Эриванское ханство
The Russo-Persian War (1826-1828) began due to Persian demand to reconquer the territories lost to Russia between 1804 and 1813. At first, the Persians repulsed the Russians from the South Caucasus in 1826. However, Russian general and commander of the Russian army, Ivan Paskevich, reconquered South Caucasus and extended its territories to include the Erivan Khanate in 1827.
