Brunei, officially Brunei Darussalam, is a sovereign country on the northern coast of the island of Borneo in Southeast Asia. Apart from its coastline on the South China Sea, it is surrounded by the Malaysian state of Sarawak. The country consists of two separate land areas, with the eastern district of Temburong separated from the rest of Brunei by Malaysian territory.[1]

Brunei covers 5,765 square kilometres and has more than 160 kilometres of coastline.[2] Its capital and principal urban centre is Bandar Seri Begawan. The Department of Economic Planning and Statistics estimated the country's population at 458,600 in 2025, of whom 76.7% were Brunei citizens.[3]

Brunei is ruled by Hassanal Bolkiah, the Sultan and Yang di-Pertuan, who also serves as prime minister, minister of defence and minister of finance.[4] The country's political and social framework is strongly influenced by the national philosophy of Melayu Islam Beraja, commonly translated as Malay Islamic Monarchy.[5]

Brunei became a British-protected state in 1888 and regained full sovereignty on 1 January 1984.[6] Soon after independence it joined the Association of Southeast Asian Nations (ASEAN), and it was admitted to the United Nations on 21 September 1984.[7][8]

The discovery of commercial petroleum deposits at Seria in 1929 transformed Brunei's economy. Oil and natural gas remain central to national income, exports and public finances, although the government has pursued economic diversification through downstream energy industries and other sectors.[9]

Name

The country's official name is Brunei Darussalam. The Malay word Darussalam, derived from Arabic, is commonly understood as "abode of peace". Government institutions generally use the full form Negara Brunei Darussalam in Malay and Brunei Darussalam in English.[10]

"Brunei" is the shorter name commonly used internationally and in ordinary English-language references.

History

Early sultanate

Brunei developed into an important Malay sultanate in northern Borneo. Government historical accounts describe the state as a major regional power between the 14th and 16th centuries, with influence extending into parts of present-day Sarawak, Sabah and areas of the southern Philippines.[11]

Islam became a major element of the Bruneian state and its royal institutions. Over succeeding centuries, maritime trade, regional rivalries and European colonial expansion changed the political balance around Borneo.

Territorial decline and British protection

During the 19th century, Brunei lost or ceded substantial territory. Sarawak was ceded to James Brooke in 1841, while the island of Labuan was ceded to Britain in 1846. Brunei and Britain concluded a trade agreement in 1847.[12]

In 1888, Brunei became a British-protected state. Britain assumed responsibility for external affairs while the sultanate retained its internal identity.[13] A British Resident was appointed in 1906. Under the residency system, the resident advised the sultan on most matters other than Malay customs and Islamic religion.[14]

Oil and the twentieth century

Early petroleum exploration took place around Brunei Town and the Belait area, but the decisive commercial discovery was made at the Seria oil field in 1929. Brunei exported oil from the field by 1932.[15] Petroleum income later became one of the foundations of the modern Bruneian state.

Brunei was occupied by Japan during the Second World War from 1941 until 1945.[16]

A written constitution was introduced in 1959, establishing internal self-government while Britain continued to hold responsibility for defence and external affairs.[17][18]

An armed revolt took place in 1962 and was suppressed with British assistance.[19] Brunei subsequently remained outside the new federation of Malaysia.

Sultan Omar Ali Saifuddien III abdicated in 1967 in favour of his son, Hassanal Bolkiah. Hassanal Bolkiah was crowned in 1968.[20]

Independence

Brunei and the United Kingdom signed a Treaty of Friendship and Cooperation in 1979 that prepared the way for the end of the protectorate relationship.[21] Brunei became fully independent on 1 January 1984.[22]

The country joined ASEAN on 7 January 1984.[23] It became a United Nations member on 21 September of the same year.[24]

Geography

Brunei lies on the northwestern side of Borneo, facing the South China Sea. Its land area is 5,765 square kilometres.[25]

The Malaysian state of Sarawak surrounds Brunei on its land borders. Sarawak's Limbang area separates the eastern Temburong District from Brunei's three western districts. The country therefore consists of two physically separated territories.

Much of the interior consists of tropical lowland forest and hilly terrain. The population and much of the country's infrastructure are concentrated closer to the coast and along major river systems. The World Bank reported that forest covered about 72.1% of Brunei's land area in 2023.[26]

Brunei has a humid tropical climate.[27] High temperatures, humidity and rainfall occur throughout much of the year.

Ulu Temburong National Park is among the country's best-known protected rainforest areas and is promoted as a major nature destination.[28]

Administrative divisions

Brunei is divided into four districts:

Each district is administered through a district office under the Ministry of Home Affairs.[29]

The districts are subdivided into mukim, which in turn contain villages or kampung.[30]

Brunei-Muara is by far the most populous district. In 2025 it contained an estimated 332,700 people, or 72.5% of the country's population. Belait had 67,900 residents, Tutong 48,500 and Temburong 9,500.[31]

Government and politics

Brunei is governed under a written constitution whose principal provisions began to take effect in September 1959.[32] The constitution has been amended on several occasions, including amendments that entered into force in 2021 and 2024.[33]

The Sultan is head of state and holds supreme executive authority. Hassanal Bolkiah also serves as prime minister, minister of defence and minister of finance.[34] Constitutional bodies assisting the Sultan include the Privy Council, Council of Succession, Religious Council, Council of Ministers and Legislative Council.[35]

The Legislative Council is composed of appointed members. According to the council's 2026 guidance, it has 34 members, including ex-officio members as well as appointed titled persons, people considered to have achieved distinction and district representatives. Members serve five-year terms.[36]

The national philosophy of Melayu Islam Beraja (MIB), or Malay Islamic Monarchy, connects the monarchy with Malay cultural traditions and Islam and has been officially associated with the state since independence.[37]

Law and judiciary

Brunei has civil and Sharia court systems. The State Judiciary Department administers support services for both the Civil Courts and Syariah Courts, while the two systems retain their respective judicial procedures and legal principles.[38]

The Syariah Courts Act came into force in 2001 and established Syariah subordinate, high and appeal courts.[39]

Brunei also enacted the Syariah Penal Code Order in 2013. Its provisions apply in different ways depending on the offence and, in specified cases, whether the person concerned is Muslim or non-Muslim.[40] Implementation of the code began in stages from 2014, with later provisions coming into effect in 2019.[41]

Foreign relations

Brunei joined ASEAN only days after independence, becoming a member on 7 January 1984.[42] It was admitted to the United Nations on 21 September 1984.[43]

Brunei also participates in a number of regional and international organisations and has developed close relations with other Southeast Asian states. Relations with Singapore include a long-standing Currency Interchangeability Agreement dating from 1967.[44]

Economy

Brunei is a high-income, energy-exporting economy in which hydrocarbons have played a central role for decades. The Petroleum Authority of Brunei Darussalam states that the oil and gas upstream and downstream sectors have dominated the economy for around 90 years.[45]

Commercial oil was discovered at Seria in 1929, with exports beginning in 1932. Brunei Shell Petroleum became the country's largest oil producer and, according to the Petroleum Authority, contributes around 90% of national oil and gas revenues.[46]

The World Bank recorded Brunei's gross domestic product at about US$15.03 billion in 2025, with GDP per capita of approximately US$32,235 and annual real GDP growth of 0.7%.[47]

Economic policy has increasingly emphasised diversification. Investments have been made in downstream petroleum and petrochemical industries as well as other activities intended to broaden the productive base beyond crude oil and natural gas.[48]

The national currency is the Brunei dollar. Brunei and Singapore have maintained a Currency Interchangeability Agreement since 12 June 1967. The arrangement supports the exchange of the Brunei and Singapore dollars at par under the agreed monetary framework.[49]

Demographics

The Department of Economic Planning and Statistics estimated Brunei's population at 458,600 in 2025, an increase of 0.7% from 455,500 in 2024.[50]

In 2025, males represented 53.4% of the population and females 46.6%. Brunei citizens made up 76.7%, permanent residents 5.8% and temporary residents 17.5%. The median age was 32.8 years.[51]

People classified as Malay constituted 73.5% of the population in 2025, while Chinese residents accounted for 9.7% and other groups 16.8%.[52]

Language

Malay is Brunei's official language. English and varieties of Chinese are also used.[53]

Malay has an important role in public administration, national identity and the MIB philosophy. English is widely used in education, commerce and international communication.

Religion

Islam is Brunei's official religion under the constitution, and the Sultan is head of the Islamic faith in the country.[54] The constitution identifies the Shafi'i school of Sunni Islam in connection with the state's official religion while permitting other religions to be practised in peace and harmony.[55]

Christianity, Buddhism and other faiths are also practised in Brunei.[56]

Education

Education is administered primarily through the Ministry of Education, alongside Islamic educational institutions and other specialised bodies.

Universiti Brunei Darussalam (UBD), established in 1985, is the country's oldest university.[57] Its academic and research activities cover subjects including arts and social sciences, business, science, health sciences, education, Asian studies, biodiversity and technology.[58]

The Ministry of Education's Department of Higher Education is responsible for functions including the governance and quality development of higher-education institutions, research capacity and internationalisation.[59]

Health

Brunei has a national public-health system overseen by the Ministry of Health. The country became a member of the World Health Organization on 25 March 1985.[60]

World Bank data placed life expectancy at birth at about 76 years in 2024.[61] WHO data indicate that healthy life expectancy at birth was approximately 67.1 years in 2021.[62]

Culture

Bruneian culture developed within the wider Malay cultural world and has also been shaped by Islam, regional trade and contact with Asian and European societies. The Permanent Mission of Brunei to the United Nations identifies Malay civilisation and Islam as major influences on the country's cultural identity.[63]

The state philosophy of Malay Islamic Monarchy places particular emphasis on Malay language and customs, Islam and the monarchy.[64]

One of the country's best-known cultural landscapes is Kampong Ayer, a large group of settlements built on stilts along the Brunei River at Bandar Seri Begawan. The settlement is connected by waterways, wooden paths and bridges and remains a prominent part of the capital's historical identity.[65]

Major architectural landmarks include the Sultan Omar Ali Saifuddien Mosque in Bandar Seri Begawan and the Jame' Asr Hassanil Bolkiah Mosque.

Tourism

Brunei's tourism sector centres on cultural heritage, Islamic architecture, rainforest environments and river communities. Prominent attractions include the Sultan Omar Ali Saifuddien Mosque, Kampong Ayer and Ulu Temburong National Park.[66]

The Kampong Ayer Cultural and Tourism Gallery was opened in 2009 to present the history and traditions of the water-village communities and to support preservation and sustainable tourism.[67]

International development indicators

The United Nations Development Programme reported a Human Development Index value of 0.837 for Brunei in its Human Development Report data, placing the country in the very-high-human-development group.[68]

In the 2025 Global Knowledge Index, Brunei was ranked 53rd among 195 economies assessed, with comparatively strong performance in areas including pre-university education and institutional enablers for information and communications technology.[69]
