Myanmar, officially the Republic of the Union of Myanmar, covers 676,578 square kilometres on the western side of mainland Southeast Asia. It borders Bangladesh and India to the west and northwest, China to the northeast, and Laos and Thailand to the east and southeast, while its coasts face the Andaman Sea and Bay of Bengal. Nay Pyi Taw is the administrative capital, although Yangon remains the principal commercial metropolis. The country’s physical structure is dominated by north-south ranges and river basins: the Rakhine Yoma rises behind the western coast, the Bago Yoma divides parts of the central lowlands, the Shan Plateau occupies much of the east, and high mountains along the northern frontier culminate at Hkakabo Razi, which official Myanmar sources place at 5,881 metres. Between these uplands, the Ayeyarwady system drains a broad central corridor before spreading across an extensive delta, while the Salween, or Thanlwin, cuts through the eastern highlands toward the Andaman Sea.
Myanmar’s climate is controlled chiefly by the tropical monsoon, but rainfall varies sharply with exposure, elevation and distance from the sea. Roughly 90% of annual precipitation falls during the southwest monsoon from May to October. Coastal Rakhine and Tanintharyi can receive around 5,000 millimetres annually, while the Ayeyarwady Delta generally receives about 2,000–3,000 millimetres; by contrast, parts of the central Dry Zone, sheltered by the Rakhine Yoma, receive less than 760 millimetres. Lowland temperatures are high for much of the year, whereas the Shan Plateau and northern mountains are cooler, especially in winter. These contrasts shape farming calendars and water security. The delta and coastal plains are exposed to monsoon flooding, cyclones and storm surges, while the Dry Zone faces recurrent drought and soil-moisture stress. Climate variability therefore compounds pressure on irrigation, rural livelihoods and disaster-prone settlements, particularly where conflict has weakened maintenance, emergency response and public services.
This climatic gradient supports ecosystems ranging from evergreen and semi-evergreen forests in wetter southern and upland areas to dry deciduous woodland in the central interior, alpine habitats in the far north, mangroves along parts of the coast and extensive wetlands. Myanmar lies within the Indo-Burma biodiversity hotspot and retains some of mainland Southeast Asia’s largest remaining forest landscapes; World Bank data put forest cover at about 42.4% of land area in 2023. Important freshwater systems include Indawgyi Lake in Kachin State and Inle Lake on the Shan Plateau, while coastal mangroves provide fisheries habitat and storm protection. Rice dominates the wetter delta and lowlands, whereas pulses, oilseeds and maize are important in central areas and upland agriculture is more varied. Irrigation from the Ayeyarwady basin and its tributaries supports intensive cultivation, but deforestation, erosion, mining, agricultural expansion and armed conflict have fragmented habitats and complicated conservation in several regions.
Human settlement in the territory of modern Myanmar long predates the modern state. During the first millennium CE, Pyu-speaking urban societies established walled cities in the central dry zone and participated in commercial and religious networks linking South Asia with mainland Southeast Asia; Buddhism became a durable influence, although religious practice remained diverse. From the ninth century, Bamar-speaking populations became increasingly important in the central basin, and the kingdom centred on Bagan unified much of the Ayeyarwady valley between the 11th and 13th centuries. Its Buddhist monuments and irrigation-supported agrarian base left an enduring cultural landscape. After Bagan’s decline, power fragmented among Ava, Hanthawaddy, Shan principalities and other polities before the Toungoo dynasty assembled a large mainland empire in the 16th century. The Konbaung dynasty, founded in the 18th century, again expanded royal authority and fought Siam, Qing China and neighboring powers. British expansion from India then transformed the political geography through three Anglo-Burmese wars in 1824–26, 1852 and 1885, ending the monarchy and bringing the whole country under colonial rule.
British Burma was initially governed as part of British India, and colonial rule reoriented the lower Ayeyarwady Delta toward export rice while teak extraction and port commerce expanded around Rangoon, now Yangon. Migration from British India reshaped urban society, while frontier uplands were administered differently from the Bamar-majority lowlands, reinforcing territorial distinctions that later complicated state-building. Burma became a separate colony in 1937, was occupied by Japan during the Second World War and gained independence on 4 January 1948 after negotiations led by nationalist movements associated with Aung San. The new Union inherited disputes over autonomy, armed communist opposition and conflicts involving several ethnic organizations. A military coup in 1962 introduced authoritarian rule and the “Burmese Way to Socialism”; the 1988 uprising was followed by another military regime, while the 2008 constitution enabled a controlled political opening from 2011 and an elected civilian-led government after 2015. The military seized power again on 1 February 2021. Nationwide resistance and expanding armed conflict followed, and a military-managed election in late 2025 and early 2026 produced a military-backed government in April 2026 without ending the war or restoring broadly accepted civilian rule.
Myanmar’s economy remains shaped by agriculture, natural resources, low-cost manufacturing and services, but conflict, weak institutions and disrupted trade have reversed much of the growth achieved during the 2010s. The currency is the kyat. Rice, pulses, fisheries and other farm products support millions of rural livelihoods; natural gas exported mainly to Thailand and China has long generated foreign exchange, while jade, gemstones and other minerals are important but often linked to opaque or conflict-affected production. Garment manufacturing became a significant urban export industry before the 2021 crisis and still operates under difficult power, logistics and financing conditions. The World Bank estimated that real GDP contracted by 2.0% in fiscal 2025/26 and projected growth of about 2% in 2026/27, but described the outlook as fragile; year-on-year inflation reached 24.6% in April 2026. These figures obscure household conditions marked by high food and transport costs, electricity shortages, displacement, informal employment and restrictions on finance and trade. China and Thailand remain central commercial partners because geography ties Myanmar to their borders, pipelines and transport markets.
Demographic measurement is unusually difficult because conflict prevented a complete national enumeration. The authorities’ provisional 2024 census reported about 51.3 million people, but only roughly 32.2 million were directly counted; another 19.1 million were estimated for areas where enumeration was incomplete or impossible. For comparison, the World Bank’s 2025 population series gives 54.85 million, so the figures should not be treated as like-for-like national counts. The provisional census placed about 31% of the population in urban areas. Settlement remains concentrated in the Ayeyarwady basin, delta and other cultivable lowlands, with Yangon the largest urban and economic centre, Mandalay the principal city of the central interior and Nay Pyi Taw the purpose-built capital. Administratively, Myanmar consists of seven regions, seven states and the Nay Pyi Taw Union Territory, alongside constitutionally designated self-administered areas. These boundaries partly reflect ethnic geography, but citizenship, language, ethnicity and political allegiance do not map neatly onto administrative units.
Myanmar is linguistically and culturally diverse, with Burmese, or Myanmar language, serving as the official language and national lingua franca while many other languages are spoken regionally. Bamar communities predominate across much of the central lowlands, while Shan, Karen, Kachin, Chin, Rakhine, Mon and smaller communities have distinct linguistic and historical traditions; mixed settlement and migration make simple ethnic maps misleading. Theravada Buddhism is the majority religious tradition and has strongly influenced literature, monastic education, architecture and public life, but Christianity is important in parts of Chin, Kachin and Karen areas, while Islam, Hinduism and indigenous traditions also have long-established communities. The Rohingya, a predominantly Muslim community associated especially with northern Rakhine State, have faced systematic restrictions on citizenship and movement and large-scale displacement. Cultural production reflects centuries of interaction with India, China and neighboring Southeast Asia, visible in manuscript traditions, performance, lacquerwork, monastic architecture, colonial urban fabric and modern literature and film.
Myanmar’s transport system follows its geography: the strongest north-south corridors run through the central basin, while mountain chains and conflict make east-west links more difficult. Roads carry most domestic passenger and freight traffic, and the aging metre-gauge railway network connects Yangon with Mandalay, Myitkyina, Mawlamyine and other regional centres but is generally slow. The Ayeyarwady and Chindwin remain important inland transport arteries where roads are weak. Yangon Port, including the inner harbour and Thilawa terminals, is the main maritime gateway; the Myanma Port Authority says the Yangon port system handles more than 85% of normal imports and exports. Yangon, Mandalay and Nay Pyi Taw have the principal international airports. World Bank data recorded electricity access at about 80.4% of the population in 2024, but access does not imply dependable supply: generation shortages, damaged networks and fuel constraints produce frequent outages. Pipelines from the Rakhine coast to China give energy infrastructure a regional role beyond domestic demand.
Myanmar’s regional importance derives from its position between South Asia, China and the rest of mainland Southeast Asia. It belongs to ASEAN and BIMSTEC, shares borders with India and China, and provides China with an overland oil-and-gas connection from the Bay of Bengal to Yunnan. Thailand depends on cross-border commerce and has long imported Myanmar gas, while India sees western Myanmar as a route toward its northeastern states and Southeast Asia. Yet geography that could support corridors, ports and diversified trade is fragmented by civil war, displacement and competing zones of authority. ASEAN’s Five-Point Consensus has made limited progress, while conflict, sanctions, weak public finances, unreliable infrastructure and exposure to cyclones, floods and drought constrain investment and integration. Myanmar’s medium-term weight will therefore depend heavily on whether political authority can become legitimate and predictable enough for its agricultural resources, energy links and transit position to support broader economic recovery and regional connectivity.
