The South Caucasus, also known as Transcaucasia, or the Transcaucasus, is a geographical region on the border of Eastern Europe and West Asia, straddling the southern Caucasus Mountains.[1][2] The South Caucasus roughly corresponds to modern Armenia, Georgia, and Azerbaijan, which are sometimes collectively known as the Caucasian States. The total area of these countries measures about 186,100 square kilometres (71,850 square miles).[3] The South Caucasus and the North Caucasus together comprise the larger Caucasus geographical region that divides Eurasia.
Geography
[edit]The South Caucasus spans the southern portion of the Caucasus Mountains and their lowlands, straddling the border between the continents of Europe and Asia, and extending southwards from the southern part of the Main Caucasian Range of southwestern Russia to the Turkish and Armenian borders, and from the Black Sea in the west to the Caspian Sea coast of Iran in the east. The area includes the southern part of the Greater Caucasus mountain range, the entire Lesser Caucasus mountain range, the Colchis Lowlands, the Kura-Aras Lowlands, Qaradagh, the Talysh Mountains, the Lankaran Lowland, Javakheti and the eastern portion of the Armenian Highlands.
All of present-day Armenia is in the South Caucasus; the majority of present-day Georgia and Azerbaijan, including the exclave of Nakhchivan, also fall within the region.[citation needed] Parts of Iran and Turkey are also included within the region of the South Caucasus.[4][which?] Goods produced in the region include oil, manganese ore, tea, citrus fruits, and wine. It remains one of the most politically tense regions in the post-Soviet area, and contains two heavily disputed areas: Abkhazia and South Ossetia. Between 1878 and 1917, the Russian-controlled province of Kars Oblast and the county of Surmalu uezd (present-day Iğdır Province) were also incorporated into administrative regions of the South Caucasus.[citation needed]
Etymology
[edit]Nowadays, the region is referred to as the South Caucasus or Southern Caucasia (Armenian: Հարավային Կովկաս, romanized: Haravayin Kovkas; Azerbaijani: Cənubi Qafqaz; Abkhaz: Агырҭ Кавказ, romanized: Agyrt Kavkaz; Georgian: სამხრეთ კავკასია, romanized: samkhret k'avk'asia; Russian: Южный Кавказ, romanized: Yuzhnyy Kavkaz). The former name of the region, Transcaucasia, is a Latin rendering of the Russian-language word Zakavkazye (Закавказье), meaning "[the area] beyond the Caucasus".[3] This implies a Russian vantage point, and is analogous to similar terms such as Transnistria and Transleithania. Other, rarer forms of this word include Trans-Caucasus and Transcaucasus (Russian: Транскавказ, romanized: Transkavkaz).
History
[edit]Prehistory
[edit]Herodotus, a Greek historian who is known as 'the Father of History' and Strabo, a Greek geographer, philosopher, and historian, spoke about autochthonous peoples of the Caucasus in their books. In the Middle Ages, various people, including Scythians, Alani, Huns, Khazars, Arabs, Seljuq Turks, and Mongols settled in Caucasia. These invasions influenced on the culture of the peoples of the South Caucasus. In parallel Middle Eastern influence disseminated the Iranian languages and Islamic religion in Caucasus.[3]


Located on the peripheries of Iran, Russia and Turkey, the region has been an arena for political, military, religious, and cultural rivalries and expansionism for centuries. Throughout its history, the region has come under control of various empires, including the Achaemenid, Neo-Assyrian Empire,[5] Parthian, Roman, Sassanian, Byzantine, Umayyad, Abbassid, Mongol, Ottoman, successive Iranian (Safavid, Afsharid, Qajar), and Russian Empires, all of which introduced their faiths and cultures.[6] Throughout history, most of the South Caucasus was usually under the direct rule of the various in-Iran based empires and part of the Iranian world.[7] In the course of the 19th century, Qajar Iran had to irrevocably cede the region (alongside its territories in Dagestan, North Caucasus) as a result of the two Russo-Persian Wars of that century to Imperial Russia.[8]
Ancient kingdoms of the region included Colchis, Urartu, Iberia, Armenia and Albania, among others. These kingdoms were later incorporated into various Iranian empires, including the Achaemenid Empire, the Parthian Empire, and the Sassanid Empire, during which Zoroastrianism became the dominant religion in the region. However, after the rise of Christianity and conversion of Caucasian kingdoms to the new religion, Zoroastrianism lost its prevalence and only survived because of Persian power and influence still lingering in the region. Thus, the South Caucasus became the area of not only military, but also religious convergence, which often led to bitter conflicts with successive Persian empires (and later Muslim-ruled empires) on the one side and the Roman Empire (and later the Byzantine Empire and Russian Empire) on the other side.
The Iranian Parthians established and installed several eponymous branches in the South Caucasus, namely the Arsacid dynasty of Armenia, the Arsacid dynasty of Iberia, and the Arsacid dynasty of Caucasian Albania.
Middle ages and Russian rule
[edit]In the middle of the 8th century, with the capture of Derbend by the Umayyad armies during the Arab–Khazar wars, most of the South Caucasus became part of the Caliphate and Islam spread throughout[dubious – discuss] the region.[9] Later, the Orthodox Christian Kingdom of Georgia dominated most of the South Caucasus. The region was then conquered by the Seljuk, Mongol, Turkic, Safavid, Ottoman, Afsharid and Qajar dynasties.
After two wars in the first half of the 19th century, namely the Russo-Persian War (1804-1813) and the Russo-Persian War (1826-1828), the Russian Empire conquered most of the South Caucasus (and Dagestan in the North Caucasus) from the Iranian Qajar dynasty, severing historic regional ties with Iran.[7][10] By the Treaty of Gulistan that followed after the 1804-1813 war, Iran was forced to cede modern-day Dagestan, Eastern Georgia, and most of the Azerbaijan Republic to Russia. By the Treaty of Turkmenchay that followed after the 1826-1828 war, Iran lost all of what is modern-day Armenia and the remainder of the contemporary Azerbaijani Republic that remained in Iranian hands. After the 1828-1829 war, the Ottomans ceded Western Georgia (except Adjaria, which was known as Sanjak of Batum), to the Russians, who populated this new southern boundary mostly with undesirable citizens and tolerated heretics (sektanty).[11]
In 1844, what comprises present-day Georgia, Armenia, and Azerbaijan were combined into a single czarist government-general, which was termed a vice-royalty in 1844-1881 and 1905–1917. Following the 1877-78 Russo-Turkish War, Russia annexed Kars, Ardahan, Agri and Batumi from the Ottomans, joined to this unit, and established the province of Kars Oblast as its most south-westerly territory in the South Caucasus.
Modern era
[edit]
After the fall of the Russian Empire in 1918, the South Caucasus region was unified into a single political entity twice, as the Transcaucasian Democratic Federative Republic from 9 April 1918 to 26 May 1918,[12] and as the Transcaucasian Socialist Federative Soviet Republic from 12 March 1922 to 5 December 1936.
Both times these Transcaucasian entities dissolved, although the region would remain politically bound together in the Soviet Union in the form of the three separate Soviet Socialist Republics of Armenia, Azerbaijan and Georgia.[13] When the Soviet Union dissolved in 1991, all three emerged as internationally recognized sovereign states. Transit through the South Caucasus has been hampered since 1989 due to the ongoing Turkish–Azeri blockade of Armenia.
The Russo-Georgian War took place in 2008 across the South Caucasus, contributing to further instability in the region, which is as intricate as the Middle East, due to the complex mix of religions (mainly Muslim and Orthodox Christian) and ethno-linguistic groups.
Since their independence, the three countries have had varying degrees of success in their relations with Russia and other countries. In Georgia, after the Rose Revolution in 2004, the country, like the Baltic states, began integrating into wider European society by opening up relations with NATO and the European Union. Armenia continues to foster relations with Russia, while also developing ties with the EU. Azerbaijan relies less on Russia, strategically partnering with Turkey. All three South Caucasus countries are members of the Council of Europe, the Organization for Security and Co-operation in Europe, the European Political Community, and participate in the EU's Eastern Partnership and Euronest Parliamentary Assembly. All three South Caucasus countries are also members of NATO's Euro-Atlantic Partnership Council and Partnership for Peace.
On 8 November 2023, the European Commission issued an official recommendation to grant EU candidate status to Georgia, which was confirmed on 14 December 2023. Georgia, thus becoming, the first country in the South Caucasus to receive EU candidate status.[14] On 12 March 2024, the European Parliament passed a resolution confirming Armenia meets Maastricht Treaty Article 49 requirements and that the country may apply for EU membership.[15] On 12 February 2025, Armenia's parliament approved a bill officially endorsing Armenia's EU accession.[16]

Wine
[edit]The South Caucasus, in particular where modern-day Turkey, Georgia, Armenia and Iran are located, is one of the native areas of the wine-producing vine Vitis vinifera.[32] Some experts speculate that the South Caucasus may be the birthplace of wine production.[33] Archaeological excavations and carbon dating of grape seeds from the area have dated back to 8000–5000 BC.[34] Wine found in Iran has been dated to c. 7400 BC[32] and c. 5000 BC,[35] while wine found in Georgia has been dated to c. 8000 BC.[36][37][38] The earliest winery, dated to c. 4000 BC, was found in Armenia.[32]

South Caucasus
View on GrokipediaGeography
Physical Features and Borders
The South Caucasus occupies the area south of the Greater Caucasus mountain range, positioned between the Black Sea to the west and the Caspian Sea to the east, primarily comprising the states of Georgia, Armenia, and Azerbaijan. This region features predominantly mountainous terrain shaped by the Lesser Caucasus range, which extends across southern Georgia, Armenia, and Azerbaijan, creating deep valleys, high plateaus, and limited lowland areas. Elevations in the Lesser Caucasus typically range below 3,000 meters, with the highest peak, Mount Aragats in Armenia, reaching 4,090 meters.[10][11] Major rivers define hydrological features, including the Kura River, which originates in the mountains of Georgia, flows 1,515 kilometers through Azerbaijan, and discharges into the Caspian Sea, draining a basin of 188,000 square kilometers. The Aras River, approximately 1,070 kilometers long, originates in eastern Turkey, forms sections of the Armenia-Azerbaijan and Azerbaijan-Iran borders, and joins the Kura near its mouth. These waterways, fed by snowmelt and precipitation from surrounding highlands, support agriculture in valleys but are prone to seasonal flooding and erosion in the rugged landscape.[12][13] The borders of South Caucasus states reflect their enclosed geography, with no direct access to open oceans—Armenia is fully landlocked, while Georgia and Azerbaijan touch inland seas. Georgia's northern boundary follows the Greater Caucasus with Russia, spanning about 894 kilometers; its southwestern frontier abuts Turkey (273 km), southern with Armenia (219 km), and southeastern with Azerbaijan (480 km). Armenia borders Georgia (221 km) to the north, Azerbaijan (1,011 km, including disputed segments) to the east, Iran (44 km) to the south, and Turkey (277 km) to the west. Azerbaijan shares frontiers with Georgia (605 km) and Russia (390 km, including the Nakhchivan exclave) to the northwest, Armenia to the west, and Iran (765 km) to the south, enclosing the Caspian Sea coast.[14][1] Disputed territories alter de facto control: Abkhazia and South Ossetia, recognized internationally as Georgian but administered separately with Russian military presence since 2008, occupy northwestern Georgia along the Black Sea and central highlands. The Nagorno-Karabakh enclave, historically contested between Armenia and Azerbaijan, came under full Azerbaijani control after offensives in 2020 and September 2023, prompting ethnic Armenian exodus; subsequent delimitation in May 2024 saw Armenia cede four border villages totaling 12.7 kilometers to align with Soviet-era lines. These areas, amid ongoing peace talks, highlight persistent tensions over physical boundaries drawn largely from 1920s Soviet delineations.[1][15][16]Climate and Natural Resources
The South Caucasus features diverse climates shaped by its topography, including the Greater and Lesser Caucasus Mountains, which create barriers to moisture and temperature moderation. Armenia predominantly experiences a highland continental climate, characterized by hot summers with mean temperatures around 25°C and cold winters averaging -5°C, transitioning to more arid conditions in lower elevations and alpine influences in higher mountains.[17][18] Georgia's climate varies from Mediterranean-like warmth along the Black Sea coast, with mild winters and annual precipitation exceeding 1,000 mm, to continental conditions in the east, where summers are warmer and drier.[19] Azerbaijan's climate is largely dry and semiarid steppe in the central lowlands, with hot summers up to 30°C and mild winters, while the southeastern Talish Mountains receive humid subtropical conditions with up to 1,725 mm of annual rainfall.[20][21] Recent data indicate warming trends across the region, with Armenia recording an average temperature rise of 1.23°C from 1929 to 2016, and similar increases in Azerbaijan and Georgia exacerbating water scarcity and agricultural variability.[22] Precipitation is uneven, concentrated in western Georgia due to Black Sea influences, while eastern areas and Armenian highlands are prone to droughts, influencing agriculture and hydropower reliability. Natural resources in the South Caucasus include hydrocarbons concentrated in Azerbaijan, which holds proven petroleum reserves and major natural gas fields on the Apsheron Peninsula and Caspian shelf, underpinning its economy with exports exceeding 1 million barrels of oil per day as of recent production figures.[20][23] Armenia features small deposits of gold, copper, molybdenum, zinc, and bauxite, with mining contributing modestly to GDP through operations like the Zangezur Copper-Molybdenum Combine.[17] Georgia relies on timber, hydropower from rivers like the Kura, and mineral deposits including manganese (world's fifth-largest reserves at Chiatura), iron ore, and copper, though exploitation is limited by infrastructure.[19] Forests cover about 10-12% of land in Armenia and Georgia, serving as key resources for wood products and biodiversity, while all three countries harness hydropower potential from mountainous terrain, generating over 80% of electricity in Georgia and Armenia.[24] Arable land supports agriculture, with irrigation drawing from shared rivers like the Aras, but resource extraction has raised environmental concerns, including pollution from Azerbaijan's oil fields and deforestation pressures in Georgia.[19]Definition and Scope
Constituent Territories
The South Caucasus consists of the territories of three sovereign states: Armenia, Azerbaijan, and Georgia, which emerged as independent nations following the dissolution of the Soviet Union in 1991. These states collectively cover approximately 186,000 square kilometers and are home to over 17 million people as of 2025. The region's boundaries are shaped by the Greater Caucasus mountains to the north, the Lesser Caucasus to the south, and the Black Sea to the west, with Azerbaijan extending eastward to the Caspian Sea. Disputed enclaves, including Abkhazia and South Ossetia within Georgia and the Nagorno-Karabakh region within Azerbaijan, complicate territorial claims, though they are internationally recognized as integral to the respective sovereign states. Armenia occupies 29,743 square kilometers of mountainous terrain, rendering it landlocked and reliant on neighbors for trade access. Its population stands at 2,945,438 as of October 2025, with the vast majority ethnic Armenians. The capital, Yerevan, serves as the political, economic, and cultural hub, housing over one million residents. Armenia's territory has remained stable since independence, though border demarcations with Azerbaijan remain contentious following the 2020 and 2023 conflicts over Nagorno-Karabakh.[25][26][27] Azerbaijan spans 86,600 square kilometers, including the Azerbaijani exclave of Nakhchivan separated by Armenia, and possesses substantial [Caspian Sea](/page/Caspian Sea) coastline. The population is estimated at 10,397,713 in mid-2025, predominantly ethnic Azerbaijanis, with Baku as the capital and largest city, boasting over 2.4 million inhabitants. Azerbaijan's territory expanded de facto after regaining control of Nagorno-Karabakh in 2023, where approximately 30,000 to 40,000 Azerbaijanis had returned by late 2025 amid ongoing reconstruction, following the exodus of over 100,000 ethnic Armenians. The region, internationally affirmed as Azerbaijani sovereign territory, was administered separately by ethnic Armenian authorities until its dissolution in September 2023.[28][21][29][30] Georgia encompasses 69,700 square kilometers, featuring diverse landscapes from Black Sea coastlines to highland plateaus. Its population is 3,704,500 as of January 2025, excluding de facto independent regions, with Tbilisi as the capital hosting about 1.1 million people. Internationally, Georgia's territory includes Abkhazia (8,665 square kilometers, population around 244,000) and South Ossetia (3,900 square kilometers, population 56,520), both of which declared independence in the early 1990s and gained de facto control after the 2008 Russo-Georgian War, with recognition limited to Russia and four other states. These entities maintain separate administrations, currencies tied to the Russian ruble, and military presence dominated by Russian forces, despite Georgia's constitutional claims and UN resolutions affirming their integral status.[31][32][33][34][35]Etymology and Alternative Names
The name "Caucasus" originates from the Ancient Greek Kaúkasos (Καύκασος), adopted into Latin as Caucasus, with its ultimate roots possibly tracing to the Hittite term Kaz-kaz, referring to a people on the southern shore of the Black Sea, or to Scythian words evoking "white" or "shining" in reference to the snow-capped peaks.[36] [37] The specifier "South" denotes the portion of this mountain system and adjacent lowlands lying south of the main Greater Caucasus range, encompassing the modern states of Armenia, Azerbaijan, and Georgia, as distinct from the North Caucasus within Russia.[36] Historically, the region has been termed Transcaucasia (or Transcaucasus), a Latinized form of the Russian Zakavkaz'ye (Закавказье), meaning "the land beyond the Caucasus" from a northern, Russian imperial vantage point, a nomenclature prominent during the 19th and 20th centuries under Tsarist and Soviet rule.[38] [39] This exonym implies a peripheral status relative to Russia and has been critiqued for its Eurocentric bias, prompting post-Soviet adoption of the neutral geographic descriptor "South Caucasus" in international discourse since the 1990s.[40] Less commonly, variants like "Southern Caucasia" or, among some Azerbaijani perspectives, "Central Caucasus" appear, though the latter reframes Iranian territories as southern extensions.[38]Historical Overview
Prehistory and Ancient Civilizations
The earliest evidence of hominin presence in the South Caucasus dates to the Lower Paleolithic period, with fossils from the Dmanisi site in southern Georgia representing some of the oldest well-dated remains outside Africa, aged approximately 1.85 to 1.77 million years. These include skulls and tools attributed to early Homo erectus or related forms, indicating a population with small brain sizes and a mix of primitive and derived traits adapted to diverse environments.[41][42] Additional Paleolithic sites, such as Azykh Cave in Azerbaijan, yield stone tools like choppers from comparable early periods, suggesting widespread hunter-gatherer occupations across the region.[43] Neolithic developments emerged around 6000 BCE with the Shulaveri-Shomu culture in the Kura River basin spanning modern Georgia and Azerbaijan, featuring early pottery, mud-brick architecture, and proto-agricultural practices including animal domestication.[44] By the Early Bronze Age, the Kura-Araxes culture (ca. 4000–2000 BCE) dominated the South Caucasus, characterized by black-burnished pottery, fortified hilltop settlements, and metallurgical advancements in copper and arsenic alloys, with expansions into eastern Anatolia and northern Mesopotamia reflecting mobile pastoralist economies.[45] Sites like those in the Aras Valley show continuity in burial practices and obsidian trade networks.[46] In the Iron Age, distinct polities arose amid influences from neighboring empires. The Kingdom of Urartu, centered around Lake Van in the Armenian Highlands from the 9th to 6th centuries BCE, developed hydraulic engineering, massive fortresses, and cuneiform inscriptions detailing military campaigns against Assyria, with its core territory encompassing parts of modern Armenia, eastern Turkey, and northwestern Iran.[47] To the west, Colchis in the eastern Black Sea region of Georgia, emerging by the late 2nd millennium BCE, was known for gold mining, advanced bronze work, and interactions with Greek colonists from the 8th century BCE onward, supplying resources like hides and linen.[48] Eastern Georgia hosted the Kingdom of Iberia (Kartli), with roots in Bronze Age settlements and consolidation by the 6th century BCE, featuring Zoroastrian influences and alliances against Persian expansion.[48] In the southeast, Caucasian Albania, occupying territories in modern Azerbaijan from the 4th century BCE, maintained a Caucasian language and early Christian temples by the 5th century CE, distinct from Indo-European neighbors.[49] These entities shared metallurgical traditions but diverged in linguistics and governance, setting patterns for later regional dynamics.Medieval Kingdoms and Invasions
Following the Arab conquests of the 7th century, which incorporated much of the South Caucasus into the Umayyad and later Abbasid caliphates, local principalities began asserting autonomy by the 9th century through tribute arrangements and revolts against caliphal authority.[50] In Armenia, the Bagratuni dynasty, tracing origins to the 4th century but rising prominently after Arab domination, secured recognition from the Abbasid caliph in 884 when Ashot I Bagratuni was crowned king, establishing the Bagratid Kingdom of Armenia (885–1045) centered in Ani, which flourished as a trade and cultural hub with Byzantine and Islamic influences.[51] This kingdom reached its zenith under kings like Gagik I (990–1020), who expanded territories westward toward the Black Sea, though internal divisions and external pressures fragmented it by the mid-11th century.[50] In Georgia, the Bagrationi dynasty, a branch of the same Bagratuni line, unified eastern and western principalities—the Kingdom of Iberia (Kartli) and the Kingdom of Abkhazia—under Bagrat III around 1008, forming the Kingdom of Georgia that extended influence over parts of Armenia and Azerbaijan.[52] The kingdom's Golden Age commenced under David IV (r. 1089–1125), who reformed the military, resettled populations from the Cumans to bolster defenses, and decisively defeated a larger Seljuk Turkish force at the Battle of Didgori on August 12, 1121, reclaiming Tbilisi and much of southern Georgia from Turkic incursions that had intensified since the 1040s under leaders like Alp Arslan.[52] David's successor, Tamar (r. 1184–1213), oversaw territorial expansion to the Black Sea and Caspian, fostering a cultural renaissance with patronage of Georgian Orthodox monasteries and literature, though her reign marked the empire's peak before Mongol arrivals.[52] In the Azerbaijan region, the Shirvanshahs emerged as an independent Muslim dynasty around 861 under the Rawadid (Mazyadid) family, ruling from Shamakhi and later Baku as semi-autonomous vassals of caliphs, Seljuks, and Mongols, maintaining Persianate administration and Zoroastrian-influenced architecture amid Turkic migrations.[53] Their longevity—spanning nearly a millennium until 1538—stemmed from strategic alliances and fortifications, with peaks under figures like Manuchahr II (r. 1027–1054), who navigated Seljuk pressures by intermarrying with incoming Turkic elites.[54] Turkic invasions, particularly by the Seljuks from the 11th century, disrupted these kingdoms through raids and conquests, with Alp Arslan's forces capturing Ani in 1064 and imposing tribute on Georgia until David IV's victories shifted momentum.[55] The Mongol invasions of the 13th century proved more devastating: initial raids under Jebe and Subutai in 1220–1221 devastated Georgia and Armenia, followed by Batu Khan's campaigns in 1236–1240 that subjugated the region, forcing King David Ulu (r. 1247–1270) to submit as a vassal, extracting heavy tribute and depopulating areas through massacres and enslavement estimated in the tens of thousands.[56] Subsequent Ilkhanid rule integrated the South Caucasus into the Mongol-Persian sphere, eroding local sovereignty until Timurid disruptions in the late 14th century further fragmented remnants of these medieval polities.[57]Russian Empire and Soviet Integration
The Russian Empire's expansion into the South Caucasus began with the annexation of the Kingdom of Kartli-Kakheti (eastern Georgia) on January 18 (30), 1801, via a manifesto issued by Tsar Paul I, which abolished the Georgian monarchy and incorporated the territory directly into the empire, overriding prior protective arrangements like the 1783 Treaty of Georgievsk.[58] [59] This move followed Georgian appeals for Russian protection against Persian and Ottoman incursions but resulted in full subjugation, with subsequent annexations of western Georgian principalities, such as Imereti in 1810.[60] Further conquests targeted territories held by Persia, culminating in the Russo-Persian War of 1804–1813, ended by the Treaty of Gulistan on October 24, 1813, which ceded to Russia the khanates of northern Azerbaijan (including Baku, Ganja, Shirvan, Karabakh, and Sheki) along with Derbent and the Baku region.[61] [62] The subsequent Russo-Persian War of 1826–1828 concluded with the Treaty of Turkmenchay on February 22, 1828, transferring eastern Armenia (Erivan Khanate), Nakhchivan, and Talysh to Russian control, completing the empire's hold over the South Caucasus core while sparking local resistance integrated into the broader Caucasian War (1817–1864).[63] [64] Following the 1917 Bolshevik Revolution and the empire's collapse, the South Caucasus briefly achieved independence as the Democratic Republic of Georgia (May 1918), Democratic Republic of Azerbaijan (May 1918), and First Republic of Armenia (May 1918), amid the Russian Civil War and regional chaos.[65] The Red Army's invasions swiftly reversed this: Azerbaijan fell on April 27, 1920, after Bolshevik forces seized Baku; Armenia on November 29, 1920, via the 11th Red Army; and Georgia in February 1921, with the invasion commencing February 11–16, leading to the overthrow of the Menshevik government by March 18.[65] These military actions, justified by Lenin as aiding proletarian uprisings but executed through direct force, established Soviet socialist republics in each territory.[65] In March 1922, the three republics federated into the Transcaucasian Soviet Federative Socialist Republic (TSFSR), formalized as a constituent of the USSR upon its creation, with Tiflis (Tbilisi) as capital; this structure centralized control under Moscow while nominally preserving ethnic units.[65] [66] The TSFSR dissolved on December 5, 1936, under the Stalin Constitution, elevating Armenia, Azerbaijan, and Georgia to full union republics directly subordinate to the USSR, a shift attributed to administrative streamlining and intensified centralization.[67] Soviet integration emphasized economic exploitation—Azerbaijan's oil fields supplied over 70% of Soviet production by the 1940s—alongside policies like korenizatsiya (indigenization), which promoted local languages and cadres until the late 1930s, followed by Russification, forced collectivization causing famines (e.g., 1932–1933 affecting Georgia), and deliberate border delineations fostering inter-ethnic dependencies, such as assigning Armenian-majority Nagorno-Karabakh to Azerbaijan in 1923 to ensure loyalty to Moscow.[60] [68] These measures suppressed nationalism but sowed seeds for post-Soviet conflicts by prioritizing imperial control over ethnic self-determination.[69]Post-Independence Era and Conflicts
Following the dissolution of the Soviet Union in December 1991, the republics of Armenia, Azerbaijan, and Georgia emerged as independent states in the South Caucasus, inheriting ethnic and territorial disputes from the Soviet era.[70] These new governments faced immediate challenges from separatist movements and interstate conflicts, exacerbated by weak institutions, economic collapse, and external interventions, particularly from Russia, which sought to maintain influence through support for breakaway regions.[71] Independence initially brought optimism for self-determination but quickly devolved into violence, displacing hundreds of thousands and hindering regional integration.[72] The Nagorno-Karabakh conflict dominated the post-independence period, pitting Armenia against Azerbaijan over the ethnic Armenian-majority enclave of Nagorno-Karabakh, which had been administratively part of Soviet Azerbaijan despite its demographic composition. Tensions erupted into the First Nagorno-Karabakh War from 1988 to May 1994, culminating in an Armenian-backed offensive that secured control of Nagorno-Karabakh and seven adjacent districts, at a cost of roughly 30,000 lives and over 1 million refugees and internally displaced persons, primarily Azerbaijanis expelled from the seized territories.[72] A ceasefire brokered by Russia in 1994 froze the lines but left underlying grievances unresolved, with sporadic clashes, including the 2016 Four-Day War that killed hundreds on both sides.[72] The conflict's roots lay in Soviet nationalities policy, which drew borders to foster interdependence and suppress irredentism, but post-1991 power vacuums allowed ethnic mobilization to prevail over legal claims to territorial integrity.[71] Escalation resumed with Azerbaijan's military modernization, funded by oil revenues, leading to the Second Nagorno-Karabakh War from September 27 to November 10, 2020. Azerbaijani forces recaptured most occupied territories and parts of Nagorno-Karabakh proper, inflicting heavy losses on Armenian forces and resulting in around 6,000 Azerbaijani and over 4,000 Armenian military deaths, alongside civilian casualties.[73] A Russia-mediated ceasefire deployed 1,960 Russian peacekeepers to monitor the Lachin corridor and remaining Armenian-held areas, but violations persisted, including Azerbaijan's blockade of the corridor from December 2022.[73] In September 2023, Azerbaijan launched a rapid offensive, prompting the dissolution of the self-proclaimed Nagorno-Karabakh Republic and the exodus of nearly 100,000 ethnic Armenians to Armenia, effectively ending Armenian control after three decades.[16] This outcome underscored Azerbaijan's superior military capabilities and the erosion of Russian leverage, as peacekeepers withdrew amid Armenia's pivot toward Western partnerships.[74] In Georgia, separatist conflicts in Abkhazia and South Ossetia similarly undermined sovereignty post-1991. The 1992-1993 Abkhazian War saw Abkhaz forces, backed by Russian irregulars and Cossacks, expel Georgian troops and civilians, resulting in 8,000-10,000 deaths and the flight of over 200,000 Georgians, establishing de facto independence under Russian protection.[75] South Ossetia experienced parallel fighting in 1991-1992, displacing thousands and solidifying a ceasefire monitored by Russian-led forces.[75] These "frozen conflicts" served Russian strategic interests by keeping Georgia unstable and dependent, culminating in the August 2008 Russo-Georgian War, triggered by Georgia's attempt to reassert control over South Ossetia. Russian forces swiftly overran Georgian positions, occupied buffer zones, and recognized Abkhazia and South Ossetia's independence, with Georgia suffering around 400 military deaths and significant territorial losses.[75] The war highlighted Russia's use of ethnic kin as pretexts for intervention, entrenching military bases in the separatist entities and blocking Georgia's NATO aspirations.[73] By 2025, the South Caucasus saw tentative shifts toward stabilization, driven by Azerbaijan's battlefield successes and Armenia's reevaluation of Russian alliances amid the Ukraine war's distractions. Border delimitation talks advanced, with agreements on partial troop withdrawals and transport links, though full peace remained elusive due to disputes over enclaves and constitutional references to Nagorno-Karabakh in Armenia.[76] Georgia pursued EU integration, ratified in 2024 despite domestic protests, while maintaining fragile truces in its occupied regions, where Russian influence persisted through economic ties and troop presence.[73] External actors like Turkey bolstered Azerbaijan, while the EU and U.S. offered mediation incentives, potentially reshaping the region from confrontation to connectivity, contingent on resolving irredentist claims through pragmatic compromises rather than maximalist demands.[74]Political Structures
Sovereign States
The South Caucasus is composed of three internationally recognized sovereign states: Armenia, Azerbaijan, and Georgia. These nations declared independence from the Soviet Union between April and September 1991, amid its dissolution, and were admitted to the United Nations in 1992 as full members.[77][78][79] Each maintains diplomatic relations with the majority of UN member states, though territorial disputes—such as those involving Nagorno-Karabakh, Abkhazia, and South Ossetia—have strained interstate ties and prompted divergent foreign policy orientations, with Georgia aligning toward European integration, Azerbaijan leveraging energy exports for influence, and Armenia navigating post-Soviet alliances. A U.S.-brokered peace agreement between Armenia and Azerbaijan on August 8, 2025, marked progress toward normalization, including border delimitation and economic cooperation frameworks.[5] Armenia, with a 2025 estimated population of 2,952,365, operates as a unitary parliamentary republic.[25] Its capital is Yerevan, and legislative power resides in the 105-member unicameral National Assembly, elected for five-year terms via proportional representation.[80] The prime minister holds executive authority, while the president serves a largely ceremonial role following constitutional reforms in 2015 and 2018 that shifted from a semi-presidential system. Armenia's sovereignty has been tested by the 2020–2023 Nagorno-Karabakh war, culminating in Azerbaijan's military restoration of control over the region in September 2023, after which Armenia ceased support for the breakaway entity in 2024.[81] Azerbaijan, estimated at 10,397,713 people in 2025, functions as a unitary presidential republic with a population concentrated around its capital, Baku.[28] The president, directly elected for seven-year terms, wields extensive executive powers, including command of the armed forces and foreign policy direction, under a constitution adopted in 1995.[82] Independence was proclaimed on August 30, 1991, restoring the short-lived Azerbaijan Democratic Republic of 1918–1920. Azerbaijan's hydrocarbon resources have bolstered its regional leverage, particularly post-2023 when it reintegrated Nagorno-Karabakh, prompting refugee returns and infrastructure reconstruction by 2025.[83] Georgia, with a 2025 population of approximately 3,704,500, is a parliamentary republic centered in Tbilisi.[84] It declared independence on April 9, 1991, following a March referendum, and transitioned to its current system via 2017–2018 constitutional amendments that curtailed presidential powers in favor of a prime minister-led government and unicameral parliament elected every four years.[85] Georgia pursues Euro-Atlantic integration, having signed an EU Association Agreement in 2014 and receiving candidate status in 2023, despite Russian occupation of Abkhazia and South Ossetia since the 2008 war, which controls about 20% of its territory.[86]Disputed and Separatist Regions
The primary disputed and separatist regions in the South Caucasus are Abkhazia and South Ossetia, which broke away from Georgia amid ethnic conflicts in the early 1990s, and the former Nagorno-Karabakh enclave within Azerbaijan, which maintained de facto Armenian control until 2023. These territories emerged from the Soviet Union's collapse, fueled by ethnic tensions and irredentist claims, leading to wars and frozen conflicts that drew Russian intervention. Internationally, Abkhazia and South Ossetia are recognized as independent only by Russia and a handful of allies like Venezuela, Nicaragua, and Nauru, while the vast majority of states, including the United Nations members, view them as integral to Georgia.[35][87] Nagorno-Karabakh, historically an Azerbaijani oblast with an ethnic Armenian majority under Soviet administrative policy, never achieved formal recognition as the self-proclaimed Republic of Artsakh and was reintegrated into Azerbaijan following military operations in 2020 and 2023.[72][88] Abkhazia, located along Georgia's Black Sea coast, covers approximately 8,660 square kilometers and declared independence in 1992 after clashes with Georgian forces displaced tens of thousands, culminating in a 1992-1993 war that killed around 8,000 people and ethnically cleansed much of the Georgian population from the region. A 1994 ceasefire brokered by Russia established a neutral peacekeeping force, but tensions escalated in the 2008 Russo-Georgian War, after which Russia recognized Abkhazia's independence and stationed thousands of troops there, effectively controlling key decisions and infrastructure. As of 2025, Russian entities dominate Abkhazia's economy through tax exemptions on investments and military basing rights, while local governance exhibits limited autonomy amid growing anti-Russian sentiment and a "partly free" status due to restricted civil liberties.[89][90][91] South Ossetia, a landlocked enclave of about 3,900 square kilometers in Georgia's north, similarly sought separation in 1991-1992, sparking a war that resulted in Georgian withdrawal and de facto independence under Russian-backed forces, with an estimated 1,000 deaths and significant population displacements. Russian recognition followed the 2008 war, where Moscow's intervention routed Georgian troops, leading to the deployment of over 5,000 Russian border guards along the administrative boundary line, which remains disputed and militarized. In 2025, South Ossetia maintains de facto sovereignty but relies heavily on Russian subsidies covering up to 90% of its budget, with limited border reopenings to Georgia signaling minor de-escalation efforts amid predictions of potential reintegration by 2030 from Georgian officials.[35][92][93] Nagorno-Karabakh, an 4,400-square-kilometer mountainous area in Azerbaijan, was controlled by ethnic Armenian forces from 1994 until Azerbaijan's recapture of surrounding territories in the 2020 Second Karabakh War, which killed over 6,000 and shifted the military balance decisively toward Baku. A September 2023 Azerbaijani offensive, described by its government as an "anti-terror operation" to dismantle remaining separatist structures, prompted the dissolution of the Artsakh Republic on January 1, 2024, and the exodus of nearly all 100,000 ethnic Armenians, averting prolonged insurgency but raising humanitarian concerns over displacement. Peace talks between Armenia and Azerbaijan advanced in 2024-2025, including Armenia's cession of four border villages, though border demarcations and refugee returns remain unresolved, with Azerbaijan asserting full sovereignty over the region.[88][94][72][95]Ethnic Conflicts and Controversies
Nagorno-Karabakh Conflict
The Nagorno-Karabakh conflict arose from ethnic tensions between Armenians and Azerbaijanis in the Nagorno-Karabakh region, legally part of Azerbaijan since the Soviet era but predominantly inhabited by ethnic Armenians. In 1921-1923, Soviet authorities established the Nagorno-Karabakh Autonomous Oblast (NKAO) within the Azerbaijan Soviet Socialist Republic (SSR), despite Armenians constituting 89% of the population in 1926 and maintaining a majority through the Soviet period, declining to about 77% by 1989 due to policies favoring Azeri settlement.[96] Armenians historically sought unification with Armenia, citing cultural and demographic ties, while Azerbaijan asserted sovereignty based on administrative borders drawn by Soviet decree, which international law later upheld post-independence.[97] Tensions escalated in February 1988 when the NKAO regional soviet petitioned to transfer the oblast to the Armenian SSR, sparking pogroms against Armenians in Azerbaijani cities like Sumgait and Baku, displacing thousands and killing hundreds.[98] This ignited the First Nagorno-Karabakh War (1988-1994), involving Armenian forces from Nagorno-Karabakh and Armenia against Azerbaijan, resulting in approximately 30,000 deaths, including civilians, and the displacement of around 800,000 Azerbaijanis from the region and adjacent areas.[72] By May 1994, Armenian forces controlled not only the NKAO but also seven surrounding Azerbaijani districts, comprising about 20% of Azerbaijan's territory, in what Azerbaijan and most international observers classified as an occupation violating sovereignty and the 1975 Helsinki Final Act.[97] A ceasefire was signed on May 12, 1994, but without a comprehensive peace treaty, leaving the conflict frozen.[72] The OSCE Minsk Group, co-chaired by the United States, Russia, and France, was established in 1992 to mediate a settlement based on principles including territorial integrity, non-use of force, and equal rights for peoples, but talks stalled over core issues like the status of Nagorno-Karabakh and the sequence of troop withdrawals versus self-determination referenda.[99] Periodic clashes persisted, including the 2016 Four-Day War from April 2-5, which killed dozens and tested defenses but ended in a shaky truce.[100] Azerbaijan invested heavily in military modernization, including Turkish-supplied drones and artillery, reversing the prior asymmetry where Armenian forces held defensive advantages in mountainous terrain.[101] The Second Nagorno-Karabakh War erupted on September 27, 2020, lasting 44 days until a Russia-brokered ceasefire on November 9, 2020, which mandated Armenian withdrawal from occupied districts, Azerbaijan's retention of gains, and deployment of 1,960 Russian peacekeepers to secure the Lachin corridor linking Armenia to Nagorno-Karabakh.[72] Azerbaijan recaptured all seven surrounding districts and about one-third of Nagorno-Karabakh proper, including the strategically vital city of Shusha (Shushi), using precision strikes from Bayraktar TB2 drones and loitering munitions that neutralized Armenian armor and air defenses, causing an estimated 3,000-4,000 military deaths on both sides.[72][101] The outcome restored Azerbaijani control over most pre-1988 borders, diminishing the viability of an independent Armenian enclave, though Russian peacekeepers' mandate faced challenges from subsequent incidents.[88] Azerbaijan intensified pressure in 2022-2023 via a blockade of the Lachin corridor starting December 12, 2022, halting supplies and prompting humanitarian concerns, though Azerbaijan framed it as countering illicit arms smuggling.[72] On September 19, 2023, Azerbaijan launched a rapid offensive, overwhelming remaining Armenian defenses in hours and prompting the surrender of the self-declared Republic of Artsakh; official reports cited 192 Armenian military deaths and 200 total casualties, including civilians.[102] Approximately 100,000 ethnic Armenians—over 99% of the remaining population—fled to Armenia within days, citing fears of persecution despite Azerbaijani offers of citizenship and rights under its constitution; Azerbaijan rejected ethnic cleansing claims, attributing the exodus to panic incited by separatist leaders and unresolved distrust from mutual atrocities in the 1990s.[72][72] The Republic of Artsakh dissolved on January 1, 2024, ending its unrecognized existence, while Azerbaijan began reintegrating the territory as its East Zangezur province, with ongoing bilateral peace talks between Armenia and Azerbaijan addressing border delimitation and transport links.[72] The OSCE Minsk Group was formally dissolved on September 1, 2025, by mutual agreement, reflecting the conflict's resolution through Azerbaijani military success rather than negotiated compromise.[103]Abkhazia and South Ossetia Disputes
The disputes over Abkhazia and South Ossetia stem from separatist movements in these autonomous regions of Soviet-era Georgia, which intensified following Georgia's declaration of independence from the Soviet Union on April 9, 1991.[104] Abkhazia, located along the Black Sea coast, and South Ossetia, in the central Caucasus mountains, had been granted autonomous status within the Georgian Soviet Socialist Republic, fostering distinct ethnic identities among Abkhazians and Ossetians, who share linguistic and cultural ties with populations in Russia.[104] Tensions escalated as Georgia moved to centralize control, prompting referendums and declarations of independence by the regions: South Ossetia on December 21, 1991, and Abkhazia maintaining de facto separation after initial autonomy demands.[105] The First South Ossetia War (January 1991–June 1992) involved clashes between Georgian forces and Ossetian militias, resulting in approximately 1,000 deaths and the displacement of around 100,000 people, primarily ethnic Georgians.[104] A ceasefire was brokered in Sochi on June 24, 1992, establishing a Joint Control Commission and peacekeeping forces comprising Georgian, Ossetian, and Russian troops to monitor the ceasefire line.[106] In Abkhazia, conflict erupted on August 14, 1992, when Georgian National Guard units entered the region to secure infrastructure amid rising separatist violence, leading to the War in Abkhazia (1992–1993). Abkhaz forces, bolstered by North Caucasian volunteers and tacit Russian support, captured key cities including Sukhumi by September 1993, displacing over 200,000 ethnic Georgians—who comprised about 45% of Abkhazia's pre-war population of roughly 525,000—and resulting in thousands of civilian deaths amid documented atrocities on both sides.[107][34] The conflicts froze after 1993, with Russia maintaining influence through peacekeeping mandates under the Commonwealth of Independent States, though Georgia accused Moscow of bias toward the separatists.[104] Escalation resumed in August 2008 during the Russo-Georgian War, triggered by Georgian artillery strikes on Tskhinvali on August 7–8 in response to separatist shelling, prompting a Russian ground invasion from the north and rapid advances into Georgian territory.[108] The five-day conflict ended with a French-brokered ceasefire on August 12, but Russian forces pushed beyond the regions, occupying buffer zones until partial withdrawal. On August 26, 2008, Russia formally recognized Abkhazia and South Ossetia as independent states, a move echoed by Venezuela, Nicaragua, Nauru, and Syria, but rejected by the United Nations General Assembly and most nations as a violation of Georgia's territorial integrity.[108][109] As of 2025, Abkhazia and South Ossetia function as de facto states with Russian-backed governments, hosting permanent Russian military bases totaling around 7,000 troops, formalized by 2010 defense pacts allowing Russian basing rights in exchange for security guarantees.[110][111] These arrangements have integrated the regions economically and militarily with Russia, including passportization and ruble usage, while restricting Georgia's access and contributing to ongoing displacement, with over 20% of Georgia's territory under Russian occupation.[112] The European Court of Human Rights ruled in 2021 (upheld in appeals) that Russia bears responsibility for human rights violations in the regions since 2008, ordering compensation, underscoring the disputes' persistence amid Georgia's EU and NATO aspirations opposed by Moscow.[110]Broader Ethnic Tensions and Resolutions
In Georgia, the Armenian-populated Samtskhe-Javakheti region has experienced persistent ethnic tensions stemming from demands for greater cultural autonomy, Armenian-language education, and local self-governance, exacerbated by economic underdevelopment and historical grievances from Soviet-era border adjustments.[113] These issues peaked in the early 2000s with protests against Georgian language policies perceived as assimilatory, raising fears of separatism influenced by external actors like Armenia or Russia.[114] Similarly, Georgia's Azerbaijani minority, concentrated in Kvemo Kartli and comprising about 6.5% of the population as of recent censuses, faces integration barriers including limited access to Georgian-language education and political underrepresentation, though intercommunal violence remains rare due to shared economic interests and historical coexistence.[115] The 2020 Nagorno-Karabakh war briefly heightened frictions between Armenian and Azerbaijani communities in Georgia through sporadic clashes, underscoring spillover risks from regional conflicts.[116] In Azerbaijan, Lezgins (approximately 1.7% of the population) and Talysh (0.9%) have voiced grievances over cultural suppression, including restrictions on native-language broadcasting and education, alongside allegations of economic marginalization in northern and southern border areas.[117] Historical Soviet-era assimilation policies have evolved into post-independence state emphasis on Azerbaijani identity, leading to activism among Talysh groups for linguistic rights and against perceived discrimination, as seen in arrests of cultural figures in the 2010s.[118][119] Lezgins, straddling the Azerbaijan-Russia border, have raised concerns about cross-border family separations and cultural erosion, though no organized separatist movements have materialized.[120] Armenians, once a significant minority, were largely displaced following the 1988-1994 Nagorno-Karabakh war and associated pogroms, reducing their presence to negligible numbers and eliminating major intra-state Armenian-Azerbaijani tensions.[117] Armenia hosts smaller minorities such as Yezidis (around 35,000) and Kurds, with occasional reports of socioeconomic exclusion but minimal organized conflict; Azerbaijani communities, numbering over 180,000 in 1989, were expelled or fled amid reciprocal ethnic violence in the late 1980s and early 1990s, leaving virtually none today.[117] Resolution efforts have focused on domestic integration rather than formal treaties. Georgia has implemented bilingual education reforms and infrastructure investments in Javakheti since the mid-2000s, reducing overt protests while fostering economic ties with Armenia to mitigate autonomy demands. Azerbaijan maintains strict state control over minority activism, with limited concessions like Talysh-language media outlets, but international observers note ongoing human rights concerns without escalation to violence.[119] Regional stability is bolstered by Azerbaijan-Georgia economic interdependence, exemplified by joint energy projects, which discourages minority mobilization along ethnic lines.[121] International bodies like the OSCE and EU promote minority rights monitoring and confidence-building, yet broader resolutions remain elusive amid geopolitical rivalries, with no comprehensive inter-state framework addressing these sub-state dynamics as of 2025.[122]Demographics
Population Distribution
The South Caucasus region, encompassing Armenia, Azerbaijan, and Georgia along with disputed territories, has an estimated total population of approximately 17 million as of 2024. Armenia's population stands at around 3 million, Azerbaijan at 10.2 million, and Georgia at 3.9 million, reflecting varied demographic trends influenced by emigration, low birth rates, and recent influxes from conflict zones. Population densities differ markedly: Armenia averages about 100 people per square kilometer across its 29,743 km², Azerbaijan 118 per km² in 86,600 km², and Georgia 56 per km² in 69,700 km², with concentrations higher in fertile lowlands and urban centers.[25][83][123] Urbanization rates are moderate, with 64% of Armenians, 58% of Azerbaijanis, and 61% of Georgians residing in urban areas as of recent estimates, driven by economic opportunities in capitals. Yerevan houses over one-third of Armenia's population (approximately 1.1 million), Baku nearly 25% of Azerbaijan's (about 2.3 million), and Tbilisi around 30% of Georgia's (1.1 million), underscoring heavy reliance on these hubs for services and industry. Rural areas, particularly in mountainous terrains, face depopulation due to outmigration to cities or abroad.[124][125]| Country/Region | Population (2024 est.) | Area (km²) | Density (people/km²) | Urban % |
|---|---|---|---|---|
| Armenia | 3,000,000 | 29,743 | ~101 | 64 |
| Azerbaijan | 10,200,000 | 86,600 | 118 | 58 |
| Georgia | 3,900,000 | 69,700 | ~56 | 61 |
Ethnic and Linguistic Composition
The South Caucasus exhibits significant ethnic homogeneity within its three primary states, shaped by historical migrations, Soviet-era policies, and post-independence conflicts that prompted population displacements. Armenia is overwhelmingly ethnic Armenian, comprising 98.1% of the population as of the 2022 census, with minorities including Yezidis (1.2%), Russians (0.5%), and smaller groups such as Kurds, Assyrians, and Greeks totaling under 1%.[127][128] Azerbaijan features a dominant Azerbaijani (Turkic) majority of 94.8% according to the 2019 census, alongside Lezgins (1.7%), Russians (0.7%), Talysh (0.9%), Avars (0.5%), and Turks (0.4%); the Armenian population has dwindled to negligible levels (effectively 0%) due to mutual expulsions during the Nagorno-Karabakh wars.[117] Georgia's 2014 census records ethnic Georgians (Kartvelians, including subgroups like Mingrelians and Svans) at 86.8%, with Azerbaijanis (6.3%) concentrated in the southeast, Armenians (4.5%) in the south, and smaller minorities including Russians (0.7%), Ossetians (0.4%), and Yezidis (0.3%).[129][130]| Country | Dominant Ethnic Group (% of Population) | Key Minorities |

Religious Affiliations
The South Caucasus exhibits a sharp religious divide, with Armenia and Georgia predominantly Christian and Azerbaijan overwhelmingly Muslim. In Armenia, approximately 92.6% of the population adheres to the Armenian Apostolic Church, which has been the dominant faith since the kingdom's adoption of Christianity as its state religion in 301 CE, with smaller groups including 1% Evangelical Christians and 2.4% other faiths.[17] This Christian majority aligns closely with the ethnic Armenian population, which constitutes 98.1% of residents as of 2025.[127] Azerbaijan, by contrast, is 97.3% Muslim as of 2020 estimates, with Shia Muslims comprising 65% and Sunnis 35%, reflecting the region's historical Safavid-era conversion and subsequent Soviet secularization that tempered overt religiosity.[20][134] Christians, primarily Russian Orthodox and other denominations, account for 2.6%, concentrated among non-Azeri ethnic minorities.[20] In Georgia, Eastern Orthodox Christianity prevails at 83.4%, formalized as the state church and intertwined with national identity since the 4th century CE conversion under King Mirian III.[19] Muslims form 10.7%, mainly among ethnic Azeris in the southeast and Adjarians in the southwest, while Armenian Apostolic adherents (2.9%) cluster in Javakheti and Samtskhe-Javakheti regions.[19]| Country/Region | Dominant Religion | Percentage | Source |
