Mohammad Mosaddegh, the prime minister who nationalised the Iranian oil industry in 1951, initiated sweeping social reforms that included unemployment compensation and the abolition of forced peasant labour. His political trajectory spanned the transition from the Qajar dynasty to the Pahlavi state, eventually ending in his overthrow during the 1953 Iranian coup d'état.
Academic Foundation and Early Career
Born in Tehran in 1882, Mosaddegh belonged to an influential family connected to the Qajar court. He pursued extensive studies in Europe, attending Sciences Po and the University of Paris. In 1913, he completed a doctorate in law at the University of Neuchâtel, becoming the first Iranian to earn a PhD from a European university. Upon his return to Iran, he taught at the Tehran School of Political Science before engaging in a parliamentary career that began during the Constitutional Revolution.

Throughout the early 1920s, Mosaddegh held several government positions, including Minister of Economic Affairs and Finance, and Foreign Affairs Minister. He served as the governor of Fars and Azerbaijan provinces. In 1925, he expressed public opposition to the transition from the Qajar monarchy to the Pahlavi dynasty, arguing that the ascent of Reza Shah violated the 1906 Iranian constitution. Following this shift in power, he withdrew from political life for a period.
The Abadan Crisis and Prime Ministership
Elected prime minister in 1951, Mosaddegh focused on asserting national control over Iranian resources. His administration initiated the nationalisation of the Anglo-Iranian Oil Company, triggering the Abadan Crisis and a direct confrontation with British interests. While in office, he introduced progressive social measures, including land reforms and mandated sickness benefits for workers. His tenure concluded in 1953 following a coup d'état supported by the United Kingdom and the United States.
Suppression and Final Years
Following the consolidation of power by Mohammad Reza Pahlavi in 1954, Mosaddegh’s National Front was suppressed. He faced a trial for treason, resulting in a three-year imprisonment. Following his release, he remained under house arrest in Ahmadabad-e Mosaddeq until his death in 1967. He was buried within his home to mitigate the risk of public political demonstrations.
