Nagorno-Karabakh is a geographical area near the border between Armenia and Azerbaijan.

It is a mountainous and heavily-forested patch of land that sits inside the territory of ex-Soviet Azerbaijan.

Today the vast majority of the population of Nagorno Karabakh is Armenian.

Under international law, Nagorno-Karabakh is recognised as part of Azerbaijan. But the ethnic Armenians who make up the vast majority of the population reject Azeri rule. They have been running their own affairs, with support from Armenia, since Azerbaijan’s troops were pushed out in a war in the 1990s.

The conflict has been marked by controversies and atrocities on both sides. Our intention is not to cover every aspect but to give an accessible overview to those unfamiliar with the conflict.

- The region is a strategic area for oil and gas pipelines.
