The history of Iran is deeply intertwined with the monarchs who ruled over the land for centuries. From ancient Persia to the 20th century, various dynasties led by shahs shaped Iran’s political, cultural, and religious identity. The title ‘Shah’ refers to the king or emperor of Iran, and throughout history, this title has been held by leaders from different dynasties, such as the Achaemenids, Parthians, Sassanids, Safavids, Afsharids, Zands, Qajars, and Pahlavis. This topic presents a detailed list of Shahs of Iran, categorized by their respective dynasties, and explains their impact on the nation’s evolution over time.

- Later rulers were less effective, and the dynasty eventually fell to the Qajars.
Qajar Dynasty (1794-1925)
The Qajar period was marked by internal weakness, foreign interference, and the loss of territories to Russia and Britain. Despite this, it laid foundations for modern reforms.

- Reza Shah Pahlavi (1925-1941)– Former military officer who ended Qajar rule; introduced industrialization and secular reforms.
- Mohammad Reza Shah Pahlavi (1941-1979)– Continued modernization, but faced increasing opposition, which led to his eventual overthrow during the 1979 Islamic Revolution.
The End of the Monarchy
In 1979, the Iranian monarchy officially ended with the establishment of the Islamic Republic under Ayatollah Khomeini. The last Shah, Mohammad Reza Pahlavi, went into exile, and the title of Shah ceased to exist. Since then, Iran has been governed as a theocratic republic, and the royal title has become part of history.
