Nedir Şah, who had been a commander in Safavid state, came to power in Iran in 1736. Nedir Şah was descended from the Owşar tribe of the Oguz. He defeated the Uveysi people, rulers of Iran for a short period, and expelled them from Iran. Using his military might, Nedir Şah captured the throne. On Nedir Şah’s ascent to the throne, Iran gained many things. First of all, it regained the land which had been taken by the Ottoman Empire earlier. In addition, Nedir Şah defeated Babür Şah and took over Delhi.

After Nedir Şah’s death in 1747, his descendant Adyl Şah was not able to prolong the reign of the Owşar tribe. In 1750, the Owşar dynasty reached its end.
