SAVAK
The Shah's feared secret police, whose surveillance and torture became shorthand for Pahlavi repression and helped ignite the revolution that destroyed it.

For twenty-two years, the most frightening word in Iran was an acronym. SAVAK, from the Persian for Organization of National Intelligence and Security, was the Shah's secret police, and by the 1970s ordinary Iranians assumed it was listening: to the phone call, the classroom, the cafe conversation. Its job was to keep Mohammad Reza Shah on his throne by finding his enemies before they found each other. Its method was fear. In the end the fear it manufactured helped destroy the man it was built to protect.
Built with help
SAVAK was founded in 1957, in the aftermath of the 1953 coup, with training and organizational models supplied by the American CIA and, later, Israel's Mossad; French intelligence lent a hand too. Its first targets were the communist Tudeh Party and other leftists, then, increasingly, the religious opposition inspired by Khomeini. It ran a vast web of informers, censored the press and the universities, vetted government appointments, and maintained interrogation centers where torture was routine: floggings, electric shock, sleep deprivation, and worse. Prisons like Evin, opened in 1972, became bywords for what happened to those who spoke. Estimates of its size vary wildly, from a few thousand full-time officers to a shadow network of part-time informers reaching into every ministry, factory, and campus, and much of its power came from Iranians never quite knowing which of their neighbors belonged to it.
The cost of fear
Repression bought quiet, not loyalty. By closing every legal channel of dissent, SAVAK ensured that opposition could survive only underground or inside the mosque, the one institution it could not fully penetrate. That helped guarantee the mosque would inherit the revolution. Through the 1970s, as Amnesty International and Western reporters publicized its methods, and the group warned in the mid-1970s that few countries had a worse record on torture, SAVAK became an embarrassment to a Shah who wanted to be seen as a modernizer, and a rallying cry at home. The SAVAK interrogator became a stock villain of revolutionary posters and Friday sermons. Every prisoner it killed created martyrs and mourners; the traditional 40-day Shia mourning cycles turned funerals into protests, and protests into the rhythm of the revolution.
Replaced, not abolished
When the monarchy fell in early 1979, revolutionaries hunted down SAVAK officers, and its long-serving director, Nematollah Nassiri, was executed. The organization was formally dissolved. But the Islamic Republic did not govern without a secret police. It built its own, eventually the Ministry of Intelligence, and critics later charged that the new organs used many of the same tools, sometimes the same cells, against a new set of dissidents. SAVAK's deepest lesson was not about one dynasty's cruelty. It was that a state which can rule only through fear has already begun to lose, and that the machinery of terror rarely dies with the regime that built it.
