For critics, both inside Iran and abroad, the day evokes more complex and often painful reflections. Many point to the revolution’s unfulfilled promises of democratic governance, the suppression of political dissent, economic challenges, and restrictions on personal freedoms, particularly for women and religious minorities. The gap between revolutionary aspirations and current realities has become a source of ongoing political tension.
The anniversary also raises questions about historical interpretation and collective memory. Different generations of Iranians have vastly different relationships with the revolution. Those who participated in or remember the events of 1979 often have personal memories that may differ from official narratives. Younger generations, born after the revolution, evaluate the Islamic Republic based on their lived experiences rather than revolutionary ideals.
Looking to the Future
As Iran continues to navigate complex domestic and international challenges, Islamic Revolution Day serves as an annual moment of reflection on the country’s past and future direction. The ongoing tensions between the government’s official celebrations and expressions of popular discontent highlight the contested nature of the revolution’s legacy.
The anniversary occurs against the backdrop of ongoing debates about Iran’s political system, economic challenges, relations with the international community, and the role of religion in public life. These debates reflect broader questions about the revolution’s success in achieving its stated goals and whether its original vision remains relevant to contemporary Iranian society.
For observers trying to understand Iran’s role in regional and global affairs, Islamic Revolution Day offers important insights. The ways in which different groups commemorate, protest, or ignore the anniversary reveal much about Iran’s internal dynamics and the competing visions for its future. The day remains not just a historical commemoration but an active site of political contestation and national self-examination.
Whether viewed as a moment of liberation or the beginning of a troubled era, the events of 11th February, 1979, undeniably changed Iran and the wider Middle East in ways that continue to resonate today. Islamic Revolution Day ensures that these transformative events remain part of ongoing conversations about power, identity, religion, and governance in the 21st century.
