The Pahlavi dynasty (Persian: خاندان پهلوی) is the last Iranian royal dynasty, ruling for almost 54 years between 1925 and 1979. The dynasty was founded by a non-aristocratic Mazanderani soldier in modern times, who took on the name of the Pahlavi language spoken in the pre-Islamic Sasanian Empire in order to strengthen his nationalist credentials.
The dynasty replaced the Qajar dynasty in the early 1920s, beginning on 14 January 1921 when 41-year-old soldier Reza Khan was promoted by British General Edmund Ironside to lead the British-run Persian Cossack Brigade. About a month later, under British direction, Reza Khan's 3,000-4,000 strong detachment of the Cossack Brigade reached Tehran in what became known as the 1921 Persian coup d'état. The rest of the country was taken by 1923, and by October 1925 the Majlis agreed to depose and formally exile Ahmad Shah Qajar. The Majlis declared Reza Pahlavi as the new Shah of Iran on 12 December 1925, pursuant to the Persian Constitution of 1906. Initially, Pahlavi had planned to declare the country a republic, as his contemporary Atatürk had done in Turkey, but abandoned the idea in the face of British and clerical opposition.
The dynasty ruled Iran for 28 years as a form of constitutional monarchy from 1925 until 1953, and following the overthrow of the democratically elected prime minister, for a further 26 years as a more autocratic monarchy until the dynasty was itself overthrown in 1979.

In 1878, Reza Khan was born at the village of Alasht in Savadkuh County, Mazandaran Province. His parents were Abbas Ali Khan and Noushafarin Ayromlou. His mother was a Muslim immigrant from Georgia (then part of the Russian Empire), whose family had emigrated to mainland Qajar Iran after Iran was forced to cede all of its territories in the Caucasus following the Russo-Persian Wars several decades prior to Reza Shah's birth. His father was a Mazandarani, commissioned in the 7th Savadkuh Regiment, and served in the Anglo-Persian War in 1856.

The former constitution of Iran specifically provided that only a male who was not descended from Qajar dynasty could become the heir apparent. This made all half-brothers of Mohammad Reza ineligible to become heirs to the throne. Until his death in 1954, the Shah's only full brother Ali Reza was his heir presumptive.
It constitution also required the Shah to be of Iranian descent, meaning that his father and mother are Iranian.

2. The Shah gives another account for his separation with Fawzia. “For reasons still obscure to medical science, Queen Fawzia bore only one child; thus unfortunately no male heir issued from our marriage. Under the Persian Constitution the crown must pass by direct line of descent to a male heir. This rules out not only my daughter but also my three sisters. The Constitution further stipulates that no one descended from the previous Qajar dynasty is eligible to become king. Since two of my father’s wives were of Qajar blood, my half-brothers who are their sons are ineligible. In fact I had only one brother not related to the Qajar line, and to my sorrow he was to die in an aeroplane crash in 1954. With these limitations it is no wonder that my advisors felt it important for my wife to bear a son. It is true that the Constitution might have been amended, but the dimate of opinion seemed opposed to tampering with the provisions relating to the royal succession. Besides, I was young and, quite apart from the constitutional factor, I wanted more children. When Queen Fawzia went to Egypt on an extended stay, we decided on a divorce.” Please see Mission for My Country His Imperial Majesty Mohammad Reza Shah Pahiavi, Hutchinson and Co.
