Laos, officially the Lao People’s Democratic Republic, is a landlocked country in mainland Southeast Asia bordered by China, Vietnam, Cambodia, Thailand, and Myanmar. It is the only country in Southeast Asia with no coastline, and its geography, economy, and culture are shaped above all by its position along the Mekong River. Since 1975 it has been governed as a one-party socialist republic under the Lao People’s Revolutionary Party.

Geography of Laos

Laos extends about 1,050 km (650 miles) from northwest to southeast and covers roughly 236,800 square km, according to Encyclopaedia Britannica. Much of the interior is mountainous or made up of high plateaus, including the Xiangkhoang Plateau, home to the Plain of Jars, and the Bolovens Plateau in the south. The Annamese Cordillera runs along much of the border with Vietnam, forming a natural divide between the two countries.

The Mekong River shapes the country almost as much as its mountains do. It forms a long stretch of the western border with Thailand and Myanmar before flowing through Laos itself, carrying much of the country’s transport, its most fertile farmland, and a large share of its hydroelectric potential. The climate is tropical monsoon, with a wet season running roughly from May to October and a drier season the rest of the year, supporting dense forest cover across much of the terrain.

A Brief History of Laos

From Lan Xang to French Rule

Laos’s recorded political history begins in the 14th century, when the ruler Fa Ngum founded Lan Xang (“Land of a Million Elephants”), a kingdom that at its height covered much of present-day Laos and parts of northern Thailand and introduced Theravada Buddhism as the region’s dominant religion, according to Britannica. Lan Xang reached what many historians regard as its golden age under King Souligna Vongsa in the 17th century, but after his death in 1694 the kingdom split into three rival capitals: Luang Prabang, Vientiane, and Champasak.

France absorbed these fragmented Lao territories into French Indochina from the 1890s through the early 1900s, ruling the area as a protectorate with Vientiane as its administrative center. Japanese forces took direct control during the Second World War, and after the war Laos moved through a decade of limited self-rule and armed conflict between French-backed royalists and the Lao Issara independence movement before gaining full independence, confirmed at the 1954 Geneva Conference that ended the First Indochina War, Britannica reports.

Civil War and the Founding of the Lao PDR

Independence did not bring stability. A civil war pitted the Royal Lao Government against the communist Pathet Lao movement, which formed in 1950 with backing from North Vietnam. The conflict became entangled with the wider Vietnam War, as the United States conducted a covert bombing campaign against Pathet Lao and North Vietnamese supply lines inside Laos through the 1960s and early 1970s. The Pathet Lao took full control of the country in 1975, abolished the monarchy, and established the Lao People’s Democratic Republic; an estimated one-tenth of the population fled to Thailand in the aftermath, according to Britannica. The country adopted its current constitution in 1991 and joined the Association of Southeast Asian Nations (ASEAN) in 1997.

Government and Economy

A One-Party Socialist Republic

Laos is a unitary, one-party socialist republic. The Lao People’s Revolutionary Party is the sole legal governing party, its leading role written into the constitution rather than contested through multi-party elections. The National Assembly serves as the legislature, a president acts as head of state, and a prime minister runs the government day to day; in practice, senior party and state leadership overlap closely. This structure has remained largely unchanged since the 1991 constitution formalized the post-1975 political order.

An Economy in Transition

Laos was among the world’s fastest-growing economies in the early 2000s, expanding by an average of around 7 percent a year on the strength of hydropower exports, mining, and capital-intensive infrastructure, according to the World Bank. Growth has slowed sharply since: the World Bank projected growth of 3.7 percent for 2025, while public debt reached an estimated 88 percent of GDP and inflation topped 31 percent in 2023, driven in part by a steep depreciation of the kip. Agriculture, hydropower, mining, and a growing tourism sector remain the backbone of the economy, though labor shortages, fed partly by workers migrating to Thailand for higher wages, and continued underinvestment in health and education weigh on long-term productivity, the World Bank notes.

Culture and People

Ethnic Groups and Language

Laos is ethnically diverse for its size. Lowland Lao, known as Lao Loum, make up roughly two-thirds of the population and live mainly along the Mekong and in the cities; Lao Theung communities such as the Khmu, thought to be among the country’s original inhabitants, account for about a quarter; and Lao Soung groups, including the Hmong, who migrated into northern Laos from the 19th century onward, make up roughly a tenth, according to Britannica. Lao is the official language, though minority communities retain their own languages.

Religion

Theravada Buddhism, practiced largely by the lowland Lao, is the dominant religion, accounting for about half the population, according to Britannica. Roughly two-fifths of Laotians, concentrated among upland ethnic minorities, follow local animist traditions that often blend with Buddhist practice, and small communities of Christians, Muslims, and followers of the Baha’i faith also exist. Buddhist temples, monastic communities, and merit-making festivals remain central to public life, and the state has supported a revival of Buddhist culture since the mid-1970s.

What Laos Is Known For

Internationally, Laos is best known for two UNESCO World Heritage sites that anchor its reputation as a center of traditional Southeast Asian culture and archaeology. The town of Luang Prabang, the former royal capital, was inscribed in 1995 for its fusion of traditional Lao wooden architecture and gilded Buddhist temples with the colonial-era buildings the French added in the 19th and 20th centuries, according to UNESCO. Farther northeast, the Plain of Jars in Xiangkhoang province holds more than 2,100 carved stone jars dating from roughly 500 BCE to 500 CE, the material remains of an Iron Age culture whose full identity and purpose are still not well understood; the site was added to the World Heritage List in 2019.

Laos is also known, more somberly, for the scale of its unexploded ordnance problem. Between 1964 and 1973, forces flew more than half a million bombing missions over Laos and dropped over two million tons of ordnance, including more than 270 million cluster submunitions, as part of the wider conflict in neighboring Vietnam, according to the country’s national UXO clearance program. Up to 30 percent of that ordnance failed to detonate, leaving an estimated 80 million items still in the ground; government-backed clearance teams have destroyed just over 1.8 million of them since 1996.

Why Laos Matters

Laos matters partly because of what its recent history represents: a small, landlocked country whose territory became a Cold War battleground, and which has spent the decades since both rebuilding as a one-party socialist state and clearing the physical debris of that conflict from its soil. Its preserved historic towns and archaeological sites also make it one of mainland Southeast Asia’s clearer windows onto pre-colonial Lao civilization and the older, still only partly understood, Iron Age societies that came before it. And as an active World Bank client country in the Mekong subregion, Laos’s efforts to manage its public debt, expand hydropower exports, and diversify its economy carry weight for how the wider Mekong region balances growth against financial and environmental risk.
