Azerbaijan

From the fire-altars of Caucasian Albania and the Shirvanshahs' Baku to the oil boom, the 1918 republic, Soviet rule and renewed independence.

The land between the Greater Caucasus and the Caspian Sea carries one of the deepest records of human habitation in the region — the 40,000-year-old rock art of Gobustan, the ancient kingdom of Caucasian Albania, and a Zoroastrian heritage of natural-gas fires that gave Azerbaijan its name as the "land of fire." After the Arab conquests brought Islam in the seventh century and the Seljuks made Oghuz Turkic the dominant tongue, the medieval Shirvanshahs built their walled capital at Baku around the Maiden Tower, and the Safavids of Ardabil drew the country into the Persian world. Russia annexed the eastern Caucasus khanates by the treaties of Gulistan (1813) and Turkmenchay (1828), and the late-nineteenth-century Baku oil boom made the city a world energy capital. In 1918 the short-lived Azerbaijan Democratic Republic became the first secular parliamentary republic in the Muslim world before Soviet annexation in 1920; the modern Republic of Azerbaijan restored its independence on 18 October 1991.

Restoration of state independence

18 October 1991

The modern Republic of Azerbaijan dates its political founding to 18 October 1991, when the Supreme Council adopted the Constitutional Act on the State Independence of the Republic of Azerbaijan, declaring the country the legal successor of the Azerbaijan Democratic Republic of 1918–1920 and ending more than seven decades of Soviet rule; the act was confirmed by referendum on 29 December 1991. Azerbaijan had earlier declared sovereignty in 1989 and, after the failed August 1991 coup in Moscow, adopted a declaration on restoring independence on 30 August 1991. The United States recognised Azerbaijan's independence on 25 December 1991 and established diplomatic relations on 19 February 1992. The republic inherited a land of extraordinary depth — Caucasian Albania, the Shirvanshahs' Baku, Persian khanates and a century of Russian and Soviet rule — and a brief but pioneering experiment in parliamentary democracy in 1918.

Gobustan, Caucasian Albania and the land of fire

From Palaeolithic rock carvings to an ancient Christian kingdom and a landscape of perpetual natural-gas flames.

Human use of this land reaches back to the Upper Palaeolithic. On a plateau of rocky boulders south of Baku, the Gobustan reservation preserves more than 6,000 rock engravings bearing testimony to some 40,000 years of human activity, alongside inhabited caves, settlements and burials. Inscribed by UNESCO in 2007, Gobustan's images of hunters, animals, dancers and reed boats document the lifeways of the people who occupied the semi-desert after the last Ice Age, and the continuity of human presence from prehistory into the Middle Ages.

In antiquity the region between the Greater Caucasus and the Aras River was the kingdom of Caucasian Albania, one of the three Christian states of the South Caucasus alongside Armenia and Georgia. The Albanians established a kingdom around the 1st century BCE; their king Urnayr adopted Christianity as the state religion in the 4th century CE, and the kingdom became a province under the Sasanian Persian Empire. The Greek geographer Strabo described a land of many tribes, and the country kept its own church and script until the upheavals of the Arab conquest.

The land's Zoroastrian heritage left an enduring signature. Natural gas seeping from the Abşeron Peninsula fed perpetual flames that made the area a centre of fire worship, and the name Azerbaijan is traditionally linked to fire — the "land of fire." At Surakhany near Baku a pentagonal fire-temple complex, the Ateshgah, grew up over an ancient place of worship; its altar burned with natural gas until petroleum works cut off the supply in the 1880s. The temple is on Azerbaijan's UNESCO tentative list as a monument to this fire-worshipping past.

More than 6,000 rock engravings bearing testimony to 40,000 years of rock art.

Chapter 02 · 7th century – 1500

Islam, the Seljuks and the Shirvanshahs' Baku

Arab conquest brought Islam, Turkic migration reshaped the people, and the Shirvanshahs walled their Caspian capital.

Arab armies reached the eastern Caucasus in the seventh century, beginning roughly four centuries of Arab control and introducing Islam, which gradually displaced Zoroastrianism and the Albanian church. Power devolved to local Muslim rulers, and the region became a frontier of the Islamic world. In the eleventh century the Seljuk Turks swept across the Caucasus; their invasions changed the composition of the population and established the linguistic dominance of Oghuz Turkic, the ancestor of the modern Azerbaijani language. The land thus became Turkic in speech while remaining tied to the Persian cultural sphere.

From this period the Shirvanshahs, a long-lived line of local rulers, dominated the northeastern lands around the Caspian. By the eleventh century Baku had come into their possession, and in the twelfth century they made it their capital. They fortified the old town, Icheri Sheher, behind defensive walls and raised the great cylindrical Maiden Tower (Qız Qalası), a 12th-century monument some 27 metres high standing over still older structures. Baku grew into a walled Caspian port whose layers — Zoroastrian, Sasanian, Arab, Persian and Shirvani — were later recognised by UNESCO.

Across the wider region of historic Azerbaijan, art, trade and learning flourished under a succession of Muslim dynasties, and the poet Nizami Ganjavi of Ganja became one of the greatest figures of medieval Persian literature. The Shirvanshahs continued to rebuild their seat of power, and in the fifteenth century constructed the Palace of the Shirvanshahs in the inner city — a complex of reception hall, mosque, mausoleum and bath-house that is counted among the pearls of Azerbaijani architecture.

Chapter 03 · 1500 – 1870

Persian khanates and Russian annexation

The Safavids drew the land into Shia Persia; then Russia took the khanates of the eastern Caucasus by treaty.

In 1501 Ismail I, descendant of the Sufi order founded by Sheikh Safi al-Din of Ardabil, was enthroned as shah at Tabriz with his power base in Azerbaijan, and proclaimed Twelver Shia Islam the state religion of his new Safavid empire. The dynasty drew the historic Azerbaijani lands firmly into the Persian world and helped make Shiism the dominant faith of the population — a heritage that still distinguishes Azerbaijan among Turkic-speaking nations. After Safavid power waned in the eighteenth century, the region fragmented into a patchwork of Persian-ruled khanates in Shirvan, Baku, Ganja, Karabakh, Nakhichevan and beyond.

These khanates formed the frontier where the expanding Russian Empire met Qajar Persia. Two Russo-Persian wars settled the matter. By the Treaty of Gulistan in 1813, Persia ceded to Russia a wide band of the eastern Caucasus, from Lankaran northward to Derbent, including Baku, Shirvan, Ganja and Karabakh. The Treaty of Turkmenchay in 1828 confirmed and extended Russian control, adding Nakhichevan and Yerevan. The frontier the treaties drew along the Aras River endures today, dividing the Azeri-speaking Caucasus from Iranian Azerbaijan to the south.

Russian rule reorganised the conquered khanates into provinces and bound the region to a vast empire. Incorporation brought new schools, administration and contact with European ideas, opening an outlet for educated Azerbaijanis, some of whom turned from a religious upbringing toward a more secular outlook. The seeds of a modern national and reformist consciousness were sown under the tsars — even as the population remained, in its own self-understanding, part of the larger Muslim world rather than a continuous national tradition.

The Treaties of Golestan and Turkmenchay gave the Azeri-speaking area of the Caucasus to the Russian Empire, permanently separating it from Iranian Azerbaijan.

Chapter 04 · 1870 – 1920

The Baku oil boom and the 1918 republic

Caspian oil made Baku a world energy capital — and gave birth to the Muslim world's first parliamentary republic.

Commercial exploitation of Baku's oil began in 1872, and within a generation the Abşeron fields transformed the city. By 1900 the Baku oil field was the largest in the world, drawing capital, engineers and a multi-ethnic industrial workforce, and remaining the largest field in what became the Soviet Union until the 1940s. Oil wealth built grand mansions and a turbulent labour movement; it also made Baku a strategic prize fought over in the chaos that followed the Russian Revolution of 1917.

As the Russian Empire collapsed, Azerbaijani national politics crystallised around the Musavat ("Equality") party, founded in 1911 and led by Mammad Amin Rasulzade. On 28 May 1918 the Azerbaijan Democratic Republic declared independence — the first secular, parliamentary and democratic republic in the Muslim world. Its parliament, convened in December 1918, enacted progressive measures: in July 1919 it extended the vote to all citizens aged twenty and over, making Azerbaijan one of the first countries in the Muslim East to grant women the right to vote, ahead of many Western states.

The republic's independence proved brief. Caught between Bolshevik Russia, Ottoman and British intervention, and the unresolved dispute with Armenia over Karabakh, the young state could not survive the Soviet advance. In April 1920 the Red Army marched into Baku against little resistance, and Azerbaijan was incorporated into Soviet rule. The democratic republic lasted scarcely two years, but its flag, parliament and ideals would be claimed as the foundation of the independent Azerbaijan reborn in 1991.

By the beginning of the 20th century, the Baku oil field was the largest in the world.

Chapter 05 · 1920 – 1991

The Azerbaijan SSR

Seven decades inside the Soviet Union — oil for Moscow, industrial growth, and the autonomy of Nagorno-Karabakh.

Sovietisation reshaped Azerbaijan. After a brief Transcaucasian federation, the Azerbaijan Soviet Socialist Republic was established and, from 1936, became a full union republic of the USSR. Baku's oil fuelled Soviet industrialisation and was a vital prize in the Second World War, when Nazi Germany drove toward the Caucasus seeking its fields. Soviet rule brought mass literacy, industrialisation and urban growth, alongside collectivisation, purges and the suppression of religious and national expression — and a switch of the Azerbaijani alphabet first to Latin and then to Cyrillic.

Within the republic, the mountainous region of Nagorno-Karabakh — populated by an Armenian majority — was constituted in 1923 as an autonomous oblast inside Soviet Azerbaijan. The arrangement froze a contested status quo for decades. As Moscow's grip loosened under perestroika in the late 1980s, the unresolved question erupted: in 1988 the region's Armenian majority demonstrated for transfer to Armenia, igniting intercommunal violence and a dispute that would outlast the Soviet Union itself.

The career of Heydar Aliyev spanned and outlived the Soviet system. A former KGB officer, he rose to lead the Azerbaijani Communist Party in 1969 and joined the Soviet Politburo in Moscow before his fall in the late 1980s. As the USSR disintegrated, Azerbaijan declared sovereignty in 1989 and, after the failed August 1991 coup in Moscow, moved toward full independence — closing the Soviet chapter and reopening the contest over Karabakh as an interstate war.

Chapter 06 · 1991 – present

Independence, the Aliyev era and Karabakh

A restored republic built on Caspian oil and gas, ruled by a single family — and the long, violent contest over Nagorno-Karabakh.

Azerbaijan restored its independence on 18 October 1991, declaring itself the successor of the 1918 republic; the move was confirmed by referendum that December, and the United States recognised the new state on 25 December 1991, establishing diplomatic relations in February 1992. The early years were turbulent. War with Armenia over Nagorno-Karabakh went badly for Azerbaijan, and political instability brought the fall of two presidents. In June 1993 Heydar Aliyev, the veteran Soviet-era leader, returned to power, founding a durable order; a 1994 ceasefire left Armenian forces in control of Nagorno-Karabakh and surrounding districts, with large numbers displaced on both sides.

Aliyev anchored the new state on Caspian hydrocarbons. Major contracts with international oil companies and the construction of export pipelines turned oil and gas into the backbone of the economy and the basis of state power. In 2003 the ailing Heydar Aliyev was succeeded by his son Ilham Aliyev, who has governed since, channelling oil wealth into rapid growth, a transformed Baku skyline and a much-expanded military — while drawing criticism for authoritarian rule. Azerbaijan became one of the world's most hydrocarbon-dependent economies and a significant gas supplier to Europe.

The Karabakh conflict, treated here without taking sides, was reopened by force. In a 44-day war in the autumn of 2020, Azerbaijani forces — aided by Turkish and other support — retook much of the territory, capturing the town of Shusha before a Russian-brokered ceasefire on 9 November 2020. In September 2023 a further Azerbaijani offensive brought the entire region under Baku's control; the self-declared Armenian authorities dissolved, and by international estimates more than 100,000 of roughly 120,000 ethnic Armenians fled. Casualty and displacement figures from the conflict are estimates and remain disputed.

By October more than 100,000 of about 120,000 ethnic Armenians in the region had fled.
