Iranian Hostage Issue: The Iran hostage crisis was a diplomatic standoff between the United States and Iran. Fifty-two American diplomats and citizens were held hostage for 444 days from November 4, 1979, to January 20, 1981, after a group of Iranian college students belonging to the Muslim Student Followers of the Imam’s Line, who supported the Iranian Revolution, took over the U.S. Embassy in Tehran. It stands as the longest hostage crisis in recorded history.
The Algeria Declaration was a set of agreements between the United States and Iran to resolve the Iran hostage crisis, brokered by the Algerian government and signed in Algiers on January 19, 1981. The crisis arose from the takeover of the American embassy in Tehran on November 4, 1979, and the taking hostage of the American staff there. By this accord the 52 American citizens were set free and able to leave Iran.
