Western Azerbaijan (political concept)

Western Azerbaijan is an irredentist political concept that is used in the Republic of Azerbaijan mostly to refer to the territory of the Republic of Armenia. Azerbaijani statements claim that the territory of the modern Armenian republic were lands that once belonged to Azerbaijanis. Its claims are primarily hinged over the contention that the current Armenian territory was under the rule of various Turkic tribes, empires and khanates from the late medieval period until the Treaty of Turkmenchay signed after the Russo-Persian War, 1826-1828. The concept has received official sanction by the government of Azerbaijan, and has been used by its current president, Ilham Aliyev, who has repeatedly stated that the territory of Armenia is a part of "ancient Turk and Azerbaijani land."
