Nagorno-Karabakh, an Armenian-majority enclave inside Soviet Azerbaijan, votes to unify with Armenia, triggering intercommunal violence and setting the stage for decades of conflict.
A Russian-brokered ceasefire ends the First Nagorno-Karabakh War, leaving Armenian forces in control of the enclave and surrounding Azerbaijani territories, displacing roughly 700,000 Azerbaijanis.
Azerbaijan launches a 44-day offensive in September, recapturing significant territory including the city of Shusha; a Russian-brokered ceasefire in November ends the Second Karabakh War with Armenia ceding most of its gains from 1994.

Over 100,000 ethnic Armenians flee Nagorno-Karabakh within days of the offensive, effectively ending nearly three decades of Armenian presence in the enclave.
Armenia and Azerbaijan continue negotiations toward a formal peace treaty, but disputes over border demarcation, transit routes, and constitutional language keep a final agreement unsigned.
