Legally recognized as a part of Azerbaijan, it declared independence in 1991 and then defended that independence in a war with Azerbaijan that lasted until 1994. While it enjoys no international recognition of sovereignty, Nagorno-Karabakh has been de facto independent since its declaration and has been supported militarily and economically by neighboring Armenia.
