"The United States, along with the UK, played a significant role in installing Shah Mohammad Reza Pahlavi as the ruler of Iran in 1953. This was achieved through a US-led coup d'état that overthrew the democratically elected Prime Minister Mohammad Mosaddegh. The coup, code-named Operation Ajax, was driven by Western fears of Soviet influence in Iran, particularly due to Iran's strategic location and oil wealth."
