Artsakh, officially the Republic of Artsakh or the Republic of Nagorno-Karabakh, was a breakaway state in the South Caucasus whose territory was internationally recognised as part of Azerbaijan. Between 1991 and 2023, Artsakh controlled parts of the former Nagorno-Karabakh Autonomous Oblast of the Azerbaijani Soviet Socialist Republic, including its capital Stepanakert. It had been an enclave within Azerbaijan from the 2020 Nagorno-Karabakh war until the 2023 Azerbaijani offensive, when the Azerbaijani military took control over the remaining territory controlled by Artsakh. Its only overland access route to Armenia after the 2020 war was via the five kilometres (3.1 mi)–wide Lachin corridor, which was placed under the supervision of Russian peacekeeping forces.
The OSCE Minsk Group was created in 1992 by the Conference on Security and Cooperation in Europe (CSCE), now Organization for Security and Co-operation in Europe (OSCE), to encourage a peaceful, negotiated resolution to the conflict between Azerbaijan and Armenia over Nagorno-Karabakh.
The Nagorno-Karabakh conflict is an ethnic and territorial conflict between Armenia and Azerbaijan over the region of Nagorno-Karabakh, inhabited mostly by ethnic Armenians until 2023, and seven surrounding districts, inhabited mostly by Azerbaijanis until their expulsion during the 1990s. The Nagorno-Karabakh region was entirely claimed by and partially controlled by the breakaway Republic of Artsakh, but was recognized internationally as part of Azerbaijan. Azerbaijan gradually re-established control over Nagorno-Karabakh region and the seven surrounding districts.
Presidential elections were held in the Nagorno-Karabakh Republic on 19 July 2007. Incumbent president Arkady Ghukasyan was constitutionally barred from seeking a third term and endorsed Bako Sahakyan, who was the head of the National Security Service. Sahakyan was supported by the ruling Democratic Party of Artsakh, two opposition parties and the Armenian government.
