The 2009 Iranian presidential election protests marked a turning point in the history of Iran’s Islamic Republic. After the Islamic Revolution of 1979 the new government billed itself as democratic, but in the 1980s a conservative faction of Shiʿi Muslim clerics, led especially by the hawkish revolutionary figure Ali Khamenei, used the instability in Iran and the existential Iran-Iraq War (1980–88) to entrench their power. The government nonetheless maintained a facade of democracy in the 1990s and the early 2000s, reaching its peak under the reformist Pres. Mohammad Khatami (1997–2005). The presidential election of 2005, which brought to power the controversial conservative Pres. Mahmoud Ahmadinejad (2005–13), showed signs of interference. But the irregularities in the 2009 election were undeniable, prompting the government to concede to a partial recount but nonetheless certify a victory for Ahmadinejad. When Iranians took to the streets to challenge the results, they were met with a crackdown that demonstrated the supremacy of the military branch loyal to Khamenei, the Islamic Revolutionary Guard Corps (IRGC), over the Iranian people. The protests—then the largest seen in Iran since the 1979 revolution—were eventually quelled, and election interference became increasingly apparent in the years ahead. The inability of Iranians to decide their future through the polls led them periodically to the streets in future years, each time met with a brutal response.
The presidential election
In the lead-up to the 2009 presidential election, Ahmadinejad appeared at particular risk of being unseated by one of his centrist challengers, former prime minister Mir Hossein Mousavi, around whom many of the country’s centrists and reformists had coalesced. Voter turnout at the election in mid-June was estimated to reach record highs (polling hours were extended four times to accommodate the turnout), a factor that some interpreted as favorable to Mousavi. Shortly after the polls closed, Mousavi—who claimed he had been contacted by the interior ministry to inform him of his victory—announced that he had won the election outright by a large margin; shortly thereafter, however, officials made a similar announcement in favor of Ahmadinejad. Although Ahmadinejad insisted that the election had been fair and that his mandate had been broadened by the large turnout and the scope of his victory, his opponents alleged electoral fraud. Mousavi urged his supporters to protest the results, and, in the days following the election, massive demonstrations unfolded in the capital and elsewhere. He was joined by Mehdi Karroubi, another candidate for president who received a much smaller portion of the vote. Although Khamenei, the supreme leader, initially upheld the election results, he subsequently called for an official inquiry by the Council of Guardians into the allegations of electoral irregularities. The decision was quickly followed by an announcement by the Council of Guardians that the vote would be subject to a partial recount, a motion that fell short of the annulment the opposition had sought.
Suppression and crackdown
On June 19, following nearly a week of opposition demonstrations against the election results, Khamenei issued his first public response to the unrest: before a crowd of supporters at Friday prayers, he again backed Ahmadinejad’s victory and warned the opposition against further demonstrations. Subsequent protests were greeted with increasing brutality. On June 22 the Council of Guardians confirmed that 50 constituencies had returned more votes than there were registered voters, bearing the potential to affect some three million votes in the final tally, but the council indicated that this would not be enough to change the outcome of the election. Although the opposition identified similar problems in three times that number of constituencies, the council confirmed Ahmadinejad’s victory following the completion of a partial recount. Days before Ahmadinejad’s second inauguration, state television broadcast a mass show trial of more than 100 detainees.
Periodic demonstrations and protests, which became known as the Green Movement, persisted in the months that followed. Among the most notable opportunities was the funeral of Hossein Ali Montazeri, one of the highest-ranking Shiʿi clerics who was at one time the designated successor to the supreme leader, but who became a vocal critic of Khamenei after he became supreme leader instead. Days later a larger and more widespread protest took place during the public observances of ʿĀshūrāʾ, a Shiʿi holiday mourning the martyrdom of Al-Ḥusayn ibn ʿAlī. Government forces fired on crowds of protesters and killed several people, including a nephew of Mousavi. Although the protest movement sought to rally on February 11, 2010, the anniversary of the Islamic Revolution, the movement was unable to organize effectively amid the crowds of government supporters, a discouraging failure that observers attributed to a lack of clear leadership. The following February, as the Arab Spring inspired renewed protests in Iran, the government took swift action against the opposition, including placing Mousavi and Karroubi under house arrest.
The movement effectively came to an end in 2011, but Iranians’ grievances continued to grow. Protests continued to take place, becoming nearly an annual occurrence by the end of the 2010s. In 2022 the death of Jina Mahsa Amini triggered the most sustained and unified challenge to the government since 2009, but that movement was eventually suppressed in 2023. When protests broke out in late 2025 over the collapse of the rial, the opposition was more fragmented, but the threat of foreign intervention by the United States or Israel added new coercive weight to the unrest.
