Mohammad Reza Pahlavi (26 October 1919 – 27 July 1980) was the last Shah of Iran, reigning from 1941 to 1979 as the second monarch of the Pahlavi dynasty. He succeeded his father, Reza Shah, and ruled the Imperial State of Iran until his overthrow in the Islamic Revolution, which abolished the nearly 2,500-year-old Iranian monarchy. During his reign, he assumed the title (),D. N. MacKenzie. A Concise Pahlavi Dictionary. Routledge Curzon, 2005. and held several other titles, including () and ().
Born in Tehran, Pahlavi was named crown prince upon his father's coronation in 1926, and later served in the Iranian Army. The Anglo-Soviet invasion of Iran in 1941 forced Reza Shah's abdication and Mohammad Reza's succession. His early reign was marked by political instability, including the Iran crisis of 1946 and a turbulent struggle for power with prime minister Mohammad Mosaddegh, who nationalized the British-owned oil industry with popular support. However, Iran's oil exports subsequently fell sharply, and Mosaddegh's popularity declined amid mounting economic difficulties. After enacting measures to expand his political power, Mosaddegh was overthrown in the 1953 Iranian coup d'état, carried out by pro-monarchy forces with British and American involvement. Subsequently, the Shah's authority increased, and his political opposition was increasingly suppressed.
In 1963, the Shah introduced the White Revolution, a broad program of economic and social modernization accompanied by heavy investment in infrastructure and domestic industry. Iran subsequently became one of the largest and fastest-growing economies in the world, with real GDP per capita nearly tripling between 1963 and 1976. Supported by the United States, the Shah pursued an extensive arms buildup, establishing Iran as the preeminent military power in the Persian Gulf. In 1973, he concluded the Sale and Purchase Agreement, which effectively nationalized Iran's oil operations. Rising oil revenues throughout the decade accelerated development and improved living standards, but also strained Iran's absorptive capacity, contributing to inflation, shortages, and persistent economic inequality.
Mounting socioeconomic problems and increased political repression soon contributed to growing dissatisfaction with the Shah's rule. In January 1978, a newspaper article attacking opposition cleric Ruhollah Khomeini sparked protests that rapidly developed into widespread demonstrations. The crisis intensified with the Cinema Rex fire and the Jaleh Square massacre, along with nationwide strikes beginning in October, leaving the Shah's position increasingly untenable. On 16 January 1979, the Shah left Iran for exile, transferring his duties to a regency council. Within a month, the Imperial State collapsed, and Khomeini emerged as the supreme leader of the new Islamic Republic. After difficulties obtaining asylum in various countries due to the Iran hostage crisis, Pahlavi died in exile on 27 July 1980 in Egypt, where he had been welcomed by President Anwar Sadat.
Pahlavi has been widely characterized as a pro-western dictator by international observers. His legacy is highly divisive, as his government has been accused of widespread human rights violations, including the frequent use of torture. Although the benefits of economic growth were unevenly distributed, Pahlavi remains credited with the modernization of the Iranian economy in the late 20th century, and with establishing Iran as a prominent international power. Positive views of his reign have persisted among segments of the Iranian population and diaspora, becoming particularly visible during the 2025–2026 Iranian protests through pro-Pahlavi and monarchist slogans.
Early life, family and education Mohammad Reza was born on 26 October 1919 in Tehran to Reza Khan (later Reza Shah Pahlavi), a brigadier general of the Persian Cossack Brigade, and his second wife, Tadj ol-Molouk. His father was of Mazandarani origin and was born in Alasht, Mazandaran province. His paternal grandmother was a Muslim immigrant from Georgia (then part of the Russian Empire), whose family had emigrated to Iran following the Russo-Persian Wars in the nineteenth century. Tadj ol-Molouk was born in Baku, Russian Empire (present-day Azerbaijan), and was the daughter of Teymūr Khan Ayromlou, an army general of Ayrum descent.
Mohammad Reza was Reza Khan's eldest son and the third of his eleven children by four women. He was born with his twin sister, Ashraf; his other full siblings were his older sister Shams and younger brother Ali Reza. Reza Khan reportedly regarded his first son's birth as a good omen and called him khoshghadam ("bird of good omen").Fereydoun Hoveyda. The Shah and the Ayatollah: Iranian Mythology and Islamic Revolution (Westport: Praeger, 2003) p. 5; and Ali Dashti, Panjah va Panj ("Fifty Five") (Los Angeles: Dehkhoda, 1381) p. 13. Following the enactment of Iran's surname law, Reza Khan adopted the surname Pahlavi, derived from Middle Persian. On 24 April 1926, the day before his father's coronation, six-year-old Mohammad Reza was proclaimed Crown Prince of the newly established Pahlavi dynasty.
Growing up, Mohammad Reza was very close to his twin sister Ashraf, who described her brother as the "centre of my existence."Zonis, Marvin. Majestic Failure: The Fall of the Shah, University of Chicago Press, 1991, p. 33. He also shared a close relationship with his mother, Tadj ol-Molouk, and his older sister Shams. Tadj ol-Molouk was assertive and deeply superstitious, encouraging her son's belief that he was destined for an important future. Upon becoming Crown Prince, however, he was separated from his mother and sisters and was placed under the educational supervision of military officers.Zonis, Marvin. Majestic Failure: The Fall of the Shah, University of Chicago Press, 1991, p. 54. Reza Shah further ordered that everyone, including his mother and siblings, address the Crown Prince as "Your Highness".
Mohammad Reza had a difficult relationship with his father, whom he later described in his autobiography Mission for My Country as "one of the most frightening men" he had known. According to historian Abbas Milani, Reza Shah was an authoritarian and emotionally distant father, and Mohammad Reza grew up fearful of him and lacking self-confidence. Their relationship remained highly formal; Reza Shah addressed his son as shoma ("sir") rather than the informal tow ("you"), and expected the same formality in return.
Education In 1931, at the recommendation of Minister of Court Abdolhossein Teymourtash, Reza Shah sent the Crown Prince to Institut Le Rosey, a private boarding school in Switzerland. He left Iran on 7 September 1931 and became the first Iranian heir apparent to be sent abroad for his education. His adjustment to life in Switzerland was initially difficult. Accustomed to the deference afforded to him in Iran, he reportedly demanded that fellow students stand at attention in his presence, but soon adapted to the comparatively egalitarian environment of the school. As a student, Mohammad Reza played competitive football. In addition to his native Persian, Mohammad Reza spoke English, French, and German fluently. He developed a lasting interest in French language and culture; writing for the school newspaper in French in 1935 and 1936, he credited Le Rosey with broadening his outlook and introducing him to European civilization. He also befriended Ernest Perron, a teacher who introduced him to French literature and became one of his closest confidants. When Mohammad Reza returned to Iran in 1936, Perron accompanied him and subsequently remained associated with the royal court at the Marble Palace.Zonis, Marvin. Majestic Failure: The Fall of the Shah, University of Chicago Press, 1991, p. 116 f.
After returning to Iran, Mohammad Reza completed his secondary education and enrolled at the Madrasa Nezam, a military academy in Tehran. He graduated as a second lieutenant in 1938 and was subsequently promoted to captain, a rank he held until his accession to the throne. From 1938 to 1941, he served as an army inspector, travelling throughout Iran to examine both civil and military installations. Rise to power and rule as Shah First marriage
One of the main initiatives of Iranian and Turkish foreign policy had been the Saadabad Pact of 1937, an alliance bringing together Turkey, Iran, Iraq, and Afghanistan, with the intent of creating a Muslim bloc that, it was hoped, would deter any aggressors. President Mustafa Kemal Atatürk of Turkey suggested to his friend Reza Khan during the latter's visit that a marriage between the Iranian and Egyptian courts would be beneficial for the two countries and their dynasties, as it might lead to Egypt joining the Saadabad pact.. Dilawar Princess Fawzia of Egypt (5 November 1921 – 2 July 2013) was daughter of King Fuad I of Egypt and Nazli Sabri, and sister of King Farouk I of Egypt. In line with Atatürk's suggestion, Mohammad Reza and the Egyptian Princess Fawzia were married on 15 March 1939 in the Abdeen Palace in Cairo. Reza Shah did not participate in the ceremony. During his visit to Egypt, Mohammad Reza was greatly impressed with the grandeur of the Egyptian court as he visited the various palaces built by Isma'il "the Magnificent" Pasha, the famously free-spending khedive of Egypt, and resolved that Iran needed similarly grandiose palaces to match them.
Mohammad Reza's marriage to Fawzia produced one child, Princess Shahnaz Pahlavi (born 27 October 1940). Their marriage was not a happy one, as the Crown Prince was openly unfaithful, often being seen driving around Tehran in one of his expensive cars with one of his girlfriends. Additionally, Mohammad Reza's dominating and possessive mother saw her daughter-in-law as a rival to her son's love, and took to humiliating Princess Fawzia, whose husband sided with his mother. A quiet, shy woman, Fawzia described her marriage as miserable, feeling very much unwanted and unloved by the Pahlavi family and longing to return to Egypt. In his 1961 book Mission for My Country, Mohammad Reza wrote that the "only happy light moment" of his entire marriage to Fawzia was the birth of his daughter.
Anglo-Soviet invasion and deposition of his father Reza Shah
Meanwhile, in the midst of World War II in 1941, Nazi Germany began Operation Barbarossa and invaded the Soviet Union, breaking the Molotov–Ribbentrop Pact. This had a major impact on Iran, which had declared neutrality in the conflict. In the summer of 1941, Soviet and British diplomats passed on numerous messages warning that they regarded the presence of Germans administering the Iranian state railroads as a threat, implying war if the Germans were not dismissed. Britain wished to ship arms to the Soviet Union via Iranian railroads, and statements from the German managers of the Iranian railroads that they would not cooperate made both the Soviets and British insistent that the Germans Reza Khan had hired be sacked at once. As his father's closest advisor, the Crown Prince Mohammad Reza did not see fit to raise the issue of a possible Anglo-Soviet invasion of Iran, blithely assuring his father that nothing would happen. The Iranian-American historian Abbas Milani wrote about the relationship between the Reza Khan and the Crown Prince at the time, noting, "As his father's now constant companion, the two men consulted on virtually every decision".
