P=have O=don’t have it

Nagorno-Karabakh, meaning "Mountainous Karabakh," also known as Artsakh, is a landlocked region in the South Caucasus, within the mountainous range of Karabakh, lying between Lower Karabakh and Zangezur, and covering the southeastern range of the Lesser Caucasus mountains. The region is mostly mountainous and forested.

Nagorno-Karabakh is a disputed territory, internationally recognized as part of Azerbaijan, but most of the region is governed by the Republic of Artsakh (formerly named Nagorno-Karabakh Republic), a de facto independent state with Armenian ethnic majority established on the basis of the Nagorno-Karabakh Autonomous Oblast of the Azerbaijan Soviet Socialist Republic. Azerbaijan has not exercised political authority over the region since the advent of the Karabakh movement in 1988. Since the end of the Nagorno-Karabakh War in 1994, representatives of the governments of Armenia and Azerbaijan have been holding peace talks mediated by the OSCE Minsk Group on the region's disputed status.
