The Treaty of Gulistan was a peace treaty concluded between the Russian Empire and Qajar Iran on 24 October 1813 in the village of Gulistan as a result of the first full-scale Russo-Persian War. The peace negotiations were precipitated by the successful storming of Lankaran by General Pyotr Kotlyarevsky on 1 January 1813. It was the first of a series of treaties signed between Qajar Iran and Imperial Russia that forced Persia to cede the territories that formerly were part of Iran.

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.
