Russo-Persian War (1826–1828)Armenia
The Russo-Persian War of 1826–1828 was the last major military conflict between the Russian Empire and Persia. After the Treaty of Gulistan that concluded the previous Russo-Persian War in 1813, peace reigned in the Caucasus for thirteen years. However, Fath 'Ali Shah, constantly in need of foreign subsidies, relied on the advice of British agents, who advised him to reconquer the territories lost to Russian Empire and pledged their support for military action. The matter was decided upon in spring 1826, when a bellicose party of Abbas Mirza prevailed in Tehran and the Russian minister, Aleksandr Sergeyevich Menshikov, was placed under house arrest. The war ended in 1828 following the occupation of Tabriz. The war had even more disastrous results for Persia than the 1804-1813 war, as the ensuing Treaty of Turkmenchay stripped Persia of its last remaining territories in the Caucasus, which comprised all of modern Armenia, the southern remainder of modern Azerbaijan, and modern Igdir in Turkey. The war marked the end of the era of the Russo-Persian Wars, with Russia now the unquestioned dominant power in the Caucasus.
