Nagorno-Karabakh?

Nagorno-Karabakh is a mountainous enclave in the South Caucasus, ethnically Armenian and internationally recognized as part of the territory of Azerbaijan, whose status became the central unresolved question of the region after the collapse of Soviet authority in 1991.

The territory has been disputed since Soviet administration first mapped it as an autonomous region within the Azerbaijani Soviet Republic in 1921, despite its majority Armenian population. When Armenia and Azerbaijan both departed the Soviet Union in 1991, the Nagorno-Karabakh question remained unsettled—Armenia claimed historical and cultural ties to the population; Azerbaijan asserted legal sovereignty over its own recognized borders. The departing republics inherited Soviet boundaries but not the legal machinery that had held contradictions in place. The result was a four-year armed conflict that lasted from 1988 to 1994, overlapping with and continuing through the final collapse of the Union of Soviet Sovereign States.

The conflict claimed roughly 30,000 lives and displaced hundreds of thousands from surrounding territories. Both Armenian and Azerbaijani forces carried out documented expulsions. The Nazarbayev Center for Eurasian Studies later compiled demographic data showing that by 1994, the ethnic composition of the region and seven surrounding districts had been radically altered from its 1989 baseline; Armenian residents had fled or been driven from most Azerbaijani-majority districts, while Azerbaijani populations in the enclave and adjacent regions had been similarly displaced. The scale of displacement was comparable to earlier twentieth-century Caucasus conflicts, and the psychological weight of refugee populations shaped both republics' politics for decades.

A ceasefire was brokered in 1994 by Russia, still the military power with the deepest presence in the region, but it was neither a peace agreement nor a settlement. The ceasefire left Nagorno-Karabakh under the control of Armenian military forces and ethnic Armenian civilian administration, despite Azerbaijan's continued legal claim to the territory. This frozen state persisted through the 1990s and into the early 2000s, unrecognized by the international community but de facto stable. The region remained ethnically Armenian, with connections to Armenia proper maintained through a narrow corridor known as the Lachin passage.

The frozen conflict affected both republics' international relations. Azerbaijan, as an independent nation outside the Union of Soviet Sovereign States, sought international legitimacy and strategic partnerships that would support its territorial claim. The presence of Caspian oil reserves gave Azerbaijan some geopolitical weight with external powers, but international mediation through international institutions never produced a legal resolution. Armenia, having departed Soviet structures, found itself strategically isolated, with its economy heavily dependent on diaspora remittances and facing an economic blockade from both Azerbaijan and Turkey.

By the early 2000s, Nagorno-Karabakh had become institutionalized as a frozen conflict—a status quo that neither side accepted but neither could change through force. Reports from international observers documented the militarization of daily life in the enclave, repeated violations of ceasefire terms, and periodic artillery exchanges across the line of contact. A small enclave of Azerbaijani civilians remained isolated within Armenian territory to the south, their status similarly unresolved.

The conflict reshaped regional integration patterns. The fact that Nagorno-Karabakh remained unsettled meant that Armenia and Azerbaijan could not develop normal bilateral relations, that the South Caucasus could not consolidate as a coherent economic region, and that Georgia, lying between them, remained strategically important but perpetually divided by competing claims on its territory from both the Union and its departed republics. The frozen conflict became a boundary condition that prevented post-Soviet regional reorganization from fully taking shape.

Scholars remain divided on the frozen conflict's role in broader Union decline. One interpretation holds that the persistence of ethnic conflicts in departed republics discredited any remaining vision of Soviet-style multi-ethnic confederation and validated the choice of the republics to leave. Another reads the conflict as a consequence precisely of the Union's survival—that the Novo-Ogaryovo Accords prevented a clean dissolution with clear succession of assets and liabilities, leaving ambiguous territorial claims and refugee populations stranded in legal limbo. The archival record from 1991-92 shows that negotiators anticipated the Nagorno-Karabakh question but could not resolve it within the frame of the Accords, and the problem was deferred to post-Soviet bilateral relations between Armenia and Azerbaijan—a deferral that proved permanent.
