The war was a major escalation of the long-unresolved First Nagorno-Karabakh War (1988–1994), with deep disputes over the status of Nagorno-Karabakh and surrounding occupied territories persisting between Azerbaijan and Armenia. On the morning of 27 September 2020, Azerbaijan launched a military offensive along the established line of contact, with Turkey providing significant military support, including drone technology.
Fighting over 44 days was concentrated in the less mountainous southern districts of Nagorno-Karabakh. Azerbaijan made extensive use of drones, long-range artillery, and missile strikes, alongside information warfare. Three internationally brokered ceasefires failed. The conflict culminated in Azerbaijan's capture of Shusha and a ceasefire agreement signed on 10 November 2020.
The ceasefire produced a significant shift in territorial control, with Azerbaijan regaining substantial areas. Approximately 2,000 Russian soldiers were deployed as peacekeepers along the Lachin corridor. Anti-government protests erupted in Armenia. Reports of mistreatment of Armenian prisoners of war led to a case at the International Court of Justice, and a 2023 Azerbaijani offensive completed full Azerbaijani control of Nagorno-Karabakh.
