Kazakhstan covers 2,724,900 square kilometres across central Eurasia, making the Republic of Kazakhstan the world’s largest landlocked country and the ninth largest state by area. Russia borders it to the north and west, China to the east, and Kyrgyzstan, Uzbekistan and Turkmenistan to the south, while its western edge reaches the enclosed Caspian Sea. Astana, the capital, stands on the Ishim River in the northern steppe. The landscape changes from the Caspian Depression and Ustyurt Plateau in the west through the deserts of the Turan Lowland and the central Kazakh Uplands, or Saryarka, to the Altai, Zhetysu Alatau and Tien Shan along the east and southeast. Northern Kazakhstan grades into the West Siberian Plain. Lake Balkhash and the remnants of the Aral Sea occupy major internal basins, while the Irtysh, Syr Darya, Ili and Ural are principal rivers. Khan Tengri rises to 6,995 metres on the southeastern frontier, contrasting sharply with the country’s low arid basins.
Distance from the world ocean gives Kazakhstan a sharply continental climate, but latitude and elevation create strong regional contrasts. Kazhydromet records about 320–360 millimetres of annual precipitation in the northern forest-steppe and 230–340 millimetres across the steppe; semi-desert districts can receive as little as about 134 millimetres. Winters are severe in the north and east, where temperatures can fall below −40°C, while summer heat can exceed 40°C in the south and interior. Mountain belts are cooler and wetter, storing snow and glacier ice that feed rivers used downstream. Drought, dust storms and wind erosion affect drylands, whereas rapid spring snowmelt and ice jams can trigger major northern floods. Warming is altering snow and glacier regimes and increasing uncertainty over runoff. Because important rivers cross borders, water stress is also a foreign-policy issue, while contraction of the Aral Sea remains the clearest legacy of unsustainable regional water diversion.
Ecologically, Kazakhstan forms a broad transition from northern grassland to extreme aridity, interrupted by wetlands and mountain refuges. Government summaries classify about 44% of the country as desert, 14% as semi-desert and 26% as steppe, with forests occupying about 5%. Northern chernozem and chestnut soils support rain-fed wheat, barley and oilseeds; farther south, irrigation along the Syr Darya, Ili, Chu and other rivers sustains cotton, rice, fruit and vegetables. Sheep, cattle and horse grazing remain important across steppe and semi-desert rangelands. Wetlands have exceptional biological value within this dry interior. The UNESCO-listed Saryarka – Steppe and Lakes of Northern Kazakhstan protects 450,344 hectares in the Korgalzhyn and Naurzum reserves, including freshwater and saline lakes used by immense numbers of migratory waterbirds. Habitat fragmentation, overgrazing in some areas, desertification and pressure on river flows therefore connect biodiversity conservation directly with agricultural productivity and water management.
The territory of modern Kazakhstan has long linked mobile societies of the Eurasian steppe with the irrigated and urban worlds of Central Asia. Bronze and Iron Age pastoral cultures were followed by groups conventionally described as Saka or Scythian, whose economies combined herding, warfare and long-distance exchange. From the first millennium CE, Turkic-speaking states increasingly shaped the steppe, while southern centres such as Taraz and Otrar became nodes on Silk Roads routes connecting Transoxiana, China and the wider Eurasian interior. Islam spread gradually through these commercial and political networks. The Mongol conquests of the early thirteenth century reordered the region, placing much of present-day Kazakhstan within the domains of Jochi and the Golden Horde or related successor states. In the fifteenth century, Kerei and Janibek led groups that formed the Kazakh Khanate, traditionally dated to the 1460s. Its boundaries did not match those of the modern republic, but it consolidated political communities central to Kazakh identity. Dzungar pressure in the seventeenth and early eighteenth centuries weakened the steppe polities and encouraged some Kazakh rulers to seek Russian protection.
Russian suzerainty developed into imperial conquest and administrative incorporation during the eighteenth and nineteenth centuries. The empire dismantled khanal authority, built military lines and encouraged settler agriculture, restricting pastoral mobility and altering landholding in the north. Resistance included repeated uprisings and the wider Central Asian revolt of 1916; after the Russian Revolution, the Alash movement sought autonomy before Bolshevik rule prevailed. Kazakhstan became a Soviet autonomous republic and, in 1936, a union republic. Forced collectivization and sedentarization helped produce the catastrophic famine of the early 1930s, while industrialization, deportations and the Gulag system reshaped demographic geography. The Virgin Lands campaign from 1954 converted vast northern grasslands to grain farming; Semipalatinsk became a nuclear-test region and Baikonur a centre of the Soviet space programme. Sovereignty followed on 16 December 1991. Market reform and petroleum development transformed state finances, but political power remained highly centralized. Reforms accelerated after the January 2022 unrest. A constitution approved by referendum on 15 March 2026 and effective from 1 July replaced the bicameral Parliament with a 145-seat unicameral Kurultai while retaining a unitary presidential system.
Hydrocarbons, minerals and metals remain the foundation of Kazakhstan’s export economy, although services generate most domestic output. Tengiz, Kashagan and Karachaganak anchor oil and gas production, while uranium, coal, copper, zinc and ferroalloys support mining and processing; northern grain is another important export. Preliminary national accounts show real GDP growth of 6.5% in 2025, with services contributing 57.6% of GDP and goods-producing sectors 36.6%. That acceleration reflected strong demand and higher oil output rather than a decisive move away from commodity dependence. Crude oil alone accounted for 52.3% of merchandise exports in January–March 2025, exposing national income to energy prices and disruptions along external routes. The European Union, China and Russia are central commercial partners, while Eurasian Economic Union membership sustains dense supply-chain links with Russia. Diversification policy emphasizes petrochemicals, manufacturing, agribusiness, logistics, digital services and renewable energy, but inflationary pressure, productivity gaps, state influence and strong regional disparities complicate the translation of macroeconomic growth into evenly distributed living standards.
The 2021 census counted 19,186,015 people; the Bureau of National Statistics estimated 20,590,589 residents on 1 July 2026, including 13.19 million urban and 7.40 million rural inhabitants. Average density is only about 7.6 people per square kilometre, but settlement is highly uneven. The south and southeast are much denser because irrigated agriculture, old trading cities and milder conditions supported long-established population centres, while oil and mining created separate concentrations in the west and centre. Almaty remained the largest city at about 2.37 million residents in July 2026, ahead of Astana at 1.68 million and Shymkent at 1.31 million. Kazakhstan is divided into 17 regions and three cities of republican significance: Astana, Almaty and Shymkent. Ethnicity is distinct from citizenship: the 2021 census recorded ethnic Kazakhs at 70.4%, Russians at 15.5% and Uzbeks at 3.2%, alongside Ukrainians, Uyghurs, Germans, Tatars, Koreans and smaller communities shaped by imperial, Soviet and post-independence migration.
Language and religion reflect the same historical layering. Under the constitution effective from July 2026, Kazakh is the state language, while Russian is officially used on an equal basis in state organizations and local self-government. Kazakh has expanded in administration, education and media since independence; Russian remains widely used in cities, business and interethnic communication, with bilingualism common but uneven. Most ethnic Kazakhs and several other Central Asian communities are predominantly Sunni Muslim, while Russian Orthodoxy is the largest Christian tradition; the state is constitutionally secular, and religion does not map neatly onto ethnicity or language. Cultural life combines pastoral and urban inheritances. The dombra and instrumental küi repertoire emerged from steppe musical culture, while oral poetry and epic performance carried historical memory across mobile communities. Abai Qunanbaiuly helped define modern Kazakh literary and philosophical language in the nineteenth century, and Mukhtar Auezov became a major twentieth-century novelist. Southern Islamic architecture, Soviet modernism, contemporary cinema and multilingual publishing add further layers.
Kazakhstan’s size makes transport and energy infrastructure both a costly necessity and a source of regional influence. Railways carry minerals, grain and containers between industrial regions and the borders with Russia and China; national statistics recorded about 466.7 million tonnes of rail freight in 2025. The Dostyk and Altynkol crossings connect with China, while Aktau and Kuryk on the Caspian link rail cargo to Azerbaijan and the South Caucasus through the Trans-Caspian, or Middle Corridor. Almaty and Astana are the principal air gateways, supported by regional airports. Pipelines connect western oil and gas fields with Russia, China and domestic markets, so export-route reliability directly affects trade and public revenue. Electricity still depends heavily on coal-fired generation in the north, supplemented by gas, hydropower and expanding wind and solar capacity. Vast distances and sparse rural settlement make roads, transmission lines and municipal utilities expensive to maintain, and infrastructure quality remains more uneven outside large cities, industrial districts and resource-producing regions.
Kazakhstan’s regional importance derives from its scale, resource wealth and location between Russia, China, the Caspian basin and the rest of Central Asia. It belongs to the Eurasian Economic Union and Collective Security Treaty Organization, helped found the Shanghai Cooperation Organisation, and participates in the OSCE while maintaining substantial relations with the European Union, Turkey and the United States. The Middle Corridor adds Caspian access toward the South Caucasus and Europe, but Russia remains essential to many trade and energy routes and China is a major market and infrastructure partner. The same geography creates constraints: hydrocarbon dependence and limited export corridors increase exposure to external shocks; shared rivers require sustained cooperation with neighbours; climate change intensifies drought, flood and glacier risks; and low density raises infrastructure costs. Kazakhstan’s medium-term position will depend on whether constitutional restructuring, transit investment and economic diversification can turn resource and location advantages into broader productivity while containing water stress and regional inequality.
