The Nagorno-Karabakh Republic is a republic in the South Caucasus recognised only by three non-United Nations (UN) states. Recognised by the UN as part of Azerbaijan, Nagorno-Karabakh controls most of the territory of the former Nagorno-Karabakh Autonomous Oblast and some of the surrounding area, giving it a border with Armenia to the west and Iran to the south.

Artsakh Republic or Republic of Artsakh

The predominantly Armenian-populated region of Nagorno-Karabakh was claimed by both the Azerbaijan Democratic Republic and the First Republic of Armenia when both countries became independent in 1918. After the Soviet Union established control over the area, it created the Nagorno-Karabakh Autonomous Oblast (NKAO) within the Azerbaijan SSR in 1923. In the final years of the Soviet Union, the region re-emerged as a source of dispute between Armenia and Azerbaijan. In 1991, a referendum held in the NKAO and the neighbouring Shahumian region resulted in a declaration of independence. Large-scale ethnic conflict led to the 1991–1994 Nagorno-Karabakh War, which ended with a ceasefire that left the current borders.
This is a rare country for philatelists because of its limited reongnition and relationship with foreign countries. But my good friend Serg, who is the first designer of NKR stamps helps philatelists by sending mint stamps, envelopes etc. I designed an airmail label for NKR, now which is being used as legal in NKR. Serg promoted the labels a lot and I am very happy in that. These envelopes sent by Serg with perfect postmarks. All letters are traveled via Armenia, The registered letters will have and extra Armenian barcode when they reach in Yerevan sorting center. Every year NKR issues beautiful thematic stamps. Eventhough this is not a UPU member country, there is no restriction for using own stamps for international letters. Thank You Serg for the beautiful covers into my collection.
