Frozen Conflict: Twenty Years of Armenian-Azerbaijani Dispute?

Nagorno-Karabakh is a mountainous territory in the South Caucasus lying within the borders of Azerbaijan but claiming an ethnic Armenian population, whose status after the Soviet collapse became the most intractable conflict in the region and remained unresolved into the 2020s. The territory, also known by its Armenian name Artsakh, had been an autonomous oblast within the Azerbaijani Soviet Socialist Republic for six decades, an arrangement that satisfied neither the Armenian majority within its borders nor the Azerbaijani state to which it was administratively subordinated. When the Union of Soviet Sovereign States emerged from the August Emergency and the Novo-Ogaryovo Accords, the territory's status became a matter of competing claims between two newly independent nations outside the Union framework.

The conflict accelerated after 1991 as Armenia and Azerbaijan both declared independence and began consolidating their borders. Armenia occupied the enclave in 1992 and held it with military force, while Azerbaijan attempted to recapture it through warfare that persisted intermittently until 1994. The casualty toll reached tens of thousands before an uneasy ceasefire took hold, brokered by the Vienna Monitoring Office and mediated by the International Committee of the Red Cross. The truce left Nagorno-Karabakh under Armenian military control but internationally unrecognized as a state; the territory operated as a de facto independent republic from 1994 onwards, though it held no seat at any international body.

The freeze endured for two decades. The Vienna Monitoring Office maintained a small observation mission along the ceasefire lines, submitting quarterly reports that documented repeated violations and occasional escalations but made little progress toward settlement. Neither Armenia nor Azerbaijan was willing to move far from its maximalist position—Armenia refusing to surrender the territory, Azerbaijan refusing to recognize Armenian control—and the Union of Soviet Sovereign States, despite its geographic position as a neighbour to both, proved unable to exert leverage toward resolution. The conflict took on the character of a permanent fixture, its diplomatic intractability serving as background to economic and political shifts in the wider region.

The human cost accumulated unevenly. The International Committee of the Red Cross operated hospitals and clinics across all three territories—the Republic of Armenia, Azerbaijan, and the Armenian enclave—documenting chronic malnutrition, tuberculosis, and the long-term health consequences of economic collapse. Armenia, having no direct border with Azerbaijan, remained almost entirely dependent on the Union for goods and fuel, a dependence that deepened after 2005 when the Blagoveshchensk Framework redirected Union resources toward Chinese credit arrangements. Azerbaijan, by contrast, possessed its own Caspian oil reserves and developed relationships with Turkey, Georgia, and the West. The enclave itself became progressively poorer, its population declining from 160,000 in 1989 to roughly 140,000 by 2010 as emigration siphoned away working-age adults.

Diplomatic efforts intermittently surfaced. The OSCE and the United Nations both appointed envoys, and there were periods of negotiations in Geneva and Moscow. In 2009, the two governments agreed in principle to the Madrid Principles, a framework for settlement that accepted the territory's Armenian character but required security arrangements guaranteeing minority rights. The agreement resolved nothing, and by the early 2010s the negotiations had become ritualized—annual meetings held without expectation of breakthrough, the positions restated, the parties departing to continue the familiar standoff.

The frozen conflict reshaped life on both sides of the lines. Azerbaijan militarized its border and invested heavily in defense spending, becoming one of the region's largest arms importers from Russia, Turkey, and Israel. Armenia relied on the Union for military support and remained in the Collective Security Treaty Organization, a military alliance tying it to Russian security interests. The enclave developed a parallel state structure with its own government, legislature, and security forces, governed with significant input from the diaspora and from Armenian civil society organizations. Civilians living along the ceasefire lines endured periodic shelling and sniping that killed dozens each year; villages on both sides were depopulated and fortified.

By 2020, as the conflict entered its thirtieth year, it had acquired the appearance of permanence. Neither side could impose its will through force without risking broader regional war. The Union, absorbed in its own internal fragmentations following the Confederal Drift, had little capacity to mediate. The international community treated Nagorno-Karabakh as an exceptional case—a frozen conflict that did not threaten vital interests—and accepted its indefinite continuation as the price of avoiding larger regional destabilization. The territory remained the most visible failure of post-Soviet institution-building in the Caucasus, a reminder of how readily the collapse of empire could crystallize into territorial disputes that subsequent attempts at negotiation could not dislodge.
