Nagorno Karabakh stamps

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.

Artsakh, officially the Republic of Artsakh or the Republic of Nagorno-Karabakh, was a breakaway state in the South Caucasus whose territory was internationally recognised as part of Azerbaijan. Between 1991 and 2023, Artsakh controlled parts of the former Nagorno-Karabakh Autonomous Oblast of the Azerbaijani Soviet Socialist Republic, including its capital Stepanakert. It had been an enclave within Azerbaijan from the 2020 Nagorno-Karabakh war until the 2023 Azerbaijani offensive, when the Azerbaijani military took control over the remaining territory controlled by Artsakh.

Before, Nagorno-Karabakh was 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. In this period Artsakh issued its own stamps.
