The Russo-Persian War of 1826–1828 was the last major military conflict between the Russian Empire and Qajar Iran, which was fought over territorial disputes in the South Caucasus region.
Initiated by Russian expansionist aims and intensified by Iranian resistance, the war witnessed significant military engagements, including the Battle of Ganja and Capture of Erivan. The Iranians were initially successful, catching the Russian forces of Yermolov off-guard. They were aided by local uprisings against Russian garrisons in Talish, Ganja, Shirvan, Shakki, and other areas. However Russian reinforcements under the newly appointed General Ivan Paskevich turned the war decisively in Russia's favor, capturing the important city of Tabriz in northwestern Iran.
