Place and territory are also crucial from cultural perspective because they enable communities to express their identity in a cultural landscape. Control of the territory of Nagorno-Karabakh was essential to express territoriality that is to protect language and identity. In addition, the article examines the exclusionary treatment of Karabakh Armenians by Azerbaijan and discrimination against them as the cause of the conflict and its intensity. The article also focuses on the desire for political self-rule as a necessary condition for nationhood.展开更多
