Nader Shah, founder of the Afsharid dynasty, is crowned Shah of Iran.

Nader Shah Afshar was the founder of the Afsharid dynasty of Iran and one of the most powerful rulers in Iranian history, ruling as shah of Iran (Persia) from 1736 to 1747, when he was assassinated during a rebellion. He fought numerous campaigns throughout the Middle East, the Caucasus, Central Asia, and South Asia, emerging victorious from the battles of Herat, Mihmandust, Murche-Khort, Kirkuk, Yeghevārd, Khyber Pass, Karnal, and Kars. Because of his military genius, some historians have described him as the Napoleon of Persia, the Sword of Persia, or the Second Alexander. Nader belonged to the Turkoman Afshars, one of the seven Qizilbash tribes that helped the Safavid dynasty establish their power in Iran.

The Afsharid dynasty was an Iranian dynasty founded by Nader Shah of the Qirqlu clan of the Turkoman Afshar tribe, ruling over the Afsharid Empire.

The monarchs of Iran ruled for over two and a half millennia, beginning as early as the 7th century BC and enduring until the 20th century AD. The earliest Iranian king is generally considered to have been either Deioces of the Median dynasty or Cyrus the Great of the Achaemenid dynasty. The last Iranian king was Mohammad Reza Pahlavi of the Pahlavi dynasty (1925–1979), which was overthrown by the Islamic Revolution. Since then, Iran has been governed as an Islamic republic.
