First Nagorno-Karabakh War
The First Nagorno-Karabakh War was an ethnic and territorial conflict that took place from February 1988 to May 1994 in the enclave of Nagorno-Karabakh in southwestern Azerbaijan between the majority ethnic Armenians of Nagorno-Karabakh backed by Armenia, and the Republic of Azerbaijan with support from Turkey. As the war progressed, Armenia and Azerbaijan, both former Soviet republics, entangled themselves in protracted, undeclared mountain warfare in the mountainous heights of Karabakh as Azerbaijan attempted to curb the Karabakh Movement.
The enclave's parliament had voted in favor of uniting with Armenia and a referendum, boycotted by the Azerbaijani population of Nagorno-Karabakh, was held, in which a 99.89% voted in favor of independence with an 82.2% turnout. The demand to unify with Armenia began in a relatively peaceful manner in 1988; in the following months, as the Soviet Union disintegrated, it gradually grew into an increasingly violent conflict between Armenians and Azerbaijanis, resulting in ethnic cleansing, including the Sumgait and Baku pogroms directed against Armenians, and the Gugark pogrom and Khojaly Massacre directed against Azerbaijanis.
Inter-ethnic clashes between the two broke out shortly after the parliament of the Nagorno-Karabakh Autonomous Oblast in Azerbaijan voted to unite the region with Armenia on 20 February 1988. The declaration of secession from Azerbaijan was the culmination of a territorial conflict. As Azerbaijan declared its independence from the Soviet Union and removed the powers held by the enclave's government, the Armenian majority voted to secede from Azerbaijan and in the process proclaimed the unrecognized Republic of Nagorno-Karabakh.
Full-scale fighting erupted in early 1992. Turkey sent mercenaries to fight for Azerbaijan and assisted in blockading all land transit to Armenia, including humanitarian aid. International mediation by several groups including the Conference for Security and Co-operation in Europe failed to bring an end resolution that both sides could work with. In early 1993, Armenian forces captured seven Azerbaijani-majority districts outside the enclave itself, threatening the involvement of other countries in the region. By the end of the war in 1994, the Armenians were in full control of the enclave, in addition to surrounding Azerbaijani territories, most notably the Lachin corridor – a mountain pass that links Nagorno-Karabakh with mainland Armenia. A Russian-brokered ceasefire was signed in May 1994.
As a result of the conflict, approximately 724,000 Azerbaijanis were expelled from Armenia, Nagorno-Karabakh and the surrounding territories, while 300,000–500,000 Armenians living in Azerbaijan or Armenian border areas were displaced. After the end of the war and over a period of many years, regular peace talks between Armenia and Azerbaijan were mediated by the OSCE Minsk Group but failed to result in a peace treaty. This left the Nagorno-Karabakh area in a state of legal limbo, with the Republic of Artsakh remaining de facto independent but internationally unrecognized. Ongoing tensions persisted, with occasional outbreaks of armed clashes. Armenian forces occupied approximately 9% of Azerbaijan's territory outside the enclave until the Second Nagorno-Karabakh War in 2020.
Background
The territorial ownership of Nagorno-Karabakh today is heavily contested between Armenians and Azerbaijanis. The current conflict has its roots in events following World War I. Amid the dissolution of the Russian Empire in November 1917 and seizure of power by the Bolsheviks, the three main ethnic groups of the South Caucasus, Armenians, Azerbaijanis and Georgians, struggled to come to an agreement on the nature of political government in the region. An attempt at shared political authority in the form of the Transcaucasian Federation in the spring of 1918 came to naught in the face of an invasion by the forces of the Ottoman Empire. In May 1918, separate Armenian, Azerbaijani and Georgian national republics declared their formal independence from Russia.Armenian–Azerbaijani war
Fighting soon broke out between the First Republic of Armenia and the Azerbaijan Democratic Republic in three regions in particular: Nakhchivan, Zangezur and Karabakh itself.Armenia and Azerbaijan quarreled over the prospective boundaries of the three regions. The Armenians of Nagorno-Karabakh sought to unite the region with the Armenian republic. Following the defeat of the Ottoman Empire in World War I, forces led by Armenian general Andranik Ozanian entered Karabakh and made for the regional capital of Shusha in December 1918 when they were stopped by newly arrived British troops. The British commander suggested Andranik desist from marching on to Shusha and allow Armenia's and Azerbaijan's territorial disputes be left to the diplomats meeting at the forthcoming Paris Peace Conference. The British in the meantime decided to appoint Khosrov bey Sultanov, an Azerbaijani statesman, as provisional governor, but insisted that all sides await the decision made at the peace conference. Intermittent fighting broke out shortly after and accelerated following the British pull-out in early 1919. The violence culminated in Shusha's partial destruction by Azerbaijani forces in April 1920.
Soviet division
In April 1920, the Soviet Eleventh Army invaded the Caucasus and within two years, the Caucasian republics were formed into the Transcaucasian SFSR of the Soviet Union. The Bolsheviks created a seven-member committee, the Caucasus Bureau. Established under the auspices of the People's Commissariat for Nationalities, the Kavburo was tasked with resolving a myriad of national-related issues in the Caucasus. On 4 July 1921 the committee voted 4–3 in favor of assigning Nagorno-Karabakh to the newly created Soviet Socialist Republic of Armenia, but a day later the Kavburo reversed its decision and voted to leave the region within the Azerbaijan SSR.Historians to this day debate the reason for the Kavburo's last-minute reversal. Early scholarship argued that the decision was driven by a Soviet nationality policy that sought to create divisions within different ethnic and national groups. In addition to Nagorno-Karabakh, the Soviets also turned Nakhichevan, a region with a large Armenian minority population, into an exclave of Azerbaijan, separated by Armenia's border. More recent research has pointed to geography, Soviet economic policy, and ensuring close relations with Turkish nationalist leader Mustafa Kemal as factoring heavily in the Soviet decision-making.
In 1923, the Nagorno-Karabakh Autonomous Oblast was established with a 94% Armenian population, and its capital was shifted from Shusha to Khankendi, later renamed Stepanakert after the Armenian Bolshevik revolutionary Stepan Shahumian. However, the town’s original Armenian name, Vararakn., remained in use by Armenians until 1923.
Over the following decades of Soviet rule, the Nagorno-Karabakh Armenians retained a strong desire to reunite with Armenia. A number of Armenian Communist Party officials attempted to persuade Moscow to reconsider the question, to little avail. In 1936, First Secretary of the Communist Party of Armenia Aghasi Khanjian was murdered by the deputy head of the NKVD Lavrentiy Beria after submitting Armenian grievances to Stalin, which included requests to return Nagorno-Karabakh and Nakhichevan to Armenia. The Armenians of the region frequently complained over the span of Soviet rule that their cultural and national rights were continually trampled upon by the Soviet Azerbaijani authorities in Baku.
Prelude
Revival of the Karabakh issue
After Stalin's death, Armenian discontent began to be voiced. In 1963, around 2,500 Karabakh Armenians signed a petition calling for Karabakh to be put under Armenian control or to be transferred to Russia. The same year saw violent clashes in Stepanakert, leading to the death of 18 Armenians. In 1965 and 1977, there were large demonstrations in Yerevan calling to unify Karabakh with Armenia.In 1985, Mikhail Gorbachev came to power as the new general secretary of the Soviet Union and began implementing plans to reform the Soviet Union through his policies of perestroika and glasnost. Many Armenians took advantage of the unprecedented opening of political expression offered by his policies and brought the issue of Nagorno-Karabakh back into the spotlight. Karabakh Armenian leaders complained that the region had neither Armenian language textbooks in schools nor in television broadcasting, and that Azerbaijan's Communist Party General Secretary Heydar Aliyev had attempted to "Azerify" the region by increasing the influence and number of Azerbaijanis living in Nagorno-Karabakh while at the same time pressuring its Armenian population to emigrate. Over the course of seventy years, the Armenian population of Karabakh had dwindled to nearly three-quarters of the total population by the late 1980s.
In February 1988, Armenians began protesting and staging workers' strikes in Yerevan, demanding unification with the enclave. On 20 February 1988, the leaders of the regional Soviet of Karabakh voted in favour of unifying the autonomous region with Armenia in a resolution.
Operation Ring
In early 1991, President Gorbachev held a special countrywide referendum called the Union Treaty which would decide if the Soviet republics would remain together. Newly elected non-communist leaders had come to power in the Soviet republics, including Boris Yeltsin in Russia, Levon Ter-Petrosyan in Armenia, and Ayaz Mutalibov in Azerbaijan. Armenia and five other republics boycotted the referendum.As many Armenians and Azerbaijanis in Karabakh began acquiring arms located in caches throughout Karabakh, Mutalibov turned to Gorbachev for support in launching a joint military operation in order to disarm Armenian militants in the region. Codenamed Operation Ring, Soviet forces, acting in conjunction with the local Azerbaijani OMON, entered villages in the Shahumyan region and began to forcibly expel their Armenian inhabitants. The operation involved the use of ground troops, armored vehicles and artillery. The deportations of the Armenian civilians was accompanied by allegations of gross human rights violations.
Operation Ring was viewed by many Soviet and Armenian government officials as a heavy-handed attempt by Moscow to intimidate the Armenian populace and forced them to give up their demands for unification. In the end, the operation proved counter-productive, with the violence only reinforcing the belief among Armenians that armed resistance remained the only solution to the conflict. The initial Armenian resistance inspired volunteers to start forming irregular volunteer detachments.
