🇱🇦 Laos

Linguistic and historical evidence indicates Tai speakers moved from Guangxi into what is now Laos and Thailand between the eighth and tenth centuries. This migration laid the ethnic and linguistic foundation of the later Lao kingdoms.

The Lao alphabet evolved between the thirteenth and fourteenth centuries, derived from the Khmer script. It gave the language a written form contemporaneous with the rise of Lan Xang.

Leading 10,000 Khmer troops, Prince Fa Ngum conquered several principalities in the Mekong River basin and captured Vientiane, tracing his lineage to Khun Borom, and in 1353 founded the Kingdom of Lan Xang, unifying the Lao principalities for the first time. Its name meaning 'land of a million elephants', the kingdom straddled the Mekong valley and adopted Theravada Buddhism as the state religion, giving it a durable religious and political identity. Lan Xang endured as a hub for overland trade before splitting into three rival kingdoms in the early eighteenth century.

Ministers deposed the founder-king and sent him into exile, where he later died. His eldest son succeeded him as Samsenethai and reigned for 43 years, under whom Lan Xang became a regional trade hub.

The death of Samsenethai in 1421 ended a period of commercial ascendancy and plunged Lan Xang into nearly a century of factional competition. The interruption weakened central authority in the Mekong basin.

On ascending the throne, Photisarath relocated the seat of the kingdom to Vientiane to counter the threat of Burmese invasion. The move established Vientiane's long-run primacy as the political centre of the Lao lands.

Setthathirath's reign produced the That Luang stupa, an enduring religious and national monument. His later disappearance during a campaign in Cambodia opened a 70-year period of civil war and Burmese invasions.

Taking the throne in 1637, Sourigna Vongsa extended the kingdom's frontiers in what became a high point of Lan Xang power. His death without an heir led directly to the kingdom's partition.

With no heir to Sourigna Vongsa, the kingdom fragmented into three principalities. The division ended unified Lao statehood for nearly two centuries and left the successor kingdoms vulnerable to Burmese and Siamese domination.

Between 1763 and 1769 Burmese armies conquered northern Laos and absorbed Luang Prabang, while Champasak fell under Siamese suzerainty. The Siamese installed Anouvong as vassal king of Vientiane, completing external control of the Lao kingdoms.

After centuries of gradual decline, the Lao lands came under Siamese (Thai) control from the late 18th century until the late 19th century.

Under Vietnamese pressure, the vassal king of Vientiane rose against Siamese overlordship. The revolt failed: Vientiane was ransacked and Anouvong died a captive in Bangkok, ending Lao political autonomy before the French arrival.

A British observer described the 1876 Siamese military campaign in Laos as transformed into large-scale slave-hunting raids. The episode reflected traditional Southeast Asian warfare's prioritisation of capturing population over holding territory, depleting Lao manpower.

After the Chinese Black Flag Army sacked Luang Prabang, France rescued King Oun Kham and brought Luang Prabang, then Champasak and Vientiane, into its Indochinese protectorate; the 1893 treaty forced Siam to cede territory east of the Mekong and Laos was incorporated into French Indochina alongside Vietnam and Cambodia. Vientiane again became the capital, and French administrators added the terminal 's' to 'Laos' to pluralise the name across the former kingdoms. French colonial rule continued for six decades.

The colony's commodity output remained marginal within French Indochina, never exceeding one per cent of its exports. By 1940 only around 600 French citizens lived in Laos, indicating minimal colonial investment and administrative depth.

The 1907 treaty between France and Siam fixed the boundary that still separates Laos and Thailand.

By 1943 the Vietnamese population reached nearly 40,000 and formed majorities in several towns — 53% of Vientiane, 85% of Thakhek and 62% of Pakse — with the right to elect its own leaders. A 1945 French plan to resettle more Vietnamese on the Vientiane Plain, in Savannakhet and on the Bolaven Plateau was derailed by the Japanese invasion; Martin Stuart-Fox judged the Lao might otherwise have lost control of their own country.

On Japan's surrender some nationalists, including Prince Phetsarath, declared Lao independence. By 1946 French troops had reoccupied the country and conferred autonomy on Laos, deferring rather than settling the sovereignty question.

A nationalist group declared independence on 9 March 1945 with Luang Prabang as capital, but two Japanese battalions occupied the city on 7 April. On 8 April the king, pressed to proclaim independence, instead ended Laos's status as a French protectorate, while secretly sending Prince Kindavong to the Allies and Prince Sisavang to the Japanese.

During the First Indochina War the ICP created the Pathet Lao independence organisation, which fought the French colonial forces with Viet Minh assistance. The movement became the vehicle of Lao communism and the eventual ruling force of the state.

Laos was granted independence within the French Union on 19 July 1949, achieving full sovereignty in 1953.

On 22 October 1953 the Franco-Lao Treaty of Amity and Association ended the French protectorate and Laos became fully independent as the Kingdom of Laos, a constitutional monarchy under King Sisavang Vong. Sovereign statehood was confirmed after the French defeat at Dien Bien Phu and the peace accord for Laos signed at the Geneva Conference of 1954. A civil war between royalist, neutralist and communist factions followed within years.

French defeat at the Battle of Dien Bien Phu ended the First Indochina War and produced the Geneva settlement covering Laos. The accord internationalised the Lao question without resolving the contest between royalists and the Pathet Lao.

Admission on 14 December 1955 came two years after independence, as the kingdom sought international recognition amid deepening Cold War rivalry over Indochina.

A second coalition government was attempted in 1956 to integrate the communists into the royal state. Its failure helped push the country into open civil war by 1959.

From 1958 North Vietnamese forces occupied Lao territory to move men and materiel south against South Vietnam. This drew Laos into the Vietnam War and prompted American aerial and covert intervention.

Fighting broke out between the Royal Lao Army and the Pathet Lao, the latter backed by China, North Vietnam and the Soviet Union, and militarily supported by the People's Army of Vietnam and the Viet Cong; the royal forces were backed by the United States. Between 20,000 and 62,000 Laotians died. The war ended with the communist seizure of power in 1975.

Between 1964 and 1973 the United States conducted the covert, CIA-backed 'Secret War' bombing campaign against Pathet Lao and North Vietnamese positions, aiming to prevent the collapse of the Kingdom of Laos and to deny the Ho Chi Minh Trail to North Vietnamese forces. More than two million tons of ordnance were dropped, nearly as much tonnage as all bombing in the Second World War, making Laos the most heavily bombed country per capita in history. Some 80 million unexploded bombs remain, killing or maiming about 50 people a year.

King Savang Vatthana abdicated on 2 December 1975, ending a six-century monarchy, and the Pathet Lao seized power and proclaimed the Lao People's Democratic Republic, with the communist Lao People's Revolutionary Party taking sole control. The government under Kaysone Phomvihane signed agreements giving Vietnam the right to station troops and appoint advisers overseeing the country, and the deposed king later died in a re-education camp in Vietnam.

A communist newspaper promised in 1977 that the party would pursue American collaborators and their families 'to the last root'. As many as 200,000 Hmong fled into exile in Thailand, some reaching the United States, while other fighters remained hidden in the mountains of Xiangkhouang Province, a remnant emerging from the jungle in 2003.

Sonexay Siphandone joined the leaders of Cambodia, Thailand and Timor-Leste in Hanoi from 7 to 10 June 2026 for the third ASEAN Future Forum. The visit reinforced Laos's close ties with Viet Nam following reciprocal state visits earlier in the year.

Cumulative cargo on the Kunming-Vientiane line passed 80 million tonnes, with daily cross-border services rising to 23 trains a day from two at the line's 2021 opening. The railway has become central to Laos's trade and tourism links with China.

The airport, inaugurated on 6 March 2026, is intended to boost tourism and trade links near the Golden Triangle border area with Thailand and Myanmar.

The IMF executive board considered the staff report on 13 February 2026, finding that reforms had helped stabilise the kip and rebuild reserves even as debt service continued to strain the budget.

The visit followed a state visit to Viet Nam the previous month by Lao party leader Thongloun Sisoulith, continuing a pattern of high-level exchanges between the two neighbouring communist-ruled states.

The 22 February 2026 election filled all 175 seats in a system in which the ruling Lao People's Revolutionary Party is the only legal party. The National Election Committee confirmed the results on 2 March 2026.

The 1 January 2026 groundbreaking forms part of Laos's plan to become the 'battery of Southeast Asia', with a separate 500-kilovolt cross-border line to China also nearing completion. Electricity already accounts for around a fifth of the country's exports.

More than 800 delegates met in Vientiane from 6 to 8 January 2026 and elected a new 73-member Central Committee. The congress adopted a five-year plan targeting average annual growth of at least 6 per cent.

The December 2025 Lao Economic Monitor credited reforms with stabilising the currency and rebuilding reserves, though it warned that high interest payments continued to crowd out social spending.

The 12 November 2025 announcement involved agencies including the FBI and the Drug Enforcement Administration. Lao authorities have separately carried out raids and deportations at the Golden Triangle Special Economic Zone, which has become a hub for cyber-fraud and human trafficking.

Implementation of a BRT system started in 2025 but was put on hold in December 2025 because of organisational complications. The stall illustrated persistent institutional constraints on urban infrastructure delivery.

Arrivals grew from 80,000 international visitors in 1990 to 1.876 million in 2010 and over 5 million in 2024, contributing more than US$1 billion to the economy. By 2010 one in eleven jobs was in tourism, and the European Council on Trade and Tourism named Laos 'World Best Tourist Destination' for 2013.

The 3 December 2021 opening gave landlocked Laos its first modern rail link to China, part of a wider ambition to become 'land-linked' rather than landlocked within the region.

Laos submitted Mattie Do's second feature, Dearest Sister, for Best Foreign Language Film consideration at the 90th Academy Awards. It marked the country's first ever Oscar submission, following international festival recognition for films such as Chanthaly and At the Horizon.

Membership took effect on 2 February 2013 after nearly 15 years of negotiations, requiring Laos to overhaul trade, investment and customs rules as the organisation's 158th member.

Having suffered the world's heaviest per capita bombing, Laos became an advocate of the treaty banning cluster munitions and hosted its inaugural states parties meeting. The role gave the country an unusual measure of diplomatic leadership on a global disarmament issue.

A skull at least 46,000 years old was found in Tam Pa Ling Cave in the Annamite Mountains, then the oldest anatomically modern human fossil in Southeast Asia. Stone artefacts including Hoabinhian types have also been found at Pleistocene sites in northern Laos.

A three-kilometre metre-gauge line connecting southern Vientiane to Thailand was the country's first railway. It was later dwarfed by the 422-km Boten–Vientiane railway to the Chinese border, built under China's Belt and Road Initiative.

Ratification came nine years after Laos signed the treaty. It formally bound the state to international civil and political rights obligations.

Participation in the first East Asia Summit in 2005 extended Lao engagement in wider regional architecture beyond ASEAN. It marked continued diplomatic normalisation.

Congressionally approved legislation normalised bilateral trade in November 2004, reversing decades of commercial estrangement. In 2009 the Obama administration declared Laos no longer a communist state and lifted bans on Lao firms receiving US Export-Import Bank financing.

Laos was admitted alongside Myanmar on 23 July 1997, ending decades of relative isolation and deepening its integration with regional neighbours.

Rural sanitation coverage rose from 8% in 1990 and 10% in 1995 to 38% by 2008, reaching some 1,232,900 additional people. World Bank data in 2014 found Laos had met the Millennium Development Goal targets on water and sanitation, though as of 2018 some 1.9 million people still lacked improved water and 2.4 million improved sanitation.

In 1993 the government reserved a fifth of national territory for conservation preservation, one of the largest proportional commitments in the region. The forests shelter more than 50 mammal species and nearly 300 bird species.

The constitution promulgated on 14 August 1991, and amended in 2003, ostensibly contains safeguards for human rights and can be amended only by the national assembly. Laos was nonetheless classified an authoritarian regime in The Economist's Democracy Index 2016, ranking lowest among the nine ASEAN states surveyed.

Adopted at the party's fourth congress, the reforms permitted private enterprise and foreign investment while the party retained political control. They mirrored reforms under way at the same time in neighbouring Vietnam.

Gun Voice from the Plain of Jars was the first feature-length film made after the abolition of the monarchy, but a censorship board prevented its release. Commercial cinema resumed with Sabaidee Luang Prabang in 2008, and as of 2018 the country had only three cinemas.

At Hanoi's request Laos severed ties with the People's Republic of China in 1979. The result was trade isolation imposed by China, the United States and others, deepening dependence on the Soviet bloc for foreign assistance.

The treaty institutionalised Vietnamese direction of Laotian foreign policy and provided the basis for Vietnamese involvement in Lao political and economic life. By 1979 there were 50,000 PAVN troops and up to 6,000 Vietnamese civilian officials in Laos, 1,000 of them attached to ministries in Vientiane.
