Nagorno-Karabakh: A History of the Autonomous Oblast
The region of Nagorno-Karabakh has long been a focal point of geopolitical tension in the Caucasus. Its modern history is defined by a complex struggle for autonomy and identity, beginning with the brief independence of the First Republic of Armenia and the Azerbaijan Democratic Republic between 1918 and 1920. Following the Sovietization of these republics, the Kavbiuro (the Bolshevik Party's Caucasian Bureau) decided to place the area within the Azerbaijan SSR, though it was granted broad regional autonomy.
The Establishment of the NKAO
On July 7, 1923, the Nagorno-Karabakh Autonomous Oblast (NKAO) was formally established. The administrative center was moved to Stepanakert, named in honor of the revolutionary Stepan Shaumian. The oblast initially covered an area of 4,161 km² (1,607 sq mi).
The inclusion of Shusha, a principal city of the region, was a point of early contention. Initially, Shusha and its surrounding villages were to be excluded from the autonomy because they were predominantly Azerbaijani, following the massacre and expulsion of the majority Armenian population. However, this decision was reversed in 1923, and Shusha was joined to the NKAO despite protests from Muslim villages that preferred its inclusion in the Kurdistan uezd (a Soviet administrative district).

Demographic Shifts and Political Appeals
Demographics within the NKAO shifted significantly throughout the Soviet era. According to the 1926 Soviet census, the population stood at 125,200, with Armenians making up 89.2 percent. By the 1989 census, the Armenian share of the population had dropped to 76.9 percent. This decline was attributed to several factors: the Azerbaijani authorities' policy of settling Azerbaijanis in the region, the out-migration of Armenians, and a higher birthrate among the Azerbaijani population.
Throughout the mid-20th century, Armenian intellectuals and leaders periodically petitioned Moscow to transfer the oblast to the Armenian SSR. Notable attempts included:
- 1945: First Secretary Grigory Arutinov appealed to Joseph Stalin, but the request was vetoed by Azerbaijan's Mir Jafar Baghirov.
- 1956: Following Nikita Khrushchev's "Secret Speech," Armenian Catholicos Vazgen I wrote to Nikolai Bulganin regarding the region's status.
- 1962: Residents of the NKAO appealed directly to Khrushchev, citing grievances with Baku and requesting a transfer to either Soviet Armenia or the Russian SFSR.
- 1966: An appeal signed by 1,906 cultural and intellectual figures—including Martiros Saryan, Yervand Kochar, Hamo Sahyan, and Paruyr Sevak—was endorsed by Armenian leadership but vetoed by Baku, reportedly with the support of Mikhail Suslov.
Tightening Control and the Path to Conflict
The political climate shifted further in 1969 when Heydar Aliyev assumed leadership of the Azerbaijani SSR. Aliyev sought to tighten Baku's control over the NKAO and alter its demographics. In 1973–74, he purged the oblast's leadership, labeling them "Armenian nationalists," and appointed Boris Kevorkov, an Armenian from outside the region, as First Secretary. In 1977, author Sero Khanzadyan continued the push for annexation in an open letter to Leonid Brezhnev.
The arrival of Mikhail Gorbachev's policies of glasnost (openness) and perestroika (restructuring) provided the catalyst for a democratic mass movement. On February 20, 1988, the Supreme Soviet of the NKAO voted to unify with Soviet Armenia, sparking open conflict between the local Armenian population and the Azerbaijani government.
By the end of 1991, this escalation evolved into the First Nagorno-Karabakh War. On November 26, 1991, the Supreme Soviet of Azerbaijan formally abolished the oblast's autonomous status. In response, and with the support of Armenia, the majority Armenian population declared the independence of the Nagorno-Karabakh Republic on December 10, 1991.
