The frozen conflict over currently largely Armenian-populated region of Nagorno-Karabakh within the Republic of Azerbaijan began when in 1988 the Armenian majority of Nagorno-Karabakh demanded autonomy with demonstrations and persecutions against ethnic Azeris following in Armenia. This led to anti-Armenian rioting in Azerbaijan, with Azerbaijani militias beginning their effort to expel Armenians from the enclave. In 1992 a war broke out and pogroms of Armenians and Azeris forced both groups to flee their homes. In 1994, a Russian-brokered ceasefire ended the war but more than 1 million ethnic Armenians and Azeris are still not able to return home. The conflict over Nagorno-Karabakh remains unresolved despite negotiations, that are ongoing since 1992 under the aegis of the Minsk Group of the OSCE, to resolve the conflict peacefully.
