Short Answer
In the sweltering heat of Tehran in mid-August 1953, the capital of Iran was a city of rumors and contradictions. For months, the government of Prime Minister Mohammad Mosadeq had been locked in a tense struggle with the young Shah, Mohammad Reza Pahlavi, over oil nationalization and the limits of royal power. On the morning of August 16, the Shah issued a royal decree dismissing Mosadeq and appointing General Fazlollah Zahedi as Prime Minister—a move that would trigger a chaotic chain of events. The U.S. Embassy in Tehran reported the city calm but with tanks and security forces deployed, and rumors of a coup flew through the streets. By August 19, the coup had succeeded, but not without confusion, violence, and a dramatic reversal of fortunes. This article reconstructs those days as they were recorded by contemporary observers: diplomatic cables, newspaper headlines, and the anxious words of officials on the ground.
What Happened?
The immediate origins of the coup can be traced to a royal decree issued on August 16, 1953. According to a U.S. Embassy telegram dated August 16 at 10 a.m., the Shah had dismissed Mosadeq and appointed General Zahedi as Prime Minister. The same report noted that the Acting Minister of Court, Amini, and other court officials had been arrested that morning. The city was reported calm, but tanks and truckloads of security forces were deployed around royal palaces and the Prime Minister’s residence. An orderly crowd of approximately 200 people was seen marching toward Baharestan Square waving Iranian flags. The Prime Minister’s office advised the U.S. Embassy and Point IV personnel to close early because trouble was expected.
However, the coup initially failed. The Tudeh Party’s newspaper, Shojat, later claimed that Mosadeq had been tipped off to the plot and had taken countermeasures. By August 19, the situation had reversed. A second telegram from the Embassy on August 19 reported that the Press and Propaganda offices had been occupied, and telegrams were being sent to the provinces urging pro-Shah action similar to that in Tehran. The telegram described truckloads of soldiers, civilians, and six tanks roaming the city displaying pictures of the Shah. Radio Tehran played only recorded music for a short period after the offices were taken and then fell silent. General Daftari was appointed Tehran Military Governor and Police Chief, apparently attempting to use the Customs Guards organization he previously commanded on behalf of the Mosadeq regime. The U.S. Ambassador, Loy Henderson, was the author of the telegram.
How It Was Seen at the Time
Contemporaries were deeply confused about what was happening. The U.S. Embassy telegram of August 16 noted that rumors were prevalent that the coup had been inspired by the government itself. The reasoning was that the action would give Mosadeq an excuse to move against the Shah. The telegram noted that the only paper to report the alleged coup was the Communist-aligned Shoojat, which had predicted a coup since August 13. The paper claimed that Mosadeq was tipped off on Friday afternoon and that the plotters had sent a white flare to delay action. This atmosphere of suspicion and counter-rumor was typical of the period. The New York Times headline from August 17, 1953, read simply “UPHEAVAL IN IRAN,” describing a “confused and so far bloodless revolt” in which the rival moves were still unclear. The prevailing mood was one of uncertainty, with officials and ordinary Iranians alike unsure who was in control.

Contemporary Newspaper Coverage
The New York Times reported the coup in its August 17, 1953 issue, under the headline “UPHEAVAL IN IRAN.” The article described the revolt as “confused and so far bloodless,” with the rival moves still unclear. This reflects the fog of events at the time. The Times article was based on wire reports and official statements, not yet on the full picture. The Tudeh newspaper Shoojat was the only paper to have a detailed account of the coup attempt, and it had been predicting a coup since August 13. According to the U.S. Embassy telegram of August 16, the Shoojat reported that Mosadeq was tipped off to the plot and that the coup was to have occurred on the night of August 15. The paper also claimed that the coup plotters had sent a white flare to delay action. These reports were not widely believed at the time, but they later proved to be more accurate than many thought.
Official Reports
The most authoritative contemporary official reports are the U.S. Embassy telegrams to the Department of State. The telegram of August 16 (10 a.m.) provided a detailed account of the Shah’s decree, the arrest of court officials, and the military presence in Tehran. It also noted the rumor that the coup was government-inspired. The telegram of August 19 described the successful coup: the occupation of the Press and Propaganda offices, the movement of pro-Shah soldiers and tanks, and the appointment of General Daftari as Military Governor. These reports are crucial because they show the pace of events and the uncertainty of the moment. They also reveal the U.S. government’s close monitoring of the situation, though they do not disclose any U.S. involvement in the coup.
What People Feared
In the immediate aftermath of the coup attempt, many feared the situation could escalate into civil war or that the Tudeh Party, Iran’s Communist faction, might seize power. The U.S. Embassy’s report of August 16 noted that the government had ordered the Embassy and Point IV to close because trouble was expected, indicating a fear of violent unrest. The Tudeh newspaper’s predictions of a coup, and its later claims of a government plot, fueled anxiety that the coup would be used as a pretext to crush opposition. There were also fears of foreign intervention, although the public did not know about the CIA’s role. The New York Times described the revolt as “bloodless” so far, but the potential for violence was a constant worry.
What People Expected Would Happen Next
Immediately after the coup, many observers expected the situation to remain fluid. The U.S. Embassy’s August 19 telegram reported that the coup was still in progress, with pro-Shah forces moving through the city and the press offices occupied. The appointment of General Daftari as Military Governor suggested that the Mosadeq government was trying to retain control, but the occupation of the Press and Propaganda offices indicated a shift. The New York Times on August 17 had noted that the rival moves were still unclear, suggesting that observers expected further upheaval. The eventual outcome—the fall of Mosadeq and the establishment of a pro-Shah government under Zahedi—was not clear to contemporaries at the time, but the rapid movement of troops and the support for the Shah indicated a decisive turn.
Aftermath
Within days, the coup succeeded. By the end of August, Mosadeq was arrested, and the Shah returned from his trip to the Caspian region. General Zahedi was installed as Prime Minister, and the oil industry was eventually re-nationalized under a new agreement with Western powers. The coup marked a decisive turning point in Iranian history, leading to the consolidation of the Shah’s autocratic rule and the deepening of U.S.–Iranian relations. The immediate aftermath was marked by the suppression of the Tudeh Party and other opposition groups, as well as a period of political instability. The U.S. Embassy’s reports reflect the rapid consolidation of the new government, though the long-term consequences were not yet apparent.
How Historians See It Today
At the time, the coup was seen as a political crisis that was resolved in favor of the Shah. Many contemporaries, including the U.S. Embassy, reported the events as a natural power struggle between the Shah and his Prime Minister. The role of the United States and Britain was not publicly acknowledged. Modern historians, however, have established that the coup was orchestrated by the CIA and MI6 under the code name Operation Ajax, with the goal of protecting Western oil interests and containing Soviet influence. The declassified documents and memoirs of key participants, such as CIA officer Kermit Roosevelt, have revealed a coordinated effort to support the Shah and to remove Mosadeq. This has shifted the interpretation from a domestic conflict to a significant act of foreign intervention, with lasting consequences for Iran’s political development and its relationship with the West.
The primary sources from the period—the U.S. Embassy telegrams, the New York Times articles, and the reports of the Tudeh press—offer a unique window into the confusion and fear of the moment. They remind us that historical events are often experienced as a series of contradictory rumors and incomplete information, even as the long-term outcome appears inevitable. The 1953 coup was not simply a footnote in history; it was a day when the future of Iran was uncertain, and the people of Tehran lived through that uncertainty in real time.
