Operation Ajax The 1953 coup in Iran was a covert action that removed Prime Minister Mohammad Mossadegh and strengthened Shah Mohammad Reza Pahlavi. It involved the Central Intelligence Agency and the British Secret Intelligence Service supporting royalists, street demonstrations, and military interventions to reverse the oil nationalization. The event reshaped Middle East politics, Anglo-American relations, and Cold War alignments.

Background

By the early 1950s, tensions between Iran and the United Kingdom centered on the Anglo-Iranian Oil Company and the 1901 and 1933 concessions. Nationalist politics led by Mohammad Mossadegh and the National Front sought control of oil revenues, prompting disputes with United Kingdom. The Cold War context, involving the United States and Soviet Union, raised fears in Washington, D.C. about communist influence linked to the Tudeh Party. Domestic actors included the ulama, bazaaris, military, and aristocratic elites around the Pahlavi dynasty. Previous crises—such as the 1941 Anglo-Soviet invasion of Iran and the Iran crisis of 1946—framed foreign perceptions of Iranian stability.

Planning and UK–US Collaboration

After failed negotiations between Britain and Iran over oil, British Secret Intelligence Service drafted contingency plans. The Foreign Office and Prime Minister Winston Churchill authorized initiatives aimed at undermining Mohammad Mossadegh's coalition. Central Intelligence Agency planners in Washington, D.C. coordinated with Office of Policy Coordination elements and Joint Chiefs of Staff observers. Key figures included Kermit Roosevelt Jr. for the Central Intelligence Agency and Norman Darbyshire of the Secret Intelligence Service. Operation plans relied on influencing the Iranian military, mobilizing religious leaders, funding political groups, and orchestrating demonstrations in Tehran. Legal and diplomatic cover involved the United States Department of State and the United Kingdom Foreign Office.

Coup Execution (1953)

The coup unfolded in two main phases: an initial failed attempt and a subsequent successful operation. The first phase saw Mohammad Mossadegh use emergency powers and the Iranian Parliament's actions against royalist plots; initial coup efforts were foiled, leading to a brief exile of the Shah to Italy and Egypt. The second phase featured coordinated street clashes, bribed Iranian military officers, manipulated press outlets including pro-Shah newspapers, and public declarations by religious figures sympathetic to the royalists. Key scenes occurred around the Majlis, Telegraph Square (Arg) in Tehran, and military barracks where units loyal to the Shah, led by officers such as General Fazlollah Zahedi, moved to arrest Mohammad Mossadegh. The operation culminated in Mossadegh's arrest and transfer to Savak-era detention facilities controlled by pro-Shah authorities.

Shah's Consolidation and Immediate Aftermath

Following Mossadegh's removal, Mohammad Reza Pahlavi consolidated power through appointments, military purges, and reinstating monarchical authority with figures like General Fazlollah Zahedi as prime minister. The parliament endorsed actions against nationalists, while the ulama and bazaaris were courted to legitimize the new order. The Anglo-Iranian Oil Company eventually restructured into new arrangements involving Western oil interests and consortium agreements. Security services were expanded, contributing to later institutions such as SAVAK and closer ties with Washington on intelligence and military aid.

Domestic and International Reactions

Domestically, reactions ranged from royalist celebration to nationalist and leftist outrage; the Tudeh Party and remnants of the National Front faced repression. Internationally, Britain initially claimed credit for protecting its oil interests, while United States officials publicly denied direct involvement even as diplomatic cables and later declassified documents revealed active participation. The coup influenced relations with neighboring states, affecting discussions in forums like the United Nations and shaping perceptions in capitals including Moscow, Paris, and Washington, D.C..

Historical Assessments and Legacy

Scholars debate motives and consequences, citing archival evidence from the United Kingdom National Archives and United States National Archives showing collaboration between British Secret Intelligence Service and Central Intelligence Agency. Critics argue the coup undermined Iranian democracy, accelerated the rise of authoritarian policing, and seeded long-term anti-Western sentiment culminating in events such as the Iranian Revolution of 1979. Defenders contend Cold War imperatives and protection of Western energy interests required intervention. The episode features in studies by historians of Cold War, Middle East, intelligence history, and political development, influencing analyses of U.S. foreign policy, British foreign policy, and revolutionary movements across the Global South.
