Unification of Iran (1779–1796) in the context of "Qajar Iran"

The Guarded Domains of Iran, alternatively the Sublime State of Iran and commonly called Qajar Iran, Qajar Persia or the Qajar Empire, was the Iranian state under the rule of the Qajar dynasty, which was of Turkic origin, specifically from the Qajar tribe, from 1789 to 1925. The Qajar family played a pivotal role in the Unification of Iran (1779–1796), 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.

In the Caucasus, the Qajar dynasty permanently lost much territory to the Russian Empire over the course of the 19th century, comprising modern-day eastern Georgia, Dagestan, Azerbaijan, and Armenia. Despite its territorial losses, Qajar Iran reinvented the Iranian notion of kingship and maintained relative political independence, but faced major challenges to its sovereignty, predominantly from the Russian and British empires. Foreign advisers became powerbrokers in the court and military. They eventually partitioned Qajar Iran in the 1907 Anglo-Russian Convention, carving out Russian and British influence zones and a neutral zone.
