The Iran hostage crisis began on 4 November 1979, when Iranian students loyal to Ayatollah Khomeini stormed the United States embassy in Tehran. Fifty-two American diplomats and citizens were held for 444 days, until 20 January 1981. The crisis broke diplomatic relations between Iran and the United States, which have not been restored, and helped the clerical camp take control of the revolution.

Why the students took the embassy
On 22 October 1979 the deposed shah, who was seriously ill with cancer, was admitted to the United States for treatment. For many Iranians this revived memories of the 1953 coup, organised with the CIA, and they feared Washington was preparing to restore him. On 1 November Prime Minister Mehdi Bazargan met President Carter’s national security adviser, Zbigniew Brzezinski, in Algiers, which radicals in Tehran saw as proof that the provisional government was too close to America.
A group of students from Tehran universities, calling themselves the Muslim Student Followers of the Imam’s Line, planned the takeover with the cleric Mohammad Mousavi Khoeiniha. They later said they intended a sit-in of a few days. On the morning of 4 November several hundred climbed the walls and gates, and the small Marine guard was ordered not to shoot.

Khomeini’s endorsement and Bazargan’s fall
Khomeini had not been told in advance, according to most accounts, but he quickly endorsed the action, calling it a second revolution greater than the first. The students called the embassy a “den of spies” and began publishing the documents they had found, including shredded papers they painstakingly pieced together. These were eventually printed in dozens of volumes and used against Iranian politicians who had had contacts with American officials.
Bazargan, unable to free the hostages or control the students, resigned with his cabinet on 6 November. Power passed to the Revolutionary Council, dominated by clerics. Shaul Bakhash and Ervand Abrahamian both argue that the crisis served the Islamic Republic Party well: it allowed the clerics to cast the liberals and the left as soft on America and to push through the new constitution in a referendum held in December, in the middle of the crisis (see the 1979 referendum and the new constitution).
The hostages
Sixty-three people were seized at the embassy and three more, including the chargé d’affaires Bruce Laingen, were held at Iran’s Foreign Ministry, where they had gone for a meeting. In mid-November Khomeini ordered the release of thirteen women and African-Americans, saying they were victims of American oppression themselves. Richard Queen was freed in July 1980 when he developed multiple sclerosis. The remaining 52 were moved between locations, sometimes blindfolded and paraded before cameras. Several later described beatings, mock executions and long periods of solitary confinement.
Six Americans had escaped from a consular building on the first day and hid in the homes of Canadian diplomats. In January 1980 they left Iran on Canadian passports with help from the CIA, an episode later dramatised in the film Argo (2012).
Sanctions and the failed rescue
The United States froze Iranian assets, stopped buying Iranian oil and on 7 April 1980 broke diplomatic relations. Negotiations through intermediaries made little progress, partly because power in Tehran was divided and President Abolhassan Bani-Sadr could not deliver the students.
On 24 April 1980 Carter launched a rescue mission, Operation Eagle Claw. Helicopters and transport planes met at a desert landing site, known as Desert One, in the Tabas region of eastern Iran. Sandstorms and mechanical failures left too few helicopters to continue, and as the force withdrew a helicopter collided with a refuelling aircraft. Eight American servicemen were killed. In Iran the failure was celebrated as divine intervention, and the burnt wreckage was shown on television. Secretary of State Cyrus Vance, who had opposed the mission, resigned.
The Algiers Accords
Several things changed in the second half of 1980. The shah died in Cairo on 27 July. Iraq invaded Iran in September (see the causes of the Iran–Iraq War), and Iran needed its frozen funds and an end to isolation. Algeria acted as mediator. Under the Algiers Accords of 19 January 1981, the United States agreed to release frozen Iranian assets, much of them used to repay Iran’s loans from American banks, to not intervene in Iran’s internal affairs, and to set up an international tribunal in The Hague to settle claims between the two countries. The Iran–United States Claims Tribunal still sits.
The hostages were flown out of Tehran on 20 January 1981, minutes after Ronald Reagan was sworn in as president. Many observers believe the crisis cost Carter re-election in November 1980.

Memory and interpretation
In the Islamic Republic, 4 November (13 Aban) is marked each year as the national day of struggle against “global arrogance”, with rallies outside the former embassy, now a museum run by the Revolutionary Guards. The official view presents the takeover as a defence of the revolution against an American plot. American accounts, such as those of the former hostages and of historian David Farber, treat it as a grave breach of diplomatic immunity, the principle that envoys are protected even in wartime.
Views inside Iran have also shifted. Some of the organisers, including Ebrahim Asgharzadeh and Abbas Abdi, later became reformist politicians; Abdi met the former hostage Barry Rosen in Paris in 1998. The spokeswoman for the students, Masoumeh Ebtekar, became a vice-president under Mohammad Khatami. Ray Takeyh and other historians of US–Iranian relations see the crisis as the moment that fixed hostility between the two states for the following decades. The wider story is told in Iran and the United States, and the struggle at home that ran in parallel in power struggles after the revolution.
