Nader Shah Afshar (born Nader Qoli; Persian: نادرشاه افشار; 6 August 1698 or 22 October 1688 – 20 June 1747) was the founder of the Afsharid dynasty of Iran and one of the most powerful rulers in Iranian history, ruling as the emperor 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. Nader belonged to the Turkoman Afshars, one of the seven Qizilbash tribes that helped the Safavid dynasty establish their power in Iran.
Nader rose to power during a period of chaos in Iran after a rebellion by the Hotaki Afghans had overthrown the weak emperor Soltan Hoseyn (r. 1694–1722), while the arch-enemy of the Safavids, the Ottoman Empire, as well as the Russian Empire, had seized Iranian territory for themselves. Nader reunited the Iranian realm and removed the invaders. He became so powerful that he decided to depose the last members of the Safavid dynasty, which had ruled Iran for over 200 years, and declared himself Shah in 1736. His numerous campaigns created a great empire that, at its maximum extent, briefly encompassed all or part of modern-day Afghanistan, Armenia, Azerbaijan, Bahrain, Georgia, India, Iran, Iraq, Turkey, Turkmenistan, Oman, Pakistan, Uzbekistan, the North Caucasus, and the Persian Gulf, but his military spending had a ruinous effect on the Iranian economy.
