The 1953 Iranian Coup: How the CIA Overthrew a Democracy for Oil

On the morning of August 19, 1953, Mohammad Mosaddegh — the democratically elected Prime Minister of Iran, Time magazine’s Man of the Year, and one of the most popular leaders in the country’s modern history — was overthrown by a mob that had been paid, organized, and set loose by the CIA and British intelligence. Within hours, tanks loyal to Shah Mohammad Reza Pahlavi had seized Tehran’s key installations. Mosaddegh was arrested in his pajamas. The coup was over before sunset.

The operation had a name: AJAX in Washington, Boot in London. Its architects had a goal: remove a leader who had dared to nationalize Iran’s oil industry and return control of that oil to a Western-friendly monarch who would keep it flowing to Anglo-American corporations. What they set in motion that August day — the destruction of Iranian democracy, the installation of a repressive autocracy, and the accumulation of grievances that would eventually explode in the 1979 Islamic Revolution — is still reshaping the world today.

The Man They Had to Remove

Mohammad Mosaddegh was, by almost any measure, an extraordinary figure. Born into the Iranian aristocracy, educated in Paris and Switzerland, he had spent decades fighting for Iranian constitutionalism and parliamentary governance. By the time he became Prime Minister in April 1951, he was a symbol of something genuinely threatening to Western interests: a non-communist, democratically legitimate nationalist who intended to make his country’s resources serve his country’s people.

The flashpoint was oil. The Anglo-Iranian Oil Company (AIOC) — the forerunner of today’s BP — had operated in Iran since 1913 under terms that were, by any objective assessment, spectacularly lopsided. The AIOC took the lion’s share of profits while Iran received a fraction of the revenues generated by its own subsoil resources. The company paid more in taxes to the British government than it paid in royalties to Iran. Its refinery at Abadan was the largest in the world, and the city that grew up around it was segregated: British employees lived in bungalows with gardens while Iranian workers crowded into shantytowns.

When Mosaddegh’s government nationalized the AIOC in May 1951, the Iranian parliament voted unanimously. The move was wildly popular at home — and immediately produced a crisis with Britain, which imposed a crippling embargo on Iranian oil and began lobbying its American allies to help remove Mosaddegh from power.

The British Case and the American Hesitation

The British were the first to approach the CIA with a plan for regime change. The MI6 pitch framed the problem in terms that resonated powerfully in Washington: Mosaddegh’s weakness, they argued, would create a vacuum that the Iranian Tudeh Party (communist) could exploit. Iran might fall into the Soviet orbit. The oilfields of the Persian Gulf could come under hostile control.

The Truman administration was skeptical. Secretary of State Dean Acheson recognized the colonial dimensions of the British complaint and had little enthusiasm for helping London recover what was essentially an imperial asset. Truman himself was ambivalent. The coup plan stalled.

Then Eisenhower took office in January 1953, and the calculus changed. The new administration was more receptive to covert action as a foreign policy tool, and the Cold War framing — Mosaddegh as unwitting enabler of communist takeover — found fertile ground with Secretary of State John Foster Dulles and his brother, CIA Director Allen Dulles. By June 1953, Operation AJAX had been approved.

How You Buy a Coup

The operational blueprint, later documented in a CIA history that was partially declassified in 2013, was a masterclass in covert political manipulation. Kermit Roosevelt Jr. — grandson of President Theodore Roosevelt — was the CIA’s man on the ground. His job was to assemble the components of a manufactured crisis that would force the Shah to dismiss Mosaddegh and install a pro-Western successor.

The ingredients included:

  • Bribed politicians and clerics: CIA funds flowed to Iranian parliamentarians, newspaper editors, and religious figures who were willing to denounce Mosaddegh. Fabricated stories circulated about his communist sympathies and threats to Islam.
  • Paid street mobs: Roosevelt worked with Iranian military officers and Tehran underworld figures to organize demonstrations. Thugs were paid to pose as Mosaddegh supporters and commit acts of violence — attacking clerics, vandalizing mosques — to discredit the government.
  • Military co-option: Key Iranian military officers were identified, bribed, and organized into a network that would move on a signal from Washington and London.
  • The Shah’s reluctant cooperation: Mohammad Reza Shah was, at this point, a nervous and somewhat spineless monarch. He had to be pressured repeatedly to sign the dismissal decrees. He fled to Rome when the first coup attempt on August 15-16 failed. Only when Roosevelt convinced him that American support was firm did he agree to return.

The second and successful attempt came on August 19. Roosevelt’s paid mobs marched from the Tehran bazaars, joined by military units. Mosaddegh’s supporters were outmaneuvered and overwhelmed. By evening, the Prime Minister had surrendered. He would spend the rest of his life under house arrest.

The Confession That Took Sixty Years

For decades, the US government officially denied any role in the coup. The CIA maintained its silence even as academics, journalists, and foreign governments documented the operation in increasing detail. The definitive admission came in 2013, when the National Security Archive published a declassified CIA history that stated plainly: “The coup was carried out under CIA direction as an act of U.S. foreign policy, conceived and approved at the highest levels of government.”

The document, written in 1954 by CIA historian Donald Wilber — one of the operation’s architects — described the mechanics of the coup in clinical detail. It confirmed the payments to politicians, the manufactured propaganda, the organized mobs, and the coordination with British intelligence.

Secretary of State Madeleine Albright had offered a partial acknowledgment in 2000, calling the coup “a setback for Iran’s political development.” President Barack Obama mentioned it briefly in his 2009 Cairo speech. But the full documentary confession came only when the NSA published the CIA’s own history.

The Shah’s Iran: What America Bought

The Shah that American and British intelligence restored to power in 1953 was not a benevolent modernizer. He was an autocrat who, with American support and CIA training assistance, built one of the most feared secret police agencies of the twentieth century: SAVAK.

Established in 1957 with direct CIA and Mossad involvement, SAVAK surveilled, arrested, tortured, and killed the Shah’s political opponents. Estimates of political prisoners under the Shah range from tens of thousands to higher figures. Amnesty International described Iran in the 1970s as having the worst human rights record in the world. The torture techniques documented by human rights organizations — many of them bearing a disturbing resemblance to methods taught at American-run training programs — became a symbol of everything the Islamic Revolution would claim to oppose.

The oil, meanwhile, flowed on terms that were somewhat less favorable to Western companies than before — a new consortium arrangement divided the spoils among American, British, French, and Dutch corporations — but the principle of Iranian state ownership over its own resources, the thing Mosaddegh had fought for, was effectively nullified for another quarter century.

The Blowback: 1979 and Everything After

In January 1979, the Shah fled Iran for the last time. The Islamic Revolution, led by Ayatollah Ruhollah Khomeini, swept away the monarchy in a wave of popular fury that had been building for twenty-five years. Among the revolution’s central grievances was the 1953 coup — the original sin of American interference in Iranian affairs that had installed and sustained the hated Shah.

When Iranian students seized the American Embassy in Tehran in November 1979 and held 52 American diplomats for 444 days, they justified the action partly as retaliation for America’s role in 1953. The CIA documents they found in the embassy — and painstakingly reassembled after being shredded — confirmed what Iranians had always suspected about American intelligence operations on their soil.

The hostage crisis poisoned US-Iran relations for decades. The Reagan administration’s support for Saddam Hussein during the Iran-Iraq War (1980-1988), the nuclear standoff of the 2000s-2010s, the cycles of sanctions and confrontation — all of it traces a line back to August 19, 1953, and the decision to overthrow a democracy for oil.

A Thought-Provoking Conclusion

The 1953 Iranian coup is often cited by scholars of US foreign policy as the clearest example of “blowback” — the CIA term for the unintended consequences of covert operations. The word was coined, appropriately, by the authors of the AJAX post-mortem. The operation achieved its immediate objectives: Mosaddegh was gone, the oil flowed, the Shah was in place. But the costs accumulated silently over twenty-five years and then detonated with revolutionary force.

What would Iran look like today if Mosaddegh had been allowed to govern? It’s a counterfactual that haunts historians. A democratic, oil-sovereign, non-aligned Iran at the heart of the Middle East — the road not taken. Instead, America and Britain chose a friendly dictator, and a generation later, they got a hostile theocracy.

The lesson seems obvious in retrospect. And yet the pattern — covert intervention, installed autocrat, accumulating grievances, eventual explosion — would repeat itself in country after country across the decades that followed.
