Treaty of Gulistan: The Russo-Persian War of 1804-1813 comes to a close with the signing of the Treaty of Gulistan, under which terms Qajar Iran agrees to cede the bulk of its Caucasian territories, which comprise much of modern Dagestan, Georgia, Armenia, and Azerbaijan, to the Russian Empire.

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.
