(1750–79), Iranian dynasty that ruled southern Iran.

Following the death of the Afshārid ruler Nāder Shāh (1747), Karīm Khān Zand (Karīm Khān Zand (Moḥammad)) became one of the major contenders for power. By 1750 he had sufficiently consolidated his power to proclaim himself as vakīl (regent) for the Ṣafavid Esmāʿīl III. Karīm Khān never claimed the title of shāhanshāh (“king of kings”); instead he maintained Esmāʿīl as a figurehead. Karīm Khān, with 30 years of benevolent rule, gave southern Iran a much needed respite from continual warfare. He encouraged agriculture and entered into trade relations with Great Britain. His death in 1779 was followed by internal dissensions and disputes over successions. Between 1779 and 1789 five Zand kings ruled briefly. In 1789 Loṭf ʿAlī Khān (Loṭf ʿAlī Khān Zand) (ruled 1789–94) proclaimed himself as the new Zand king and took energetic action to put down a rebellion led by Āghā Moḥammad Khān Qājār that had begun at Karīm Khān's death. Outnumbered by the superior Qājār forces, Loṭf ʿAlī Khān was finally defeated and captured at Kermān in 1794. His defeat marked the final eclipse of the Zand dynasty, which was supplanted by that of the Qājārs.
