Cause

Following the 1979 Iranian Revolution, the Carter administration granted asylum to deposed Shah Mohammad Reza Pahlavi for cancer treatment. Revolutionary student groups, backed by Ayatollah Khomeini, demanded his extradition, viewing American support for the Shah as evidence of US complicity in his regime's human rights abuses. The refusal to extradite him directly precipitated the storming of the US Embassy.

Event

On November 4, 1979, members of the Muslim Student Followers of the Imam's Line seized the US Embassy in Tehran, taking 66 Americans hostage. Fifty-two were held for 444 days as negotiations stalled. A military rescue attempt, Operation Eagle Claw, failed in April 1980, killing eight US soldiers, and six diplomats were separately rescued via the Canadian Caper in January 1980.

Consequence

The crisis ended with the Algiers Accords on January 19, 1981, and hostages were released minutes after Ronald Reagan's inauguration. It was a decisive factor in Carter's landslide 1980 election loss. In Iran, it bolstered Khomeini's authority and hardline theocrats. US-Iran relations deteriorated further through subsequent decades of sanctions tied to Iran's nuclear program and human rights record.
