The 2020 Nagorno-Karabakh War, often referred to as the Second Nagorno-Karabakh War, was a short but intense conflict primarily fought between Azerbaijan, supported by Turkey, and the Republic of Artsakh (a de facto independent state with an Armenian ethnic majority) and Armenia itself. It largely centred on the disputed Nagorno-Karabakh region and surrounding territories, resulting in a decisive military victory for Azerbaijan and significant territorial changes. This war fundamentally altered the geopolitical landscape of the South Caucasus.
Understanding why the 2020 war broke out requires looking back at decades of unresolved tensions and a simmering frozen conflict. It wasn’t a sudden explosion, but rather the culmination of numerous factors.
A Legacy of Conflict: The First Nagorno-Karabakh War
The First Nagorno-Karabakh War (1988-1994) ended with an Armenian victory. During this conflict, Armenian forces not only gained control of the Nagorno-Karabakh Autonomous Oblast (NKAO) – a region within Azerbaijan that had a majority Armenian population – but also occupied seven surrounding Azerbaijani districts. This created a substantial “buffer zone” and internally displaced hundreds of thousands of Azerbaijanis. For Azerbaijan, this was a national trauma, an occupation of sovereign territory. For Armenians, it was a matter of self-determination and security for the Armenians in Artsakh.
Stalemate and Failed Diplomacy
For nearly three decades, the situation remained largely frozen. The Minsk Group of the OSCE, co-chaired by France, Russia, and the United States, attempted to mediate a peaceful resolution. Their proposals generally involved a phased return of the occupied territories to Azerbaijan in exchange for a determination of Nagorno-Karabakh’s future status. However, these efforts repeatedly stalled. Both sides were entrenched in their positions, unwilling to make the concessions necessary for a lasting peace. Armenia insisted on the right to self-determination for Artsakh, while Azerbaijan demanded the full restoration of its territorial integrity.
Growing Imbalance and Frustration
Over the years, a significant power imbalance emerged. Azerbaijan, with its vast oil and gas revenues, invested heavily in its military, acquiring modern weaponry from various suppliers, including Israel, Russia, and Turkey. Armenia, with a smaller economy and more reliant on Russia for arms, struggled to keep pace. This growing military asymmetry fuelled Azerbaijani confidence and frustration with the diplomatic deadlock. They increasingly viewed a military solution as their only viable option to reclaim lost territory.
Border Clashes and Escalation
Even during the “frozen” period, there were frequent, albeit smaller, skirmishes along the Line of Contact (LoC) separating the forces. These often involved artillery fire and sniper activity, leading to casualties on both sides. Notable escalations included the “Four-Day War” in April 2016, which saw limited territorial gains by Azerbaijan and served as a stark warning of the potential for a larger conflict. These incidents eroded trust and made any diplomatic breakthrough even harder.
Shifting Regional Dynamics
Turkey’s increased involvement in the region also played a crucial role. Under President Erdoğan, Turkey sought to expand its influence in the South Caucasus, forging a closer strategic alliance with Azerbaijan, based on shared Turkic heritage and political interests. This support, including military training and the provision of advanced weaponry (like drones), significantly bolstered Azerbaijan’s capabilities and confidence.
The 44 Days of Conflict: A Swift and Brutal War
The 2020 war, lasting from 27 September to 10 November, was characterised by intense fighting, sophisticated military technology, and significant human and material losses.
Azerbaijan’s Initial Offensive
The conflict began with a large-scale Azerbaijani offensive along the Line of Contact. This was not a border skirmish but a coordinated military operation aimed at reclaiming territory. Azerbaijani forces, utilising a combination of drone strikes, artillery, and ground assaults, quickly targeted Armenian defensive positions.
The Role of Drones and Modern Warfare
One of the defining features of this war was the extensive and highly effective use of unmanned aerial vehicles (UAVs), particularly Turkish-made Bayraktar TB2 drones and Israeli-made loitering munitions (often referred to as “kamikaze drones”). These drones proved devastatingly effective against Armenian armour, artillery, air defence systems, and command-and-control infrastructure. They provided real-time intelligence, precision strike capabilities, and allowed Azerbaijan to maintain air superiority, largely neutralising Armenia’s older, less sophisticated air defences. This marked a significant shift in modern battlefield tactics.
Strategic Objectives and Territorial Gains
Azerbaijan’s strategy focused on a multi-pronged advance, particularly in the southern sector towards the Iranian border, aiming to cut off Artsakh from Armenia proper. They systematically captured villages, towns, and strategic heights. The mountainous terrain made progress difficult, but the continuous drone surveillance and precision strikes allowed Azerbaijani forces to overcome many defensive challenges. Key territorial gains included a significant portion of the occupied Azerbaijani districts surrounding Nagorno-Karabakh and parts of Nagorno-Karabakh itself.
Armenian Resistance and Challenges
Armenian forces, comprising the Artsakh Defence Army and units from the Republic of Armenia, mounted a determined but ultimately outmatched defence. They faced significant challenges:
- Technological Disadvantage: Their older military equipment was vulnerable to Azerbaijani drones and precision artillery.
- Logistics: Supplying forces through the narrow Lachin corridor became increasingly difficult under Azerbaijani fire.
- Manpower: While highly motivated, the smaller population of Armenia and Artsakh meant they had fewer reserves compared to Azerbaijan.
- Lack of Air Cover: The absence of effective air defence and air support left ground troops exposed.
Civilian Impact and Allegations of War Crimes
The conflict had a severe impact on civilians. Both sides reported civilian casualties and damage to infrastructure, including homes, schools, and cultural sites. There were numerous allegations of war crimes, including the targeting of civilian areas, the use of banned munitions, and the mistreatment of prisoners of war. International human rights organisations called for investigations into these alleged violations.
The Ceasefire Agreement and its Immediate Aftermath
The war concluded abruptly with a Russian-brokered ceasefire agreement, significantly reshaping the political and territorial landscape.
Russia’s Intervention and the Peace Deal
As Azerbaijani forces advanced on Shusha (known as Shushi to Armenians), a strategically vital city within Nagorno-Karabakh, and with the imminent collapse of Armenian defences, Russia stepped in decisively. On 9 November 2020, a trilateral ceasefire agreement was signed by Armenia’s Prime Minister Nikol Pashinyan, Azerbaijan’s President Ilham Aliyev, and Russia’s President Vladimir Putin.
The key provisions of the agreement were:
- Cessation of Hostilities: An immediate end to all fighting.
- Territorial Handover: Armenia agreed to withdraw from the remaining occupied Azerbaijani districts surrounding Nagorno-Karabakh (Agdam, Kalbajar, and Lachin) by specific dates.
- Russian Peacekeepers: A contingent of approximately 2,000 Russian peacekeepers was deployed to monitor the ceasefire, particularly along the new Line of Contact and the Lachin corridor.
- Lachin Corridor: A narrow strip of land linking Armenia to Nagorno-Karabakh was to remain open, secured by Russian peacekeepers.
- Return of Refugees: Internally displaced persons and refugees were to return to their homes under the supervision of the UNHCR.
- Opening of Communications: All economic and transport links in the region were to be unblocked, including a new transport route through Armenia connecting Azerbaijan’s Nakhchivan exclave to mainland Azerbaijan.
Shifting Control and Displaced Populations
The agreement formalised Azerbaijan’s significant territorial gains, reversing nearly 30 years of Armenian control over the surrounding districts. Many Armenians living in these areas were forced to leave their homes, often engaging in scorched-earth tactics as they departed, burning houses and felling trees. Conversely, Azerbaijanis displaced by the first war began to plan their return to areas now under Azerbaijani control.
Russia’s Renewed Influence
The ceasefire agreement underscored Russia’s enduring influence as the primary power broker in the South Caucasus. By deploying peacekeepers, Russia solidified its military presence and became an indispensable guarantor of the new status quo, albeit one that many viewed as leaning heavily towards Azerbaijani interests.
Long-Term Implications and Ongoing Challenges
The 2020 war did not bring a lasting peace; rather, it ushered in a new, albeit fragile, geopolitical reality with numerous unresolved issues.
The Status of Nagorno-Karabakh
While the agreement defined new borders, the ultimate status of Nagorno-Karabakh itself remained unaddressed. A portion of the historical Nagorno-Karabakh region, including its capital Stepanakert (Khankendi to Azerbaijanis), remained under the control of the de facto Artsakh Republic, protected by Russian peacekeepers. This continues to be a flashpoint. Azerbaijan considers the entire region its sovereign territory and insists that Armenians living there must accept Azerbaijani citizenship. Armenians in Artsakh continue to seek self-determination, fearing for their safety and cultural identity under Azerbaijani rule.
Border Demarcation and Delimitation
The 2020 war created new, often undefined, borders between Armenia and Azerbaijan. The process of demarcating and delimiting these borders has been fraught with tension, leading to frequent incursions and skirmishes, particularly in areas like Syunik province in Armenia. These incidents often escalate, causing further instability.
Regional Geopolitics and External Actors
The war significantly altered regional power dynamics:
- Turkey’s Growing Role: Turkey cemented its position as a key regional player and a close ally of Azerbaijan, challenging Russia’s traditional dominance.
- Russia’s Balancing Act: Russia continues to maintain relations with both Armenia and Azerbaijan, acting as a security guarantor for the former and a key economic partner for the latter, while also overseeing the peacekeepers.
- Iran’s Concerns: Iran, bordering both Armenia and Azerbaijan, watched the conflict closely, particularly concerned about any changes that might empower a pan-Turkic agenda or threaten its own border security and trade routes.
- Western Disengagement: The European Union and the United States were largely on the sidelines during the conflict and in the immediate aftermath, highlighting their limited influence in crisis resolution in the region.
Humanitarian and Reconciliation Challenges
Tens of thousands of people were displaced by the conflict, and significant infrastructure was damaged. The process of rebuilding, de-mining, and facilitating the safe return of displaced persons is immense. Beyond the practicalities, there is a deep need for reconciliation, which remains a distant prospect given the deeply rooted historical grievances, trauma, and continued inflammatory rhetoric from both sides. Prisoner exchanges and the investigation of alleged war crimes remain contentious issues.
Economic Implications
The unblocking of transport corridors, particularly the proposed “Zangezur corridor” (connecting Nakhchivan to mainland Azerbaijan through Armenian territory), has significant economic implications for the region. While it could open new trade routes and foster economic development, its implementation is highly sensitive and complex, requiring careful negotiation and trust-building between the parties.
In conclusion, the 2020 Nagorno-Karabakh War was a watershed moment, decisively shifting the military and political balance in the South Caucasus. While a ceasefire is in place, the underlying causes of the conflict remain largely unresolved, leaving the region in a state of fragile peace, prone to renewed hostilities unless a comprehensive and equitable political solution can be found.
