Nagorno-Karabakh

Syllabus: General Studies Paper 2

The conflict between Armenia and Azerbaijan over Nagorno-Karabakh has been at the centre of three major wars and multiple clashes for decades.

Nagorno-Karabakh 

  • Nagorno-Karabakh is a mountainous and heavily forested region that under international law is recognised as part of Azerbaijan.
  • However, ethnic Armenians who constitute the vast majority of the population there reject Azeri rule (the legal system of Azerbaijan).

Nagorno-Karabakh Dispute

  • It is a disputed territory internationally recognized as part of Azerbaijan but mostly governed by the Republic of Artsakh, de facto independent state with an Armenian ethnic majority backed by neighbouring Armenia. 
  • Modern-day Armenia and Azerbaijan became part of the Soviet Union when it formed in the 1920s. Nagorno-Karabakh was an ethnic-majority Armenian region, but the Soviets gave control over the area to Azerbaijani authorities.
  • It was only as the Soviet Union began to collapse in the late 1980s that Nagorno-Karabakh’s regional parliament officially voted to become part of Armenia.
  • Azerbaijan sought to suppress the separatist movement, while Armenia backed it. This led to full-scale war. Armenian forces gained control of Nagorno-Karabakh and areas adjacent to it before a Russian-brokered ceasefire was declared in 1994.
  • After that deal, Nagorno-Karabakh remained part of Azerbaijan, but since then has mostly been governed by a separatist, self-declared republic run by ethnic Armenians and backed by the Armenian government.

Strategic Significance

  • The energy-rich Azerbaijan has built several gas and oil pipelines across the Caucasus (the region between the Black Sea and the Caspian Sea) to Turkey and Europe.
  • Some of these pipelines pass close to the conflict zone (within 16 km of the border).
  • In an open war between the two countries, the pipelines could be targeted, which would impact energy supplies and may even lead to higher oil prices globally.
