Azerbaijan’s conflict history begins with its 1920 incorporation into the Soviet Union, which submerged an emerging national identity and left the mostly Armenian-populated Nagorno-Karabakh region administered as an autonomous oblast inside Soviet Azerbaijan. The central process shaping modern Azerbaijan was the Nagorno-Karabakh conflict: as Soviet rule weakened after 1988, Armenian and Azerbaijani nationalism collided over the enclave, and a war following independence in 1991 left Armenia and local separatists in control of the territory and seven surrounding districts by 1994. Azerbaijan’s greatest regional influence followed directly from that loss: its oil-funded rearmament under the Aliyev family reversed the military balance, and the 2020 war and 2023 offensive restored Baku’s control and triggered the exodus of Nagorno-Karabakh’s Armenian population. That victory exposed the legacy’s limits: a state built around reclaiming lost territory now confronts the harder task of governing durable peace with Armenia and reintegrating a depopulated region.
In 2025, UCDP recorded no conflict-related deaths in Azerbaijan: no wars, no fighting between armed groups, and no organized attacks on civilians.
The World Map of Conflict uses two complementary datasets from the Uppsala Conflict Data Program (UCDP) to visualise conflict per country.
The colour coding of the overview base map is derived from the UCDP Georeferenced Event Dataset (GED), which contains fully verified conflict data aggregated at the country level. UCDP publishes the GED annually (typically May–June of the following year) to allow careful validation of every recorded event.
The map on this country page draws from the UCDP Candidate Events Dataset (CED), which includes the most recent reported events and provides a near-real-time overview of conflict developments. Because these events are still under verification, the data should be considered preliminary.
Historical Lenses
To understand Azerbaijan’s conflict history, it is first important to understand what kind of country it is. Historians often explain the same country in different ways depending on what they believe are the main forces driving history. Each historical lens below offers a different, evidence-based interpretation of the country’s development.
The interpretation most widely accepted by historians, based on mainstream historical research and university scholarship. It reflects broad areas of agreement while acknowledging where historians disagree.
Azerbaijan sits on the western shore of the Caspian Sea, in the South Caucasus, where the Greater Caucasus mountains taper down toward a lowland threaded by the Kura and Aras rivers before both empty near the Caspian coast. To its north lies Russia’s North Caucasus, to the west Georgia and Armenia, to the south Iran, with which Azerbaijan shares both a long border and a modern national name, since millions of ethnic Azerbaijanis live across that border in Iranian Azerbaijan. Most of the roughly ten million people who live within the country’s borders are ethnic Azerbaijanis, a Turkic-speaking people, and the great majority are Muslim, with a Shia Muslim majority unusual for a Turkic nation. The mainstream scholarly account, most fully set out by Svante Cornell, treats Azerbaijan as a state whose modern identity was assembled in stages: a Persianate and Turkic pre-modern past, absorption into the Russian and then Soviet empires, a brief flash of independence in 1918-1920, seven decades inside the USSR, and a second independence in 1991 that arrived alongside a war it did not choose. Consensus scholarship reads this layered inheritance — Turkic language, Shia faith, Persian cultural gravity, Russian and Soviet administrative habits — as producing a state comfortable holding several identities at once rather than insisting on a single, purified one.
Svante E. Cornell, Azerbaijan Since Independence (2011); Thomas de Waal, Black Garden: Armenia and Azerbaijan through Peace and War (2003).
Mainstream historians mark several thresholds. The Russian conquest of the Caucasus, completed by 1828 treaties that split historic Azerbaijani lands between the Russian and Persian empires, first fixed the border with Iran and set Baku on a trajectory away from Tehran and toward St. Petersburg. The Baku oil boom of the 1870s-1900s, which briefly made the city the source of roughly half the world’s petroleum, built an industrial working class and a cosmopolitan elite — and with them, by 1918, the short-lived Azerbaijan Democratic Republic, the first secular parliamentary republic in the Muslim world, snuffed out by the Red Army in 1920. Soviet rule, formally begun that year, imposed rapid industrialization, land collectivization, and a nationalities policy that both created a codified Azerbaijani nation on paper and drew the internal border that placed the Armenian-majority Nagorno-Karabakh region inside Soviet Azerbaijan in 1923 — a decision consensus scholarship treats as the single most consequential administrative act in the country’s twentieth century. The Soviet collapse in 1991 delivered independence and, simultaneously, a losing war over that same territory. The final threshold, the 2020 war and the September 2023 offensive that returned all of Nagorno-Karabakh to Azerbaijani control, closed a thirty-year wound but reopened the harder question of what peace with Armenia now requires.
Svante E. Cornell, Azerbaijan Since Independence (2011); Thomas de Waal, Black Garden (2003).
In the consensus account, the Azerbaijani nation and the Azerbaijani state did not arrive together. A distinct Azerbaijani Turkic identity had been forming for centuries under Persian and then Russian rule, sharpened in the late nineteenth century by a Baku-based intelligentsia that mixed Islamic reform, Turkic cultural revival, and European socialist ideas. Statehood, however, arrived abruptly in 1918, improvised by politicians in the wreckage of the Russian and Ottoman empires rather than won through a long national movement, and it lasted barely two years before Soviet conquest. Soviet nation-building then did something paradoxical: it suppressed independent political life while simultaneously codifying “Azerbaijani” as an official nationality with its own titular republic, language policy, and administrative boundaries, manufacturing many of the institutional building blocks a fully sovereign state would later need. When independence returned in 1991, it came not as the culmination of a mass national movement but as a by-product of the Soviet Union’s own dissolution, handing the new Azerbaijani leadership — first nationalist reformers, then Heydar Aliyev’s return to power in 1993 — a state whose institutions were largely inherited from Moscow. Scholars therefore describe modern Azerbaijan’s formation as state-first: statehood, lost and regained twice by external upheaval, and nationhood built up around it only gradually.
Svante E. Cornell, Azerbaijan Since Independence (2011).
Consensus scholarship treats the transformation of oil into state power as the process that best explains Azerbaijan across its modern history. Baku’s late-nineteenth-century oil boom created the country’s first industrial economy and its first cosmopolitan elite; the same resource then financed, after 1994’s so-called “Contract of the Century” with Western oil majors, the reconstruction of a state battered by the loss of Nagorno-Karabakh. Rising energy revenue channelled through the state oil company, SOCAR, gave Heydar Aliyev and then his son Ilham Aliyev the fiscal independence to build a centralized presidential system with limited need for either Western aid or domestic economic pluralism, and after the mid-2000s it funded the military rearmament that reversed the 1990s territorial losses in 2020 and 2023. The Baku-Tbilisi-Ceyhan pipeline, completed in 2006, extended that logic geopolitically, giving Azerbaijan an export route to world markets that bypassed both Russia and Iran and made the country a partner Western governments courted despite its authoritarian turn. Historians see this as a single continuous thread: oil wealth has repeatedly allowed Azerbaijan’s rulers to convert an underground resource into overground authority, financing everything from the country’s first modern institutions to its most recent war.

Alternative interpretations developed by respected historians that challenge or expand the mainstream view. These perspectives highlight debates within historical scholarship rather than presenting a single accepted explanation.
The revisionist account keeps the same map — a Caspian-facing state wedged between Russia, Georgia, Armenia, and Iran, with a Shia Turkic majority of roughly ten million — but disputes how “natural” that map and that majority actually are. Where the consensus reading treats Azerbaijan’s borders and its Nagorno-Karabakh problem as an inheritance from ancient settlement patterns colliding with modern nationalism, revisionist historians led by Arsène Saparov argue that many of the ethnic-territorial “facts” now taken as bedrock were themselves manufactured by Soviet administrators in the 1920s, who drew internal republic and autonomous-region boundaries not to reflect settlement but to manage rival nationalist claims and keep neighbouring republics dependent on Moscow for arbitration. On this reading, Azerbaijan is less a nation that simply found its natural borders than a Soviet administrative artifact whose population was then taught, over seventy years of nation-building, to regard those artificial lines as ancestral. The counter-weight mainstream historians raise is real: Azerbaijani Turkic settlement of the Kura-Aras lowlands long predates the Soviet Union, so revisionists are reweighting how much of the current territorial dispute is inherited versus engineered, not inventing the population’s presence from nothing.
Arsène Saparov, From Conflict to Autonomy in the Caucasus (2014) — a genuinely contested academic thesis, presented here as a challenge rather than settled fact.
Revisionist scholarship reweights the same thresholds around a single decision: the 1921-1923 Bolshevik boundary-drawing that placed Nagorno-Karabakh, an Armenian-majority highland, inside the new Azerbaijan SSR as an autonomous oblast rather than transferring it to Soviet Armenia. Saparov’s archival work argues this was not, as older nationalist historiographies on both sides claimed, a deliberate reward or punishment handed to one nation over the other, but the product of shifting, improvised Bolshevik calculations — about a possible revolution in Turkey, about pacifying local elites, about administrative convenience — that hardened into permanent borders almost by accident. Later thresholds, in this reading, are downstream of that improvisation: the 1988-1994 war was fought over a boundary neither side had originally chosen so much as inherited from a bureaucratic process neither fully controlled, and the 2020-2023 recovery of the territory settled a dispute whose origins were more procedural than primordial. This unsettles the standard chronology’s implication that the conflict expressed some ancient, near-inevitable rivalry; the counter-weight is that once the Soviet boundary existed, seventy years of lived experience, migration, and grievance on both sides gave it a reality no amount of pointing to its bureaucratic origins can simply dissolve.
Arsène Saparov, From Conflict to Autonomy in the Caucasus (2014).
Where the mainstream account treats Azerbaijan’s Shia-majority, secular, Turkic identity as a stable cultural inheritance, revisionist scholars argue that “Azerbaijani” as a religious-national category was itself substantially a Soviet-era construction layered onto a population that, before the twentieth century, more often described itself by locality, tribe, or simply as Muslim Turks of the Caucasus and Iranian Azerbaijan alike, without a firm border between the two. Soviet nationality policy, in this account, needed a codified “Azerbaijani” nation to justify the Azerbaijan SSR’s existence, and so it promoted a standardized Azerbaijani-Turkic language and literary canon while deliberately playing down the population’s confessional and cross-border ties to Shia Iran, since a religiously assertive, Iran-facing identity would have been harder for an atheist state to sponsor. The strict secularism modern Azerbaijan practises — including restrictions on Islamic political organizing that mainstream accounts describe simply as caution about Iranian influence — is read by revisionists as the direct institutional afterlife of that Soviet-era suppression, not a spontaneous local preference. The counter-weight: Azerbaijani distinctiveness from Iranian Azerbaijan and from Persian-speaking Shia culture had genuine pre-Soviet roots in language and in a nineteenth-century Baku intelligentsia’s own choices, so revisionists are arguing about how much Soviet engineering hardened an identity rather than claiming it invented one from nothing.
Arsène Saparov, From Conflict to Autonomy in the Caucasus (2014); Ayça Ergun, “Secularism and National Identity in Post-Soviet Azerbaijan,” Journal of Church and State 62(3) (2020).
Instead of treating oil-funded state power as the engine of Azerbaijani history, revisionist scholarship names Soviet administrative engineering — the drawing and redrawing of internal borders, nationality categories, and elite hierarchies between the 1920s and 1930s — as the process that most durably shaped the country. On this reading, the oil boom mattered, but its economic logic was itself channelled through boundaries and institutions Soviet planners had already fixed; Baku’s oil wealth built Soviet Azerbaijan’s industrial base only because Moscow had first decided where “Azerbaijan” began and ended and who its ruling class would be, including elevating Heydar Aliyev through the Soviet security apparatus decades before he became independent Azerbaijan’s president. The Nagorno-Karabakh dispute, the single conflict that has dominated Azerbaijan’s post-Soviet existence, is on this account less a resource story than a border-engineering story finally working itself out by force once Moscow’s arbitrating hand was removed in 1991. The counter-weight mainstream historians offer is that oil revenue, not administrative inheritance, explains why Azerbaijan specifically — rather than similarly Soviet-engineered neighbours — was able to rearm and win in 2020 and 2023; revisionists answer that the capacity to convert oil into an army still ran through Soviet-built institutions and elite networks, so the two processes are entangled rather than competing explanations.
Arsène Saparov, From Conflict to Autonomy in the Caucasus (2014).
Explains history through religion, culture, identity, political traditions, ideology and the stories societies tell about themselves. This lens asks how beliefs and shared identities have shaped historical development.
Seen through identity and belief, Azerbaijan is a Caspian nation of roughly ten million people whose Turkic language and Shia Muslim majority — a combination found almost nowhere else outside Iran — sit inside a state that has, since 1991, insisted just as firmly on secularism as on faith. Baku, the capital and by far the largest city, has long styled itself a cosmopolitan meeting point of Persian, Turkic, Russian, and European influence rather than a provincial religious centre, and that self-image runs through how Azerbaijanis narrate their own culture: a nineteenth-century oil-boom elite that patronized theatre, opera, and a modernizing press; a 1918 republic that gave women the vote before many European states did; and a Soviet period that, whatever else it suppressed, entrenched a genuinely secular public culture that survived the USSR’s collapse. Politically, the country has been governed since 1993 by the Aliyev family, first Heydar and then his son Ilham, whose rule blends nationalist appeals to the Nagorno-Karabakh cause with a patronage-based, oil-financed state that tolerates little organized opposition. Cultural and political identity in Azerbaijan are, in this lens, inseparable: the same secular, Turkic, Shia-but-not-Islamist self-image that distinguishes Azerbaijan from both Iran and its more religiously assertive neighbours is also the identity the ruling family invokes to justify its own continuity in power.
Suha Bolukbasi, Azerbaijan: A Political History (2011); Ayça Ergun, “Secularism and National Identity in Post-Soviet Azerbaijan,” Journal of Church and State 62(3) (2020).
This lens marks its thresholds in shifts of belief and authority rather than territory alone. The nineteenth-century Baku intelligentsia’s turn toward Turkic cultural revival and Islamic modernism, epitomized by reformist journals and, in 1918, a republic that separated religion from state business, first set Azerbaijani political culture on a secular, Turkic-nationalist path rather than a religious one. Soviet rule after 1920 pushed that separation to an extreme, closing mosques, suppressing clergy, and replacing religious authority with Communist Party structures, so thoroughly that by the time the USSR collapsed in 1991, Shia identity in Azerbaijan had become more a marker of heritage than a source of active political mobilization — a sharp contrast with revolutionary Iran next door. Heydar Aliyev’s return to power in 1993, engineered through his Soviet-era security and Communist Party networks rather than through religious or purely nationalist credentials, then fused that secular political culture with a new personalist authority, a fusion his son Ilham inherited unchanged in 2003. The final threshold, the 2020 and 2023 military victories over Armenia, gave the Aliyev government a wave of genuine popular legitimacy built on national rather than religious symbolism, further entrenching secular Azerbaijani nationalism, not Shia identity, as the state’s primary claim on its citizens’ loyalty.
Suha Bolukbasi, Azerbaijan: A Political History (2011).
In this lens, Azerbaijani nationhood was assembled from culture and religion working against, not with, each other. A shared Shia faith with Iran might have supplied one basis for solidarity, and a shared Turkic language and Ottoman-adjacent culture might have supplied another pointing toward Turkey, but Azerbaijani identity-builders — from the 1918 republic’s founders through the Soviet nationality architects to today’s government — have consistently defined the nation by insisting on distance from both, cultivating a specifically Azerbaijani, secular, Turkic-but-not-pan-Turkist, Shia-but-not-Iranian identity instead. The state came first here too, but for cultural rather than purely administrative reasons: Soviet Azerbaijan needed its own literary language, its own historical narrative, and its own approved culture heroes distinct from both Ottoman Turkish and Persian traditions, and those official cultural products then became, after 1991, raw material for a genuinely popular Azerbaijani national identity rather than merely propaganda. The relationship between state and nation is therefore top-down but self-reinforcing: political authority, from the Soviet Communist Party to the Aliyev presidency, has repeatedly defined what “Azerbaijani” culture and religion mean in public life, and the population has, over successive generations, come to inhabit that definition as genuinely its own rather than as an imposition.
Suha Bolukbasi, Azerbaijan: A Political History (2011).
The process this lens names as central is the deliberate construction and defence of a secular Azerbaijani identity positioned between two more assertive neighbours, Shia Iran and Turkic, historically pan-Turkist-leaning Turkey. From the 1918 republic’s separation of mosque and state, through Soviet-enforced secularism, to the modern government’s wariness of independent Islamic political organizing, Azerbaijani authorities have repeatedly treated too-close an identification with either neighbour as a domestic political threat rather than a natural affinity, and have used cultural policy, media, and periodic crackdowns on religious groups to keep the Shia-Turkic combination read as uniquely, safely Azerbaijani rather than as a lever either Tehran or Ankara could pull. The Nagorno-Karabakh conflict fits this process rather than standing apart from it: the government has consistently framed the war and its 2020-2023 resolution in national and territorial terms, not religious ones, even though the opposing population was predominantly Christian Armenian, because a religious framing would sit awkwardly with the secular self-image the state has spent a century building. Historians working in this lens argue that this managed, defensive secularism — not oil, and not any single conflict — is the through-line that best explains why Azerbaijan’s politics look the way they do.

Explains history through geography, natural resources, trade, demographics, technology and economic structures. This lens explores how the physical environment and material conditions have influenced historical change.
Geography gives Azerbaijan two defining facts: it sits directly on the Caspian Sea, which holds some of the world’s oldest and richest oil and gas fields, and it occupies a narrow land corridor in the South Caucasus that any power wanting to move goods, pipelines, or armies between the Black Sea, the Caspian, Russia, Iran, and Turkey has to cross or route around. Baku’s harbour and the surrounding Absheron Peninsula sit atop oil-bearing strata so close to the surface that natural seepages and burning gas vents were recorded by travelers for centuries before industrial drilling began there in the 1840s, among the earliest anywhere in the world. That combination — a resource-rich coastline attached to a geopolitical chokepoint — has shaped a population of roughly ten million concentrated disproportionately around Baku, where oil-era jobs, infrastructure, and now government spending are heaviest, leaving much of the rural south and west comparatively underdeveloped. Economic and geographic historians therefore read Azerbaijan less as a culturally defined nation that happens to have oil than as a resource-and-transit territory whose modern population, capital city, and infrastructure were built specifically around extracting and moving what lies beneath its own soil and shipping it to everyone else.
Oksan Bayulgen, Foreign Investment and Political Regimes: The Oil Sector in Azerbaijan, Russia, and Norway (2010).
This lens’s thresholds are extraction booms and the transit routes built around them. The first Baku oil boom, from the 1870s through the 1900s, briefly made the city the source of roughly half the world’s petroleum output, pulling in Russian, Armenian, and European capital and creating, almost overnight, one of the Russian Empire’s most industrialized, multi-ethnic cities — a boom that also seeded the later ethnic tensions the Soviet era would inherit. Soviet-era central planning then redirected Baku’s oil industry toward supplying the USSR’s internal market rather than world export, a redirection that, combined with wartime destruction and the rise of Siberian fields, left Azerbaijan’s oil sector visibly aged by the 1980s. Independence in 1991 reopened the country to world markets, and the 1994 “Contract of the Century” with a Western oil consortium marked the second great threshold, bringing in the capital and technology to develop deep-water Caspian fields. The completion of the Baku-Tbilisi-Ceyhan pipeline in 2006, routing Caspian oil to the Mediterranean while bypassing both Russia and Iran, was the threshold that converted Azerbaijan from an oil producer into a geopolitical transit state, and post-2020 discussions of a Zangezur transport corridor through Armenian territory show the same logic still shaping the country’s ambitions today.
Oksan Bayulgen, Foreign Investment and Political Regimes (2010); Steve LeVine, The Oil and the Glory: The Pursuit of Empire and Fortune on the Caspian Sea (2007), for the popular restatement.
In this lens, the Azerbaijani state was substantially built to manage a resource and the corridor around it, with national identity following the institutions that task required rather than leading them. Soviet planners created the Azerbaijan SSR’s heavy industrial base, workforce, and administrative apparatus primarily to extract and process Baku’s oil for the wider Soviet economy, and much of the country’s modern infrastructure, from railways to port facilities, was laid out to serve that extractive function rather than to knit together a pre-existing national community. When independence arrived in 1991, the new state inherited this resource-management apparatus more or less intact, and post-Soviet leaders, especially Heydar and Ilham Aliyev, have governed since largely as custodians and beneficiaries of that apparatus, using state oil revenue channelled through SOCAR to build political loyalty, fund the military, and finance an increasingly assertive foreign policy without needing to rely on broad-based taxation or, therefore, on the kind of public accountability taxation often forces onto a state. Nationhood, in this reading, has been cultivated on top of that resource-state structure — through education, media, and the unifying cause of Nagorno-Karabakh — but the state’s institutional bones remain those of a hydrocarbon-extraction and transit apparatus first, a nation-building project second.
Oksan Bayulgen, Foreign Investment and Political Regimes (2010).
The single process this lens identifies as most explanatory is Azerbaijan’s repeated conversion of its geography — hydrocarbon wealth plus a transit chokepoint between larger powers — into leverage disproportionate to its size. From the tsarist-era oil boom that made Baku briefly the world’s leading oil city, through Soviet-era industrialization built around the same resource, to the post-1994 opening to Western oil majors and the 2006 Baku-Tbilisi-Ceyhan pipeline that gave Azerbaijan an export route independent of both Russia and Iran, each era has seen the country’s rulers translate what sits underground, and what sits between larger neighbours, into bargaining power with those neighbours and with more distant Western and Asian markets alike. That same leverage financed the 2020 and 2023 military campaigns that reversed the 1990s territorial losses, and it now underwrites Azerbaijan’s push for transit rights, such as the proposed Zangezur corridor through southern Armenia, in the peace negotiations that have followed. Economic and geographic historians treat this as a durable pattern rather than a series of separate episodes: whatever the political system in Baku, from tsarist governorate to Soviet republic to the Aliyev presidency, has drawn its practical power from the same underlying facts of geology and location.
Oksan Bayulgen, Foreign Investment and Political Regimes (2010); Steve LeVine, The Oil and the Glory (2007), for the popular restatement.
Not a fifth lens — a note on where the four readings above genuinely disagree, and where they agree.
The sharpest genuine dispute is over origins: whether the Nagorno-Karabakh conflict was essentially inevitable — the eruption of ancient, deeply rooted Armenian-Azerbaijani rivalry once Soviet control weakened — or substantially manufactured, the delayed detonation of a boundary Bolshevik administrators drew in the 1920s for reasons that had little to do with either nation’s actual settlement or preference.
The consensus and cultural readings lean toward the first view, treating the 1988-1994 and 2020-2023 wars as a long-suppressed conflict finally surfacing; the revisionist reading leans toward the second, treating the same wars as a Soviet-drawn border finally being fought over on the ground.
A related divergence concerns the state-and-oil relationship: the economic lens treats oil revenue as the primary engine that let Azerbaijan rearm and prevail after 2020, while the revisionist lens treats Soviet-built institutions and elite networks as doing at least as much of that work, with oil money simply flowing through channels those institutions had already fixed.
What all four lenses agree on is that Azerbaijani statehood has twice been handed to its people by the collapse of a larger empire — Russian in 1918, Soviet in 1991 — rather than won through a sustained independence movement of its own, and that the country’s leadership has used the intervening periods, and the resource wealth available to it, to consolidate power at least as much as to build broad-based institutions.

As of August 2026, the conflict that defined modern Azerbaijan has moved from the battlefield to the negotiating table without fully arriving at a settled peace. Azerbaijan and Armenia initialed a peace agreement and signed a joint declaration on 8 August 2025, with United States mediation, after having announced in March 2025 that they had agreed on the text’s substance; both governments described the step as historic.
But initialing is not final signature, and final signature is not ratification: as of this writing, the treaty has not been formally signed or ratified by either country’s legislature, and analysts covering the process into 2026 describe it as a still-fragile framework rather than a concluded peace, with unresolved questions including a proposed transit corridor through southern Armenia and Armenia’s constitutional references to historic territorial claims. UCDP’s verified data record no organized-violence deaths in Azerbaijan in 2025, the first fully peaceful calendar year since the conflict began — a genuine change from three decades of intermittent war, even if the underlying dispute has not yet been formally closed.

Azerbaijan was briefly independent after the Russian Empire collapsed, then became part of the Soviet Union until 1991. During Soviet rule, Nagorno-Karabakh was placed inside Soviet Azerbaijan even though many residents were ethnic Armenians. As the USSR weakened from 1988, a separatist movement challenged Azerbaijani control. After independence, fighting escalated into a war in the early 1990s, alongside political instability and coups in the new state.
The key dispute has been between Azerbaijan and Armenia, plus the Armenia-backed self-proclaimed Republic of Artsakh. After major fighting in 2020, Azerbaijan retook the remainder of Nagorno-Karabakh in a September 2023 offensive, and Artsakh dissolved in 2024. In 2025, attention shifted to a peace process: both sides agreed on a treaty text and initialed it, but did not sign, with disagreements including Armenia’s constitution and a proposed transit route to Azerbaijan’s Nakhchivan exclave.
According to UCDP, no organized violence was recorded in Azerbaijan in 2025 for the second year in a row, but a final peace treaty with Armenia remained unsigned. The conflict’s human impact has been severe: after the 2023 offensive, almost the entire ethnic Armenian population of Nagorno-Karabakh fled. The outcome also matters internationally because Azerbaijan’s oil and natural gas reserves give it strategic influence, while relations with Russia have recently worsened.

Azerbaijan has turned natural gas exports into its most important geopolitical asset, using the Southern Gas Corridor and the Trans-Adriatic Pipeline to deepen ties with Europe while reducing reliance on any single market. In 2026, Azerbaijani gas reached 16 countries, including new deliveries to Germany and Austria, and the country remained among Europe’s important non-Russian suppliers. This gives Baku leverage in discussions with the EU, especially as Europe continues diversifying away from Russian gas. The same role also makes Azerbaijan more sensitive to European regulatory pressure and to fluctuations in regional energy demand.Sources: Reuters (16 Jan 2026), Euronews (26 Jan 2026), Carnegie Endowment (19 May 2026)
Azerbaijan has avoided openly joining the Western sanctions campaign against Russia, while keeping a careful balance between economic ties, regional security, and its partnership with Europe. At the same time, the EU has tightened sanctions enforcement against entities in Azerbaijan accused of helping Russia’s war effort, showing that Baku is exposed to scrutiny over sanctions circumvention even without being a belligerent. Azerbaijan’s gas exports to Europe have also become more valuable as Russian pipeline gas declined, which increases Azerbaijan’s importance to Europe while preserving a pragmatic working relationship with Moscow. This makes Baku a cautious swing actor rather than a frontline ally of either side.Sources: European Commission press release on EU sanctions package (20 Jul 2026), Reuters (16 Jan 2026), Carnegie Endowment (19 May 2026)
Azerbaijan’s most consequential regional rivalry is with Armenia, shaped by the conflict over Nagorno-Karabakh and the postwar security order in the South Caucasus. Baku has emerged from recent military and diplomatic successes in a stronger position than Yerevan, and its agenda now includes border delimitation, transport corridors, and the long-term consolidation of territorial gains. That rivalry directly affects Azerbaijan’s relations with Turkey, Russia, and Western states, because any peace settlement would alter regional transit and security arrangements. In practice, Azerbaijan’s foreign policy is organized around preventing a renewed Armenian challenge while maximizing its advantage in regional connectivity and trade routes.Sources: Carnegie Endowment (19 May 2026), Reuters coverage on Azerbaijan’s regional energy and diplomacy (16 Jan 2026), Euronews (26 Jan 2026)
Azerbaijan — a secular nation with a majority-Turkic and majority-Shia Muslim population — was briefly independent (from 1918 to 1920) following the collapse of the Russian Empire; it was subsequently incorporated into the Soviet Union for seven decades.
Beginning in 1988, Azerbaijan and Armenia fought over the Nagorno-Karabakh region, which was populated largely by ethnic Armenians but incorporated into Soviet Azerbaijan as an autonomous oblast in the early 1920s. In the late Soviet period, an ethnic-Armenian separatist movement sought to end Azerbaijani control over the region. Fighting over Nagorno-Karabakh escalated after Armenia and Azerbaijan gained independence from the Soviet Union in 1991. By the time a ceasefire took effect in 1994, separatists with Armenian support controlled Nagorno-Karabakh and seven surrounding Azerbaijani territories.
After decades of cease-fire violations and sporadic flare-ups, a second sustained conflict began in 2020 when Azerbaijan tried to win back the territories it had lost in the 1990s. After significant Azerbaijani gains, Armenia returned the southern part of Nagorno-Karabakh and the surrounding territories to Azerbaijan. In September 2023, Azerbaijan took military action to regain the rest of Nagorno-Karabakh; after a conflict that lasted only one day, nearly the entire ethnic Armenian population of Nagorno-Karabakh fled to Armenia.
Since gaining its independence in 1991, Azerbaijan has significantly reduced the poverty rate and has directed some revenue from its oil and gas production to develop the country’s infrastructure. However, corruption remains a burden on the economy, and Western observers and members of the country’s political opposition have accused the government of authoritarianism. The country’s leadership has remained in the ALIYEV family since Heydar ALIYEV, the most highly ranked Azerbaijani member of the Communist Party during the Soviet period, became president during the first Nagorno-Karabakh War in 1993.
As the Azerbaijan Soviet Socialist Republic, the country is tightly integrated into Soviet political, economic, and security structures. Moscow’s control suppresses open conflict over Nagorno-Karabakh, but competing Armenian and Azerbaijani claims harden, laying foundations for later armed confrontation after independence.
Political liberalization in the late Soviet period allows large demonstrations and growing violence over Nagorno-Karabakh’s status. Clashes, pogroms, and displacement radicalize both sides, turning a Soviet-era territorial dispute into an ethnic-national conflict that directly shapes Azerbaijan’s early independence years.
Azerbaijan declares independence as the USSR disintegrates, inheriting Soviet-era borders and unresolved disputes. Weak new institutions, contested leadership, and mounting war in Nagorno-Karabakh create instability, influencing later centralization of power and the prioritization of security and territorial integrity in state policy.
War breaks out between Armenian and Azerbaijani forces over Nagorno-Karabakh and surrounding districts. Azerbaijan loses territory and hundreds of thousands are displaced. The unresolved outcome leaves deep grievances and a militarized ceasefire line, driving long-term defense buildup and diplomatic efforts to reverse losses.
Former Soviet leader Heidar Aliyev takes control amid internal turmoil and battlefield setbacks. He recentralizes authority, signs a ceasefire, and pursues energy deals. His leadership style and prioritization of stability and security strongly influence the political system inherited by his successors.
A Russian-brokered ceasefire halts large-scale fighting, leaving Armenian forces in control of Nagorno-Karabakh and adjacent Azerbaijani districts. The frozen conflict framework entrenches intermittent skirmishes and negotiations, shaping Azerbaijan’s long-term strategy to rebuild forces and seek favorable conditions to change the status quo.
Azerbaijan signs a major production-sharing agreement with Western oil companies for Caspian fields. Massive energy revenues later fund military modernization and infrastructure, while pipeline diplomacy with Turkey and Europe strengthens Baku’s regional influence, affecting its leverage in the Nagorno-Karabakh dispute.
New export pipelines through Georgia and Turkey reduce dependence on Russian routes and anchor Azerbaijan in Western energy markets. Increased geopolitical weight and revenue bolster confidence in pursuing a stronger military posture, contributing to the eventual shift from frozen conflict to renewed offensives.
Ilham Aliyev becomes president after Heidar Aliyev’s illness and death, continuing a centralized, security-focused system. Under his rule, defense spending and diplomatic outreach grow, while reclaiming lost territories becomes a central national goal that frames later military and negotiation strategies.
Azerbaijan expands military cooperation with Turkey and engages with NATO’s Partnership for Peace while avoiding formal alliances that might antagonize Russia. These ties provide training and modernization support, enhancing Baku’s capabilities for later operations without committing it to binding collective defense obligations.
Development of the Southern Gas Corridor, including the TANAP and TAP pipelines, positions Azerbaijan as a key non-Russian gas supplier to Europe. Growing interdependence with EU markets reinforces Baku’s regional standing while encouraging avoidance of prolonged instability that might threaten energy exports.
A short but intense flare-up along the Nagorno-Karabakh line of contact sees Azerbaijan regain small areas of territory. The clashes reveal its improved military capabilities and readiness to use force, foreshadowing the larger offensive that will eventually alter the conflict’s territorial map.
Azerbaijan launches a major offensive, retaking significant territories around and within Nagorno-Karabakh with Turkish support and Russian mediation. A ceasefire introduces Russian peacekeepers and corridors. The outcome boosts Baku’s confidence and sets the stage for pushing to restore full control later.
A rapid Azerbaijani operation leads to the dissolution of the self-proclaimed Nagorno-Karabakh authorities and mass Armenian departure. Baku reasserts sovereignty over the region without extended fighting into 2024, helping explain the absence of recorded state-based armed conflict in current datasets.
