Full-scale war between Armenian and Azerbaijani forces over the former NKAO: Armenian forces take Shusha (Shushi) and open the Lachin corridor in May 1992, then in 1993 seize seven Azerbaijani districts around the enclave — condemned in four UN Security Council resolutions — while roughly 700,000 Azerbaijanis are displaced, alongside hundreds of thousands displaced between the two republics.
