The Treaty of Turkmenchay was signed on February 21, 1828, between the Russian Empire and the Persian Empire, concluding the Russo-Persian War (1826-1828). This treaty marked a significant territorial loss for Persia, as it ceded parts of modern-day Armenia and Azerbaijan to Russia. It also established the borders between the two empires and granted Russia favorable trade rights in Persia. In addition to territorial changes, the treaty included provisions for the protection of Christian subjects in Persia and allowed for the establishment of Russian consulates. The Treaty of Turkmenchay solidified Russian influence in the region and set the stage for future conflicts between Persia and its neighbors.
