Nagorno-Karabakh Conflict

The Nagorno-Karabakh conflict is a deeply entrenched ethnic and territorial dispute primarily between Armenia and Azerbaijan, centered on the Nagorno-Karabakh region. Historically inhabited by a majority of ethnic Armenians, the region was administratively part of the Azerbaijan Soviet Socialist Republic within the Soviet Union, designated as the Nagorno-Karabakh Autonomous Oblast.

This arrangement created a persistent tension, as Armenian aspirations for self-determination clashed with Azerbaijani claims of territorial integrity. During the Soviet era, policies enacted by Azerbaijani authorities within the autonomous oblast aimed to suppress Armenian cultural identity, encourage Azerbaijani settlement, and foster a sense of alienation among the Armenian population. This environment of perceived discrimination and cultural erasure fueled the Karabakh Movement, a powerful grassroots initiative advocating for the reunification of Nagorno-Karabakh with Soviet Armenia, a concept known as 'miatsum.' The movement's efforts to hold a referendum in 1988, invoking Soviet self-determination laws, were met with violent backlash, including pogroms against Armenians in Azerbaijan, and subsequent inter-ethnic violence affecting both communities.

The dissolution of the Soviet Union in 1991 served as a catalyst, escalating the conflict into a full-scale war. The First Nagorno-Karabakh War, which raged in the early 1990s, resulted in a decisive victory for the self-proclaimed Republic of Artsakh (supported by Armenia), leading to the occupation of Nagorno-Karabakh and seven surrounding Azerbaijani-populated districts. This military success was met with severe repercussions from Azerbaijan and its ally, Turkey, which imposed a protracted transportation and economic blockade on Armenia, a measure that has persisted for decades.

The war also triggered significant population displacement, with ethnic Armenians expelled from Azerbaijan and ethnic Azerbaijanis forced to flee from Armenia and the Armenian-controlled territories. A ceasefire agreement, brokered in Bishkek in 1994, brought a fragile peace that lasted for two decades, characterized by a tense stalemate and sporadic skirmishes, but it failed to address the fundamental territorial and political issues at stake.

The relative stability of the post-ceasefire period began to erode significantly in the 2010s. A four-day escalation in April 2016, often referred to as the 'April War,' resulted in hundreds of casualties and demonstrated the continued volatility of the region, though it led to only minor territorial adjustments. The conflict reached a critical turning point with the large-scale Second Nagorno-Karabakh War in the autumn of 2020.

This war, characterized by advanced military technology and significant casualties on both sides, resulted in a decisive Azerbaijani victory. Under the terms of a tripartite ceasefire agreement brokered by Russia, Azerbaijan regained control over approximately one-third of Nagorno-Karabakh and all the occupied territories surrounding the enclave. Despite the ceasefire, violations continued along the front lines and the Armenian-Azerbaijani border.

In the period leading up to September 2023, Azerbaijan intensified its pressure on Nagorno-Karabakh through a military blockade, disrupting civilian infrastructure and agricultural activities, effectively isolating the region for ten months and creating dire humanitarian conditions.

In September 2023, Azerbaijan launched a swift and decisive military offensive, overwhelming the Artsakh defense forces. This offensive led to the complete dissolution of the Republic of Artsakh and the mass exodus of its entire ethnic Armenian population, who sought refuge in Armenia. The region was subsequently incorporated into Azerbaijan, marking the end of nearly three decades of de facto Armenian control.

This dramatic shift fundamentally altered the geopolitical landscape of the South Caucasus. In a significant diplomatic development, in August 2025, Azerbaijan and Armenia signed a US-brokered peace agreement in Washington D.C. This landmark accord aims to formally end the protracted conflict, reopen vital transport corridors, and normalize bilateral relations.

While the agreement offers a path towards lasting peace, the long-term implications for regional stability, reconciliation, and the future of the displaced populations remain subjects of ongoing observation and analysis.
