India covers 3,287,263 square kilometres and occupies most of the South Asian subcontinent, extending from the Himalaya and Karakoram systems to the Indian Ocean. It has de facto land borders with Pakistan, China, Nepal, Bhutan, Bangladesh and Myanmar; India also claims a short boundary with Afghanistan through disputed Kashmir. The Arabian Sea lies to the west, the Bay of Bengal to the east, and Sri Lanka is separated from the southeastern coast by the Palk Strait and Gulf of Mannar. New Delhi is the capital. India’s government revised the measured coastline in 2025 to 11,098.81 kilometres, including island coasts, after higher-resolution mapping. Inland, the country divides into the Himalayan and northeastern mountains, the Indus-Ganga-Brahmaputra plains, the Thar Desert, the Peninsular Plateau and Deccan, the Western and Eastern Ghats, coastal plains, and the Lakshadweep and Andaman and Nicobar island groups. This relief pattern governs rivers, settlement, agriculture and transport.
Climate varies sharply with latitude, elevation, monsoon circulation and distance from the sea. Most of India receives the bulk of its rain from the southwest monsoon between June and September; the India Meteorological Department says roughly three-quarters of annual rainfall falls in the monsoon season. The windward Western Ghats, northeastern hills and Himalayan foothills are very wet, while western Rajasthan, Ladakh and rain-shadow interiors of the Deccan are much drier. Tamil Nadu and adjoining southeastern districts depend unusually heavily on the October-December northeast monsoon. Summers can be intensely hot across northern, central and interior peninsular India, while Himalayan winters bring severe cold and snow; coastal districts have smaller annual temperature ranges but high humidity and cyclone exposure. Climatic variability directly affects crops, reservoirs and groundwater. Heat waves, drought, extreme rainfall, Himalayan landslides, river flooding, cyclones, air pollution and coastal erosion are recurring pressures, while glacier retreat and sea-level rise add longer-term risks.
India spans tropical rain forest, moist and dry deciduous forest, thorn scrub, grassland, desert, alpine meadow, mangrove, wetland and coral ecosystems. The Western Ghats, northeastern India and the Andaman and Nicobar Islands contain especially high concentrations of endemic species, while the Sundarbans form a major mangrove system in the Ganga-Brahmaputra-Meghna delta. The 2023 India State of Forest Report measured forest cover at about 715,343 square kilometres, 21.76% of national geographical area; adding tree cover raised the combined share to 25.17%. Agriculture remains a dominant land use and livelihood base, concentrated in irrigated and rain-fed plains, river valleys and plateau districts. Rice predominates in wetter regions, wheat in much of the north and northwest, while millets, pulses, cotton, sugarcane, oilseeds, tea, coffee and spices occupy distinctive climatic zones. Monsoon dependence, groundwater depletion, soil degradation and fragmented holdings make productivity uneven, linking environmental management directly to rural incomes and food security.
Human occupation reaches deep into prehistory, as the rock shelters of Bhimbetka demonstrate, while the Harappan or Indus civilization created planned cities and long-distance trade networks in the third and second millennia BCE, including Dholavira in present-day Gujarat. Later Vedic societies and expanding agricultural settlements helped reshape northern India, and by the first millennium BCE a field of kingdoms and republics had emerged. The Mauryan Empire in the third century BCE briefly unified much of the subcontinent; Ashoka’s patronage helped Buddhism spread across Asia. Later centuries saw powerful regional formations, including the Gupta state in the north, Chola maritime power in the south and numerous Deccan kingdoms tied to Indian Ocean commerce. From the early second millennium, Turkic and Afghan dynasties based in Delhi connected northern India more closely with Persianate and Islamic political networks. The Mughal Empire, founded in 1526, combined conquest with provincial administration, agrarian taxation and major artistic traditions, though regional powers remained important. European trading companies entered this already commercialized world through coastal enclaves.
The British East India Company converted commercial footholds into territorial power during the eighteenth century, especially after victories in Bengal and the acquisition of revenue rights following the Battle of Buxar in 1764. Company rule expanded through warfare, alliances and annexation, while colonial taxation, land settlements and trade policy reoriented regional economies toward imperial priorities. The uprising of 1857 ended Company government, and the British Crown ruled most of the subcontinent directly or through princely states from 1858. Railways, ports and a centralized bureaucracy integrated territory but also served military control and export commerce. The Indian National Congress, founded in 1885, became a principal vehicle of anti-colonial politics; mass movements led by Mohandas Gandhi broadened participation, alongside socialist, revolutionary, religious and regional currents. British withdrawal in 1947 produced independence and Partition into India and Pakistan, accompanied by mass displacement and communal violence. India became a republic under its Constitution in 1950, built a federal parliamentary system, reorganized many state boundaries linguistically, and later combined electoral democracy with periods of centralization, regional conflict and economic reform.
India now has a large, diversified economy in which services generate the biggest share of output, manufacturing is substantial and agriculture still employs a much larger share of workers than its contribution to GDP. Information technology and business services, finance, construction, pharmaceuticals, automobiles, machinery, electronics, chemicals, textiles and food processing coexist with major coal, iron ore, bauxite and hydrocarbon industries. World Bank estimates indicate real GDP growth accelerated to about 7.6% in FY2025/26 after 6.5% in FY2024/25. Merchandise exports include engineering goods, electronics, refined petroleum products, pharmaceuticals, chemicals, textiles, gems and agricultural products, while crude oil, electronics, machinery and gold are major imports. The United States is the largest merchandise export market, and trade with China, the Gulf, Europe and Southeast Asia is structurally important. Public infrastructure investment and digital systems support growth, but employment quality, informality, uneven human capital, regional inequality and low female participation in paid work remain constraints.
The latest completed national census, in 2011, counted 1.21 billion people; subsequent totals are estimates rather than census counts, and IMF data for 2026 place India at about 1.477 billion inhabitants. Settlement is highly uneven. The Ganga plain, coastal belts, major river valleys and metropolitan-industrial corridors carry very dense populations, while the high Himalaya, desert and forested uplands are much more sparsely settled. Urbanization has continued beyond the 31% recorded in 2011, but strong links between cities and rural districts persist through migration, remittances and commuting. Delhi forms the national political core, while Mumbai is a leading financial and port metropolis; Bengaluru, Hyderabad, Chennai, Kolkata, Ahmedabad and Pune anchor technology, manufacturing, services and trade. Administratively, India is a federal union of 28 states and eight union territories. State boundaries often reflect linguistic and historical identities, but caste, tribe, religion, language, region and class overlap rather than forming a single ethnic map.
India’s linguistic order is both regional and national. Hindi in Devanagari is the official language of the Union, while English continues in Union administration and Parliament under law; the Constitution’s Eighth Schedule recognizes 22 languages, and states use their own official languages. Indo-Aryan languages predominate across much of northern and central India, Dravidian languages across most of the south, while Tibeto-Burman, Austroasiatic and other language families are important in the northeast, Himalayan districts and central-eastern tribal regions. The 2011 census recorded Hinduism as the majority religion and Islam as the largest minority faith, alongside substantial Christian, Sikh, Buddhist and Jain communities and many local traditions. Religious geography reflects centuries of state formation, trade, pilgrimage, conversion and migration. Cultural production is similarly plural: Sanskrit, Tamil, Persian, Urdu and modern regional literatures; Hindustani and Carnatic classical music; Indo-Islamic, Rajput, Dravidian and colonial architecture; textile and craft traditions; and multiple film industries developed through exchange among courts, temples, cities and markets.
Transport and energy networks increasingly bind India’s vast internal market, though quality and access still vary by region. National Highways exceeded 146,500 kilometres in FY2025/26, with high-capacity corridors linking major metropolitan, industrial and port regions, while state and rural roads carry most local movement. Indian Railways remains the backbone of long-distance passenger and bulk freight transport; by March 2025 its communications network alone covered more than 66,800 route-kilometres of optical fibre, reflecting extensive modernization. Maritime trade is distributed among major ports including Deendayal, Mumbai, Jawaharlal Nehru Port, Kochi, Chennai, Visakhapatnam and Paradip, alongside numerous non-major ports and inland waterways. Delhi, Mumbai, Bengaluru, Hyderabad, Chennai and Kolkata are primary aviation gateways within a much larger airport system. Installed electricity generation capacity reached about 484.8 GW by June 2025, with coal still central but solar, wind, hydro and nuclear capacity expanding. Dense digital connectivity contrasts with persistent rural and peri-urban gaps in transport, power quality and public services.
India’s regional weight follows from its scale, geography and economic integration. It dominates South Asia’s landmass and output, sits astride central Indian Ocean sea lanes, borders China and Pakistan, and links the Arabian Sea, Bay of Bengal and Himalayan approaches to Southeast Asia. These positions underpin participation in the United Nations, G20, BRICS, Shanghai Cooperation Organisation, SAARC and BIMSTEC, while making maritime security, border management, energy imports and cross-border connectivity enduring concerns. A large domestic market, expanding manufacturing and services, digital capacity and infrastructure investment give the country growing influence over trade and technology, yet water stress, air pollution, climate extremes, urban congestion, employment creation and unequal state-level development remain structural tests. Demographic scale can support growth only if education, health, jobs and urban systems keep pace. India’s medium-term importance will depend on how effectively a federal, environmentally constrained and highly diverse state converts scale into productive capacity and durable regional connectivity.
