Brunei is a small, wealthy sultanate on the island of Borneo in Southeast Asia, its territory split into two parts and surrounded on land by Malaysia, facing the South China Sea. Once the seat of a powerful maritime empire that held sway over much of Borneo and beyond, it shrank over the centuries to its present modest size. Today, thanks to vast reserves of oil and natural gas, it is one of the richest nations in the region, an Islamic absolute monarchy ruled by one of the world's longest-reigning and wealthiest sovereigns.
Brunei rose to prominence as a powerful Islamic sultanate, and at its height in the fifteenth and sixteenth centuries it controlled much of the island of Borneo and parts of the present-day Philippines, growing rich on maritime trade. From the nineteenth century its power waned, as it ceded territory, including the lands that the English adventurer James Brooke carved into his own domain of Sarawak, and others lost to expanding powers. Brunei became a British protectorate, retaining its sultan, and gained full independence in 1984, one of the last states in the region to do so.

Brunei occupies two separate enclaves on the northern coast of Borneo, divided by a sliver of the Malaysian state of Sarawak, with a coastline on the South China Sea. The country is mostly low coastal plain rising to hills and mountains inland, and much of its interior remains covered in dense, well-preserved tropical rainforest, among the best protected in the region. The climate is hot, humid, and rainy, typical of equatorial Borneo, and the rich forests support abundant wildlife, which the small and wealthy state has had the means to conserve.

The flag of Brunei is yellow with two diagonal stripes of white and black across the centre and the national emblem in red in the middle. The yellow is the traditional colour of the sultan, while the white and black stripes represent the kingdom's chief ministers. The central emblem includes a crescent symbolising Islam, a parasol representing the monarchy, and upraised hands, along with a banner bearing the state motto in Arabic, which translates as always in service with God's guidance, reflecting the country's Islamic monarchy.
Islam is the official religion of Brunei and the foundation of its national identity and law, with the sultan as its head, and the majority of the population are Muslim, predominantly Sunni. The country follows an official ideology blending Malay culture, Islam, and the monarchy. There are significant minorities, including Buddhists among the Chinese community and some Christians and followers of indigenous beliefs, but public religious life is firmly Islamic. In recent years Brunei attracted international attention for introducing elements of a strict Islamic penal code.
Bruneian cuisine resembles that of neighbouring Malaysia and the wider region, built on rice, fish, and the abundant produce of the tropics, with halal practice shaping what is eaten. A distinctive national dish is ambuyat, a sticky, starchy paste made from the interior of the sago palm, eaten with a tangy dipping sauce and a special bamboo fork. Rice dishes, noodles, grilled fish and meats, and rich, spiced curries and sauces are common, reflecting Malay, Chinese, and Indian influences in a small but flavourful food culture.
Agriculture plays only a minor role in Brunei's economy, which is dominated overwhelmingly by oil and gas, and the wealthy country imports most of its food. What farming exists produces rice, fruit, vegetables, and poultry, and the government has sought to increase domestic food production for greater self-sufficiency. The vast majority of national income, however, comes from the petroleum and natural gas extracted from onshore and offshore fields, which have funded a high standard of living, free healthcare and education, and the absence of personal income tax.
The golden age of the Brunei sultanate, when it dominated Borneo, and its long decline as it lost territory to James Brooke's Sarawak and to colonial powers, are the great arcs of its history. A British protectorate era preserved the monarchy, and the discovery of oil in the twentieth century transformed the country's fortunes. Full independence came in 1984. Under its long-reigning sultan, Hassanal Bolkiah, Brunei has used its petroleum wealth to build a prosperous welfare state while maintaining an absolute Islamic monarchy.

Brunei has a population of around 450,000 people, the majority ethnic Malays, alongside a substantial Chinese minority and smaller communities of indigenous peoples of Borneo and others. Malay is the official language, English is widely used, and Islam shapes public life. The population enjoys a high standard of living funded by the country's energy wealth, and most people live in the coastal districts, especially in and around the capital, Bandar Seri Begawan. The small, prosperous, and tightly governed nation has one of the highest per capita incomes in the region.
