Tehran

Tehran is the capital and largest city of Iran, situated at the southern foot of the Alborz mountain range in north-central Iran. With a metropolitan population exceeding fifteen million, it is among the largest cities in western Asia. It became the national capital under the Qajar dynasty in 1796 and was the seat of the Pahlavi dynasty from 1925 until the Iranian Revolution of 1979.¹

U.S. Embassy and Hostage Crisis

The American presence in Tehran was extensive under Shah Mohammad Reza Pahlavi, whose government received substantial CIA support since the 1953 CIA-sponsored coup that restored him to power and removed Prime Minister Mohammad Mosaddegh. The U.S. Embassy on Taleghani Avenue was a major intelligence hub managing the CIA's Iran operations.

On November 4, 1979, following Ayatollah Ruhollah Khomeini's return from exile and the Shah's admission to the United States for medical treatment, a group of Iranian students calling themselves the Muslim Student Followers of the Imam's Line seized the Embassy and took 52 American diplomats and staff hostage. Khomeini endorsed the seizure. The 444-day hostage crisis dominated the final year of President Jimmy Carter's administration and is the central event in the October Surprise allegations: the claim that representatives of the Reagan campaign secretly met with Iranian officials - reportedly in Madrid and Paris - to delay the hostages' release until after the November 1980 election. The hostages were released on January 20, 1981, the hour of Reagan's inauguration.²

Iran-Contra Operations

Tehran served as the ultimate recipient end of the covert arms-for-hostages pipeline disclosed in the Iran-Contra Affair. Manucher Ghorbanifar, the Iranian arms broker who served as intermediary between the CIA, Oliver North, David Kimche, and Iranian officials, shuttled between Paris, Tel Aviv, and Tehran coordinating the transactions. Arms deliveries included TOW anti-tank missiles and HAWK surface-to-air missiles. Iranian factions associated with Hashemi Rafsanjani were the principal interlocutors on the Iranian side.¹

Intelligence Significance

The CIA's Tehran station was among the agency's most significant Cold War posts, running extensive operations against Soviet targets in neighboring Soviet republics. The station's files and network were exposed when the Embassy was seized; the documents were painstakingly reassembled from shredded material and published by the Iranian government in the multi-volume Documents from the U.S. Espionage Den series, providing unusual transparency into CIA operations methodology.²

Shapour Bakhtiar, the Shah's final prime minister, was assassinated in Paris in August 1991 by Iranian intelligence agents - one of multiple overseas assassinations carried out by the Islamic Republic against opposition figures during the 1980s and 1990s.
