Qajar Iran, also referred to as Qajar Persia, the Qajar Empire, Sublime State of Persia, officially the Sublime State of Iran and also known as the Guarded Domains of Iran, was an Iranian state ruled by the Qajar dynasty, which was of Turkic origin, specifically from the Qajar tribe, from 1789 to 1925. The Qajar family took full control of Iran in 1794, deposing Lotf 'Ali Khan, the last Shah of the Zand dynasty, and re-asserted Iranian sovereignty over large parts of the Caucasus. In 1796, Agha Mohammad Khan Qajar seized Mashhad with ease, putting an end to the Afsharid dynasty. He was formally crowned as Shah after his punitive campaign against Iran's Georgian subjects.

The Zand dynasty was an Iranian dynasty, founded by Karim Khan Zand that initially ruled southern and central Iran in the 18th century. It later quickly came to expand to include much of the rest of contemporary Iran as well as parts of Iraq. The lands of present-day Armenia, Azerbaijan, and Georgia were controlled by khanates which were de jure part of the Zand realm, but the region was de facto autonomous. The island of Bahrain was also held for the Zands by the autonomous Al-Mazkur sheikhdom of Bushire.
