How did the 1953 coup in Iran influence later opposition to Mohammad Reza Shah Pahlavi?

The 1953 coup, which removed the democratically elected Prime Minister Mohammad Mosaddegh and restored Mohammad Reza Shah Pahlavi to power, is widely considered to have sown the seeds for the Iranian Revolution of 1979.1

The coup influenced later opposition to the Shah in several critical ways:

• Amplified Autocracy: With his position strengthened by foreign support from the United States and the United Kingdom, the Shah’s rule became increasingly autocratic. This centralization of power left minimal outlets for political participation, marginalizing opposition groups.23
• Perception of Foreign Subservience: The Shah’s return to power via a foreign-orchestrated coup fueled long-standing resentment regarding his perceived subservience to Western powers. This narrative was central to the rhetoric of opposition leaders like Ruhollah Khomeini, who accused the regime of being a puppet of foreign interests.3
• Heightened Repression: The regime’s reliance on the SAVAK (secret police) to suppress dissent and opposition became a defining feature of the post-1953 era, fostering deep-seated public dissatisfaction.23

Ultimately, these factors created a broad coalition of opposition—including clergy, intellectuals, and merchants—that united to overthrow the Pahlavi monarchy.3
