The six-week war in Nagorno-Karabakh lasted from September 27 to November 10, 2020. Exact losses remain unknown, but several thousand combatants were reportedly killed on both sides. Hundreds of civilians are believed to have died in the fighting, as well.
Earlier this month, the Armenian Army suffered heavy losses in southern Nagorno-Karabakh. By November 7, Azerbaijani troops seized control of Shusha, a strategically vital city located more than 1,600 feet above and just nine miles south of Stepanakert, Karabakh’s unofficial capital. Shusha also had enormous symbolic value for Karabakh’s separatists (read more about this by clicking on the map below).
Just as it captured Shusha, the Azerbaijani military also cut off the main road to the west that connects Armenia to Karabakh. Armenian Prime Minister Nikol Pashinyan says it became clear after these events that his people risked losing the entire Karabakh territory. As a result, Pashinyan agreed to what he describes as a “painful” settlement with Azerbaijan, brokered by Russian President Vladimir Putin.
In exchange for permitting the continued existence of a compact Armenian Karabakh (without formal status, guarded by Russian peacekeepers), Azerbaijan effectively gained territory in Armenia itself, winning a transportation corridor from the mainland to its western exclave, the Nakhchivan Autonomous Republic, which has a small shared border with Baku’s close ally, Turkey. Border guards from Russia’s Federal Security Service will protect the corridor through Armenia.

Karabakh separatists seized the Agdam District in the summer of 1993, capturing significant ammunition supplies and military hardware abandoned by the Azerbaijani Army. After November 20, 2020, when the Agdam District is returned to Azerbaijani control, Russian peacekeepers will likely redeploy to the west.
The breakaway Nagorno-Karabakh’s capital city is named after Stepan Shaumian, a prominent Bolshevik revolutionary in the Caucasus whom Baku blames for mass murdering ethnic Azeris during the Russian Civil War. Azerbaijan calls the city Khankendi, meaning “village of the khan.” Following the November 2020 truce, the city will be within the Azerbaijani military’s artillery range. An estimated 50,000 people still live here.
The city of Shusha (known to Armenians as Shushi) plays an important role in the historical memories of both peoples. Shusha was the capital of the Turkic Karabakh Khanate in the 17th and 18th centuries. In March 1920, during an earlier war between Armenia and Azerbaijan, Azerbaijani troops captured the city and killed several hundred, perhaps several thousand, local Armenians. In 1992, soldiers from the self-declared Nagorno-Karabakh Republic seized Shusha and expelled its ethnic Azerbaijanis, who by then comprised a majority of the city’s population. In November 2020, Azerbaijan retook it.
Russia has pledged 1,960 soldiers with small arms, 90 armored personnel carriers, and 380 vehicles and other special equipment. After November 20, 2020, when the Agdam District is returned to Azerbaijani control, Russian peacekeepers will likely redeploy to the west.
This mountain pass has been Armenia’s key route to the Karabakh region since Armenian troops seized the city of Lachin in 1992. Under the November 2020 settlement, the corridor will be demilitarized and monitored by Russian peacekeepers.
The Kalbajar District was one of the last areas captured by Armenian forces during the Karabakh war in the early 1990s. These gains granted the breakaway Karabakh Republic a long contiguous border with Armenia, where a mountain road was constructed to supplement the Lachin Corridor.
The exact route of the corridor from the Azerbaijani mainland to the Nakhchivan Autonomous Republic remains unclear. The pathway is strategically significant for Baku, as it connects the Azerbaijani mainland to its western exclave. For the past 30 years, access to the region has been limited to air travel or border crossings from Iran and Turkey. Border guards from Russia’s Federal Protective Service will monitor this corridor.
There were armed clashes in this area during the Russian Civil War following the Bolsheviks’ rise to power. After the war, the Bolsheviks joined the region with the Azerbaijan SSR. For Azerbaijani President Ilham Aliyev’s family, the autonomous republic carries special symbolic value: Aliyev’s father, Heydar Aliyev (who established Azerbaijan’s modern-day police state), was born in Nakhchivan and revived his political career there, after the USSR’s collapse.
Defeat on the battlefield and losses imposed under the settlement make it unclear how the unrecognized Nagorno-Karabakh Republic’s state administration will continue to function as it has for the past quarter-century. The trilateral agreement says nothing about sustaining or terminating the administration’s operations, and Yerevan will find it far more difficult to support Karabakh’s local government now that the region has been separated from Armenia.
For the same reasons, the future of the Karabakh Army remains in doubt, given that Armenia will now find it far harder to transfer military hardware through territory under Azerbaijan’s political control (albeit fenced off by Russian peacekeepers).
Under the November 2020 settlement, the region’s territorial demarcations have returned almost exactly to what they were in 1991. Thirty years ago, ethnic Azerbaijanis constituted the majority of the population in the areas around the Karabakh Autonomous Region (including in Shusha) that are now returning to Baku’s control. The new trilateral agreement allows these individuals to return to the homes they had to abandon, but the fate of the ethnic Armenians who since settled these towns is unresolved. Even the Armenians within the unrecognized Karabakh Republic’s boundaries could be pressured to leave.
During the six-week war, many people living in the breakaway Karabakh Republic fled to Armenia. Even with Russian peacekeepers on the ground, returning home won’t appeal to everyone. As in 1991, there are again Azerbaijani artillery guns deployed in the hills above Stepanakert, just a few miles from the city’s residential neighborhoods. The region’s lifeline to Armenia has been cut off, and nobody knows if Russian soldiers will still be around in five years to protect the population from another Azerbaijani assault. In the face of these dangers and uncertainties, a significant number of Armenian refugees may stay away, despite the formal assurances offered in the November settlement.
The war has endangered sites like the Dadivank monastery and the ruins of Tigranakert, located in districts of Karabakh that will now return to Azerbaijani control. Armenians recognize these places as important remnants of their ancient heritage and worry that Baku might destroy this evidence of Armenian culture’s long history (just as satellite photos suggest Azerbaijan destroyed an ancient Armenian cemetery in Nakhchivan). On the other hand, the leadership in Baku has denied such plans and long argued (however questionably) that its ancestors among the Caucasian Albanians were, in fact, responsible for landmarks like the Dadivank monastery.
In 4.5 years, Azerbaijan will be able to demand the withdrawal of Russian peacekeepers, allowing it to resume its stated aim in the region: “a final solution to the Karabakh issue.” (Yerevan and Moscow will also have the right to end the peacekeeping deal, but it’s unlikely that either state would seek to unfreeze the conflict in the foreseeable future.)
There are some indications that Azerbaijan plans to stick with the settlement and Russia’s peacekeepers for more than five years, too. President Aliyev says he personally insisted on the ground corridor to Nakhchivan — something the Azerbaijani mainland hasn’t had for 30 years. The construction of a new road through the Lachin Corridor, meanwhile, also suggests planning on a time horizon well beyond five years. The new passageway will bypass Shusha, unlike the current road that runs along the city’s outskirts.
Political expediency, however, might override any economic incentives for maintaining the new status quo. The settlement’s meaning and implementation now rely chiefly on how the truce is interpreted by three men: Vladimir Putin, Ilham Aliyev, and Turkish President Recep Erdoğan (who apparently played an active role in the ceasefire negotiations). In the next five years, these leaders could change their minds about the Karabakh resolution. Before 2025, some of these men could even lose power.
By openly aiding Azerbaijan and achieving a joint victory, Turkey has strengthened its influence in the Caucasus and throughout the “Turkic world,” proving itself to be a decisive, effective ally. Some military experts have also pointed out that Ankara’s intervention demonstrated the feasibility of successfully “unfreezing” an old conflict using modern weaponry and tactics, which could have profound repercussions across the former Soviet Union, where dormant hostilities abound.
The implications of the six-week war pose a threat to Russia’s foreign policy in its “near abroad,” where the Kremlin has gained tools of coercion by intervening to freeze conflicts in exchange for military bases and peacekeeping zones.
On the other hand, however, freezing a conflict and deploying peacekeepers is exactly what Moscow has achieved in Nagorno-Karabakh with the November 2020 settlement.
Other political analysts argue that Russia and Turkey both made gains in the Karabakh War, acting more as allies than adversaries. In other words, the six-day war was part of a joint project by Moscow and Ankara to overhaul the Middle East, Northern Africa, and the Caucasus. Yes, there’s still rivalry here (in both Syria and Libya, Russia and Turkey have repeatedly found themselves on opposite sides), but Putin and Erdoğan have operated most effectively when they agree on spheres of influence and cooperate to squeeze out other would-be players, whether it’s Iran, the European Union, or the United States.
