Bangladesh, officially the People’s Republic of Bangladesh, covers 147,570 square kilometres on the northern Bay of Bengal in South Asia. India borders it to the west, north and east, while Myanmar meets the country in the far southeast; its coastline extends for about 580 kilometres. Dhaka, the capital, lies near the centre of a landscape dominated by the lower Ganges-Brahmaputra-Meghna river system. Most territory consists of recent alluvial floodplains and deltaic lowlands built and repeatedly reworked by the Padma, Jamuna and Meghna and their distributaries. Older, slightly raised Pleistocene surfaces form the Barind Tract in the northwest and Madhupur Tract north of Dhaka, while the strongest relief occurs in the Chattogram Hill Tracts and hill systems in Sylhet and along the eastern margin. This low-lying physiography makes rivers simultaneously the principal agents of soil renewal, transport and settlement, and a persistent source of erosion and flood risk.
Climate varies more by season and rainfall regime than by latitude. Bangladesh has a tropical monsoon climate shaped by moist air from the Bay of Bengal, the Himalayan foreland and regional topography. March to May is generally the hottest period, the southwest monsoon dominates roughly June to October, and November to February is cooler and much drier. Rainfall is especially heavy in the northeast around Sylhet and in the southeast, where hills force moist air upward, while western districts are relatively drier and more drought-prone. Monsoon floods are part of the delta’s natural functioning, but damaging river floods, flash floods, waterlogging, riverbank erosion and landslides can accompany extreme rainfall. Coastal districts also face tropical cyclones, storm surges and saline intrusion. Long investment in forecasting, cyclone shelters and evacuation systems has sharply reduced cyclone mortality since 1970, yet climate change is intensifying heat, coastal salinity and flood-related risks where people and productive land are concentrated at low elevation.
Environmental patterns follow the contrast between delta, wetland and hill country. The Sundarbans in the southwest, shared with India, forms the world’s largest mangrove-forest system and supports Bengal tigers, estuarine crocodiles, dolphins and rich aquatic biodiversity; its tidal forests also help buffer coastal settlements from storm surges. Northeastern Bangladesh contains extensive haor wetlands that seasonally expand across the Sylhet Basin, while evergreen and semi-evergreen forests survive in parts of the eastern hills and sal forest occurs on older terraces such as Madhupur. FAO reported in 2023 that legally classified forest land covered 15.58% of national area, although that is not equivalent to intact forest cover. Agriculture is concentrated on fertile floodplains, with rice as the dominant staple alongside jute, vegetables, pulses, tea in the northeast, fisheries and intensive aquaculture. Flood timing, irrigation and dry-season water availability directly shape livelihoods, while erosion, salinity, wetland conversion and habitat fragmentation complicate efforts to increase production without further ecological loss.
The territory of modern Bangladesh occupies the eastern part of the wider historical region of Bengal, whose political geography changed repeatedly long before a Bangladeshi state existed. Ancient centres such as Pundra, Vanga and Samatata participated in networks linking the Gangetic plain, the Bay of Bengal and Southeast Asia, while parts of Bengal came under Mauryan and Gupta influence. Between the eighth and twelfth centuries the Buddhist Pala dynasty made Bengal a major political and intellectual centre, followed in much of the region by the Hindu Sena dynasty. Muslim conquest began around the start of the thirteenth century, but Bengal developed distinctive regional states rather than remaining continuously subordinate to north Indian powers; the independent Bengal Sultanate of the fourteenth to sixteenth centuries deepened commercial links across the Indian Ocean and helped extend Islamic institutions into the countryside. Mughal authority was established progressively from the late sixteenth century, with Dhaka becoming an important provincial and textile-trading centre. European merchants entered this commercial system, but the English East India Company’s victory at Plassey in 1757 and acquisition of revenue rights in 1765 shifted Bengal toward colonial domination.
British rule reorganized Bengal’s administration, landholding and export economy while integrating the delta more tightly with Calcutta. The province’s partition in 1905 and reversal in 1911 foreshadowed the sharper division of 1947, when British India was partitioned and Muslim-majority eastern Bengal became the eastern wing of Pakistan, later called East Pakistan, separated from West Pakistan by more than 1,500 kilometres of Indian territory. Disputes over language, representation and economic power steadily weakened that framework. The Bengali Language Movement culminated in the killings of demonstrators in Dhaka on 21 February 1952; after the Awami League won a majority in Pakistan’s 1970 general election, failure to transfer power and the army crackdown of March 1971 led to a nine-month liberation war and independence in December. Bangladesh adopted a constitution in 1972, but coups and military-dominated governments followed the 1975 political crisis. Parliamentary government returned in 1991. After prolonged two-party rivalry and a long period of Awami League dominance, a mass uprising removed the government in August 2024; an interim administration then oversaw the February 2026 parliamentary election, which returned an elected BNP-led government.
Bangladesh’s economy was transformed by export manufacturing, urbanization and overseas labour migration, although its productive base remains narrower than earlier headline growth rates implied. Ready-made garments are the central export industry: BGMEA recorded apparel exports of about US$38.8 billion in calendar 2025, and World Bank analysis in 2026 described the sector as accounting for nearly 80% of national exports. The European Union and United States remain major clothing markets, while industry depends heavily on imported cotton, machinery, fuel and other inputs. Agriculture still supports large rural populations through rice, fisheries, livestock and higher-value crops, while services, construction, pharmaceuticals, leather goods and remittances broaden domestic demand. Natural gas has long supported power generation and industry, but supply constraints have increased dependence on imported fuels. IMF estimates put real GDP growth at 3.7% in FY2025, down from 4.2% in FY2024, amid political disruption, weak investment and elevated inflation. The central development problem is therefore not simply restoring growth, but creating productive employment, strengthening banks and public revenue, and diversifying exports before trade preferences erode.
The 2022 Population and Housing Census recorded about 169.8 million people, while the World Bank’s 2025 estimate was about 175.7 million, illustrating the difference between a census count and later demographic estimates. UNFPA reported that 32% of the population lived in urban areas in 2022, with growth heavily concentrated in and around Dhaka and Chattogram. Settlement is densest across the central and eastern floodplains, where transport, industry and fertile land overlap; the Chattogram Hill Tracts, Sundarbans and some erosion-prone or seasonally inundated zones are much more sparsely settled. Dhaka dominates administration, finance, higher education and manufacturing, while Chattogram is the main seaport and industrial centre. Other important urban nodes include Gazipur and Narayanganj in the Dhaka industrial belt, Khulna, Rajshahi and Sylhet. The national portal listed eight administrative divisions and 64 districts in August 2026, below which upazilas and union-level institutions provide local administration. Rapid metropolitan expansion has outpaced housing, drainage and transport capacity in several urban areas.
Bangla, or Bengali, is the state language and the principal language of public life, education, literature and mass media, but linguistic identity is more varied than a single-language description suggests. Indigenous communities in the Chattogram Hill Tracts and elsewhere use languages including Chakma, Marma and Tripura varieties, while Urdu remains important within some communities and English is widely used in higher education, business and international affairs. Islam is the religion of the large majority, with Hindus forming the largest religious minority and smaller Buddhist and Christian communities contributing to the country’s social geography. Modern cultural life is deeply shaped by the Bengali language movement and institutions such as Bangla Academy. Literary traditions associated with Rabindranath Tagore and national poet Kazi Nazrul Islam coexist with Baul music, cinema, contemporary art and Jamdani weaving. These traditions reflect centuries of interaction across Bengal rather than culturally isolated national development.
Transport is constrained by the same rivers that make the country fertile, so bridges, ferries and all-weather links have unusually high economic importance. As of August 2026, the Roads and Highways Department’s online inventory lists about 22,737 kilometres of national, regional and zilla highways, while a much larger local-road system connects villages and markets. The Padma Bridge, opened in 2022, created a fixed road link between the southwest and the Dhaka-centred economy; rail investment is also reducing historic breaks between networks east and west of major rivers. Chattogram is the principal maritime gateway, with Mongla serving the southwest, while inland water transport remains essential across the delta. Dhaka’s Hazrat Shahjalal International Airport dominates international aviation, complemented by airports at Chattogram and Sylhet. World Bank data put electricity access at about 99.5% in 2024, but reliable supply, fuel availability and grid quality remain separate issues. Dhaka’s metro has expanded modern mass-transit capacity, although congestion remains a major productivity cost.
Bangladesh’s regional importance comes from the conjunction of population scale, export capacity and geography at the head of the Bay of Bengal. Almost enclosed by India yet also bordering Myanmar, it has a direct stake in South Asian connectivity, Bay of Bengal sea lanes and the stability of western Myanmar. Dhaka hosts the permanent secretariat of BIMSTEC, whose membership links South and Southeast Asia, while Bangladesh also belongs to SAARC, the WTO and the United Nations. The Myanmar frontier has humanitarian as well as strategic weight: UNHCR reported about 1.2 million Rohingya refugees in Bangladesh in 2026, overwhelmingly in Cox’s Bazar and Bhasan Char. The country is scheduled to graduate from the UN least-developed-country category on 24 November 2026, increasing pressure to preserve export competitiveness as some preferences change. Its medium-term position will depend on whether manufacturing experience and improved connectivity can offset climate exposure, fiscal and banking weaknesses, urban congestion, political polarization and pressure to create productive jobs.
