Pahlavi dynasty

• 1. Introduction

  ›

  The Pahlavi dynasty was born in a village called Alasht in 1878, when a child named Reza Khan entered a world that could not have predicted he would one day rule Iran. He was the son of a Mazandarani soldier who had served in the 7th Savadkuh Regiment, and his mother was a Georgian Muslim immigrant whose family had fled to Iran after the Russo-Persian Wars stripped the Caucasus from the Qajar empire. From that obscure corner of Mazandaran Province, Reza Khan would rise through the military ranks, seize control of a country, rename himself, and found a dynasty that would last fifty-three years. How did a non-aristocratic soldier with no royal blood come to sit on the Peacock Throne? And how did a dynasty so deliberately modern, so rooted in pre-Islamic Persian identity, fall so completely in a single revolution?

  On the 14th of January 1921, a forty-two-year-old soldier named Reza Khan was promoted by British General Edmund Ironside to lead the Persian Cossack Brigade. That promotion, engineered by the British, set the dynasty's founding moment in motion. Within roughly a month, Reza Khan marched a detachment of three thousand to four thousand Cossack troops toward Tehran under British direction. The capital fell, and by 1923 the rest of the country had followed. The old Qajar dynasty did not go quietly; it had to be formally dismantled. In October 1925, the Majlis voted to depose Ahmad Shah Qajar and send him into exile. Then, on the 12th of December 1925, that same parliament declared Reza Pahlavi the Shah of Iran, acting under the authority of the Persian Constitution of 1906. Reza had briefly considered turning Iran into a republic, inspired by what Mustafa Kemal Ataturk had done in neighboring Turkey. Clerical opposition and British pressure killed the idea, and a monarchy was declared instead.

• 3. A Name Drawn from the Ancient World

  Reza Khan did not simply take power; he took a new identity to go with it. The name Pahlavi was not a family name passed down through generations. It was chosen deliberately from the Pahlavi scripts of the Middle Persian language, the writing system of the Sasanian Empire that ruled Iran in the pre-Islamic era. By selecting that name, Reza Shah announced exactly what kind of monarchy he intended to build. The dynasty would root its legitimacy not in Islam or in the Qajar lineage it replaced, but in the deep pre-Islamic past, especially in the heritage of the Achaemenid Empire. This nationalist vision grew more pronounced under the dynasty's second and final Shah, Mohammad Reza Pahlavi, who reigned from 1941 until he was deposed on the 11th of February 1979. The dynasty's lifespan stretched fifty-three years from that first declaration in December 1925 to its end in the revolution.

• 4. Power, Pluralism, and Authoritarianism

  ›

  The Pahlavi state was not a single, stable political form across its decades in power. Reza Shah ruled as an autocrat until he abdicated on the 16th of September 1941, when his son Mohammad Reza took the throne. What followed was a period of relative political openness that lasted from 1941 to 1953. That pluralistic window closed when Mohammed Mossadegh was overthrown. After 1953, the dynasty returned to authoritarian rule, with a brief interval of single-party governance before the revolutionary collapse of 1979. The line of succession during those years was shaped by the 1906 constitution, which placed strict limits on who could inherit. No man descended from the Qajar dynasty could become heir apparent. The Shah also had to be of Iranian descent on both sides, meaning both father and mother had to be Iranian. These rules made all of Mohammad Reza's half-brothers ineligible. Until Ali Reza Pahlavi died in 1954, he served as his brother's heir presumptive as the Shah's only full brother.

  The Pahlavi dynasty produced a line of consorts whose lives tracked the turbulence of the dynasty itself. Reza Shah married Tadj ol-Molouk, daughter of Teymur Khan Ayromlou, in 1916, and she remained his consort until his abdication in 1941. His son Mohammad Reza Shah went through three wives. Princess Fawzia of Egypt, daughter of King Fuad I, married him in 1939 but was divorced in November 1948. Soraya Esfandiary-Bakhtiary, daughter of Khalil Esfandiary-Bakhtiary, became queen consort in February 1951 and was divorced in March 1958. Farah Diba, daughter of Sohrab Diba, married Mohammad Reza Shah in December 1959 and was elevated to empress consort in October 1967 when the Shah adopted the title Shahanshah. After her husband was deposed and then died in July 1980, Farah briefly served as regent from July until October 1980, when that regency expired. Her son Reza Pahlavi, born in 1960 and designated Crown Prince in October 1967, became the head of the House of Pahlavi after the regency ended.

• 6. After the Revolution

  ›

  When Mohammad Reza Shah was deposed on the 11th of February 1979, the monarchy ended, but the dynasty did not dissolve. The headship passed first to Crown Prince Reza Pahlavi, who became head of the house when his father died on the 27th of July 1980. His younger brother Ali Reza Pahlavi held the position of heir to that headship from 1980 until his death on the 4th of January 2011. After Ali Reza's death, the succession passed to Noor Pahlavi, the eldest daughter, who became heir on the 3rd of April 1992 and remains the incumbent. The dynasty's line of succession has grown more complex in later generations; one branch carries the surname Pahlavi Hillyer rather than Pahlavi, because the last Shah's sister Fatemeh married an American businessman, and their children do not use any royal titles at all. Reza Pahlavi, born in 1960, continues to hold the position of head of the house to this day.
