The war was the most destructive ethnic conflict in both terms of lives and property that emerged after the Soviet Union collapsed in December 1991. Interethnic fighting between the two broke out shortly after the parliament of Nagorno-Karabakh, an autonomous oblast in Azerbaijan, voted to unify the region with Armenia on February 20, 1988. Along with the secessionist movements in the Baltic republics of Estonia, Latvia, and Lithuania, the succeeding movement characterized and played a large role in bringing the downfall of the Soviet Union. As Azerbaijan declared its independence from the Soviet Union and removed the powers held by the enclave’s government, the Armenian majority voted to secede from Azerbaijan, and in the process proclaimed the enclave the Republic of Nagorno-Karabakh.
Full-scale fighting erupted in the late winter of 1992. International mediation by several groups including Europe’s OSCE failed to bring an end resolution that both sides could work with. In the spring of 1993, Armenian forces captured regions outside the enclave itself, threatening the involvement of other countries in the region. By the end of the war in 1994, the Armenians were in full control of not only the mountainous enclave but also held and currently control approximately 14% of Azerbaijan’s territory. A Russian-brokered cease fire was signed in May of 1994 and peace talks, mediated by the OSCE Minsk Group, have been held ever since by Armenia and Azerbaijan.
