evidence: Nagorno-Karabakh is a mountainous region internationally recognized as part of Azerbaijan. Roughly 120,000 ethnic Armenians were living there out of the population of a little over 140,000. Under the Soviet Union, which included both Azerbaijan and Armenia, Nagorno-Karabakh became an autonomous region within the republic of Azerbaijan. With the breakup of the Soviet Union, Karabakh declared itself an independent republic. The region came under the control of ethnic Armenian forces backed by the Armenian military in a six-year war that ended in 1994 and killed about 30,000 people. Nagorno-Karabakh became de facto independent, with a self-proclaimed government in Stepanakert, but was heavily reliant on close economic, political and military support from Armenia, according to Global Conflict Tracker. [...] On Sept. 19, Azerbaijan launched a military offensive and in 24 hours ended the 35-year conflict over the territory. The self-declared government of Nagorno-Karabakh agreed to capitulate and dismantle its armed forces, leading to the cease-fire.
