Defining the North Caucasus12 min read
Unlike the South Caucasus, a geopolitical region comprising three sovereign countries with internationally recognized borders, the North Caucasus poses considerable geographic, geopolitical, historical, ethnographic, and epistemological challenges for those who attempt to define its boundaries. Any attempt to delineate the boundaries of the North Caucasus would inevitably stumble upon questions of where the region begins and ends, which communities belong to it, and which historical experiences give it coherence.
A topographical map could offer several possible clues. The North Caucasus could be construed as the northern slope of the Greater Caucasus ridge. It could refer to the Russian Federation’s ethnic republics from Adyghea to Dagestan. It could stand in for the North Caucasus Federal District (SKFO), created in 2010 under the presidency of Dmitry Medvedev. It could be equated with the agglomeration of the territories where Northwest Caucasian and Northeast Caucasian languages have been spoken natively since the pre-tsarist period. It could also mean the Ciscaucasian military frontier, the mountaineer societies conquered by the Russian Empire, or the Soviet and post-Soviet republics formed in the aftermath of that conquest.
None of these definitions is unsubstantiated. Each one corresponds to a real historical or geographic formation. The difficulty lies in their failure to converge. Administrative borders do not match historical regions. Language families cross state frontiers and intersect with Turkic, Iranic, Kartvelian, Slavic, Germanic, and even Finnic languages. Mountain watersheds do not contain human settlements, much less recent migration, either forced or voluntary. Soviet nationality categories often appropriate older distinctions, distort them, and create new ones all at once. The North Caucasus, therefore, presents a problem of definition because the tools used to define it are varied and mutually contradictory.
The first of these tools is ethnicity itself. The indigenous communities of the North Caucasus are often described through the taxonomy of nationalities: Avars, Dargwas, Chechens, Ingush, Kabardians, Cherkess, Adygeytsy, Qarachays, Malkars, Nogays, Abazas, Ossetians, and others. These ethnonyms correspond to institutions, identities, memories, and political demands. At the same time, they cannot be treated as transparent descriptions of timeless communities. Russian imperial ethnography, military administration, Soviet censuses, passport nationality, autonomous territories, schools, and literary-language policy all helped transform fluid local identities into official ethno-national categories.
A historical analysis of the Soviet policy of nationality-making is helpful in this case. Soviet power did not merely govern nations that already existed in stable form. It organized populations into national categories and then incorporated those categories into the state. The first Soviet census in 1926 played a central role in this process. It assigned individuals to ethno-national categories even where local belonging had often been organized through village, clan, region, estate, religious practice, or political allegiance. A category could precede the national consciousness that it later appeared to record.
The Circassian case shows this process through fragmentation. The broad self-designation Adyghe includes western Circassians, Kabardians, Ubykhs, Shapsugs, Abadzekhs (Abdzakhs), Besleneys, Natukhajs (Natukhays), Bzhedughs, and other related groups. Soviet and Russian classifications divided this broader world into several official nationalities, each associated with particular territories, literary standards, and administrative hierarchies. These divisions were not completely baseless. Kabarda had its own political history; western Circassian communities had their own tribal and regional distinctions; the Black Sea coast and the central Caucasus did not experience Ottoman rule or Russian conquest in identical ways. Soviet nationality policy not only invented new classificatory categories but also converted differences into separate nationality categories and made those categories durable.
Dagestan presents the opposite pattern. In Dagestan, classification has often consolidated smaller communities into larger official nationalities. Andic and Tsezic (Didoic) peoples, as well as Archi and other communities, were incorporated into the Avar nationality. Kaitags and Kubachis were incorporated into the Dargwa (Dargin) nationality. These umbrella identities became real through the education system, literary languages, political representation, and census practice. A person could be Avar in the census, Andi/Dido in social intercourse, attached to a particular village in everyday life, and Dagestani outside the republic. The Soviet state did not erase all local identities, but it required them to pass through a limited number of official taxonomies.
Qarachays (Karachays) and Malkars (Balkars) illustrate yet another pattern, where a closely related Turkic-speaking highland population was divided into two official nationalities and placed within two different dual-titular republics: Qarachays with Circassians (Cherkess), Malkars with Kabardians. Shared language, accounts of ethnogenesis, Alan and Bolgar lineages, oral tradition, mountain settlement patterns, material culture, and older self-designations such as Taulu or Alan did not produce a single administrative homeland. The Stalinist-era deportations revealed the power of these categories in their most violent form. The Qarachays and the Malkars were deported collectively, erased from maps, and later restored within the same divided republican framework. In the Stalinist policy of forced mass population transfers, ethno-national categories were often a mechanism of collective punishment and rehabilitation.
The Nogays raise a different question about the kind of belonging that qualifies a community as North Caucasian. If the term refers to indigenous Caucasian-speaking mountaineer communities, the Nogays stand outside that core. They are a Qypchak Turkic people associated with the Nogai Horde and the Pontic-Caspian steppe. If the term refers to historical and administrative embeddedness in the region, they clearly belong. Nogay communities stretch across Dagestan, Stavropol Krai (Stavropol’e), Karachaevo-Cherkessia, Chechnya, and adjacent territories. The Nogai Steppe itself forms part of the North Caucasian foreland. The Nogay case forces a distinction between the mountain core and the steppe frontier, both of which appear in different definitions of the region. The Qypchak-speaking Kumyks (Qumuqs) also bear less marked similarities to the Nogays in this sense.
The same instability appears in territorial administration. The North Caucasian Federal District seems, by name, to solve the problem. It includes Dagestan, Chechnya, Ingushetia, North Ossetia, Kabardino-Balkaria, Karachaevo-Cherkessia, and Stavropol Krai. Its exclusions are immediately revealing. Adyghea, a Circassian titular republic and an obvious part of the Northwest Caucasus, with the Caucasus Nature Reserve covering part of its territory, belongs to the Southern Federal District. Krasnodar Krai, which contains the Kuban, the Black Sea Circassian coast, Sochi, Tuapse, Anapa, Khosta, Krasnaya Polyana (Gwbaadwy), and central sites of the Russo-Circassian War, also lies outside the district. Rostov-on-Don, long a functional gateway to the region, stands outside but hosts the headquarters of the North Caucasian Railroad.
The inclusion of Stavropol Krai creates the reverse problem. Stavropol Krai is crucial to the administrative history of the North Caucasus, but much of its territory lies in the steppe and semi-desert foreland rather than the Caucasian mountains. It functions as a threshold between the Eastern European Plain, the Ciscaucasian steppe, and the mountain republics. The federal district, therefore, under-reaches and over-reaches at the same time. It excludes historically central western territories and includes a northern foreland zone whose Caucasian character depends on the criterion used. As a result of the transfer of the Shelkovskaya, Naurskaya, and Kargalinskaya districts to the Chechen-Ingush ASSR, finalized in 1962 after the republic’s restoration following the Stalinist deportation of the Chechens and the Ingush, the present territory of the Chechen Republic similarly straddles the same mountain-steppe divide.
Older functional institutions preserve broader geographies. The North Caucasus Railroad, headquartered in Rostov-on-Don, covers Rostov Oblast, Krasnodar Krai, Adyghea, Stavropol Krai, and the republics of Chechnya, Ingushetia, Kabardino-Balkaria, and North Ossetia. Its geography reflects transit infrastructure, imperial administration, military logistics, and economic integration more than the North Caucasus Federal District. The toponym “North Caucasus” here looms larger than the political-administrative unit that now bears the same label.
Dagestan offers a more concentrated example of the mismatch between administrative toponym and territory. The historical Dagestan, the “land of mountains,” referred to the eastern Caucasus mountains and the Caspian littoral: Avaria, Akusha-Dargo, Kaitag, Lakia, Tabasaran, Derbent (Darband), the Samur and Sulak river beds, and local societies. The modern Republic of Dagestan preserves this historical name but not the historically accurate geography. To the south, the republic is too narrow, since Lezgic and Nakh-Dagestani settlements continue into northern Azerbaijan. Lezgins, Tsakhurs, Avars, Rutuls, Mountain Jews, Muslim Tats, and related communities were divided by imperial and Soviet borders. To the north, the republic is too broad, since it includes lowland, steppe, and desert districts tied to Kizlyar, Sarykum, the Terek-Caspian corridor, and the Nogai Steppe.
Cross-border Dagestani communities show the same problem in human terms. Tsakhur settlements linked the upper Samur to Ilisu, Zaqatala, and Qakh. The Elisu Sultanate straddled the crest rather than remaining neatly on one side. Avar communities in Balakan, Zaqatala, Qakh, and Georgia’s Kvareli district demonstrate that Dagestani ethno-linguistic settlements intersect with the borders of Russia, Azerbaijan, and Georgia. “Dagestan” may refer to a republic, a historical mountain-Caspian region, or a wider eastern-Caucasian network where the Shafi madhab of Sunni Islam and the literary use of Quranic Arabic were and continue to be dominant. These delineations overlap without fully converging.
Physical geography is similarly problematic. The Greater Caucasus ridge is the conventional watershed between the North and South Caucasus, but it does not align cleanly with political borders. The historical region of Tusheti is politically part of Georgia, but its waters flow northward through the Andi Koisu and into the Sulak system. The northern part of Khevsureti, especially the Arghuni and Arkhoti valleys, presents a similar ambiguity. Northeastern Azerbaijan also complicates the line. Quba, Qusar, Khachmaz, and the Samur zone lie on the Caspian-facing flank of the Greater Caucasus and drain directly toward the Caspian rather than into the Kura-Aras basin.
The two maritime ends further weaken the mountain-wall model. At the Caspian end, the range descends into the Derbent corridor and the Samur borderlands. The mountains cease to divide in any simple way and open toward a coastal passage between Azerbaijan and Dagestan. At the Black Sea end, the range narrows into the Gelendzhik-Sochi-Gagra littoral, formerly known as the Russian/Soviet Riviera, as the question of geography merges with contested sovereignty. Abkhazia is internationally recognized as part of Georgia, de facto self-governed, militarily controlled by Russia, and linguistically connected to the Northwest Caucasus.
The northern boundary of the North Caucasus is equally unstable. One tradition places the boundary of the Caucasus at the Kuma-Manych Depression, which separates the Eastern European Plain from Ciscaucasia. Another places the Europe-Asia boundary along the crest of the Greater Caucasus ridge. The same territory can therefore appear as part of Europe, part of Asia, or a borderland between the two, depending on the convention chosen. The North Caucasus is, under one scheme, the southern edge of the Eastern European Plain and, under another, the northern slope of a continental divide.
Ethno-linguistics gives the region one of its strongest claims to coherence, but it cannot define the region by itself. Northwest Caucasian and Northeast Caucasian languages anchor the indigenous linguistic core. At the same time, the historical North Caucasus includes Turkic-speaking Karachay-Balkars, Kumyks, Nogays, and Azeris; Iranic-speaking Ossetians, Mountain Jews, and Tats; Slavic and Cossack populations; Armenians; Pontic Greeks; Germans; Estonians; Gagauz, and others. A linguistic definition would either exclude too much or stretch beyond usefulness.
The eastern and western margins are particularly illustrative. Northern Azerbaijan contains a deep Nakh-Dagestani layer: Lezgis across the Samur, Avars and Tsakhurs in the Balakan-Zaqatala-Qakh region, Udi as the clearest surviving link to Caucasian Albania, and small highland communities such as Kryts, Budukh, Khinalug, and Jek, who are native to the Shahdagh region near Quba. Southern Dagestan presents the mirror image: Azeris in Derbent and along the Caspian coast, Tats in coastal villages by the Samur, Shia Lezgis in Miskindzha, and Karabakh Armenian communities in Kizlyar, Derbent, Makhachkala, and Karabakhly (Gharabaghli). The Russo-Azerbaijani border cuts through an older Caspian-Terek contact zone.
The Abazas and the Abkhaz similarly add to the complexities regarding the western and central parts of the Caucasus. The Abaza District in the southern part of Karachaevo-Cherkessia is situated in the North Caucasus, even though the Abazas are culturally intertwined with Circassians and linguistically closest to the Abkhaz. The Kists of the Pankisi Gorge in the Kakheti region of Georgia preserve a Chechen/Vainakh connection south of the Greater Caucasus, while the Batsbi (Tsova-Tush) of Georgia’s Tusheti region preserve an older, endangered Vainakh language embedded in a Georgian Orthodox Tush identity.
The Abkhaz case looms even larger. The Abkhaz and the Circassians are two distinct people groups, but the Abkhaz and the Circassian languages belong to the same Northwest Caucasian language group. Abkhaz belongs to the Abkhaz-Abaza branch; Adyghe and Kabardian belong to the Circassian branch. The Abkhaz are south of the Greater Caucasus ridge, in Abkhazia, but their closest linguistic and kinship ties point toward the Northwest Caucasus.
The Ossetian case works differently than that of the Abkhaz. Ossetian is an Eastern Iranic language, and therefore not Caucasian. The Ossetians’ importance lies in their trans-ridge settlement that bridges the northern and southern slopes of the Greater Caucasus across the Georgian Military Highway, the Daryal Valley, and the Roki Tunnel. Iron and Digor form the main internal linguistic division, while Kudar/Tual Ossetians are best understood as southern Iron-speaking groups shaped by the historical Dvaleti and Samachablo regions, Georgian contact, and more recent “South Ossetian” political history. The North/South divide crisscrosses the Ossetian settlements rather than around them.
The attempt to define the North Caucasus, therefore, ends with a series of mismatches. Ethno-national categories are insufficient because imperial and Soviet institutions reified them. Administrative borders are inadequate because they were often drawn on principles of internal power delegation, security, economic development, and political institutions. Historical toponyms are inaccurate because modern ethno-national territorial entities do not fully converge with the older regions whose toponyms they bear. The Greater Caucasus watershed is imprecise because settlement, rivers, roads, pastures, and polities intersect with it. The Caspian and Black Sea ends are indefinite because the mountain wall turns into a corridor and a littoral. The northern boundary is indeterminate because different geographic traditions place the Caucasus at different continental edges. Ethno-linguistics clarifies the indigenous core, but its continuities extend southward, while the historical region also includes major non-Caucasian-speaking communities.
The North Caucasus remains difficult to define because its borders do not neatly converge: toponyms with communities, communities with languages, languages with territories, territories with states, states with watersheds, watersheds with histories, and histories with administrative maps. This failure of convergence is not a defect in the analysis but a dilemma the region presents to scholarship.
