A Borneo sultanate once claimed most of the island
Brunei is the only sovereign state lying wholly on Borneo, a small sultanate on the island's northern coast hemmed in by Malaysia's Sarawak, which even splits it in two. With 466,330 people in 2025 it is Asia's least populous country, yet under Sultan Bolkiah it claimed most of Borneo.
That peak came between 1485 and 1528, when Brunei's reach is said to have stretched over Sarawak, Sabah and the Sulu islands. Survivors of Magellan's voyage called in 1521, and in 1578 Spain went to war against it, aiming to seize the capital Kota Batu with help from two Bruneian noblemen. A Spanish traveller that year described a five-storey mosque standing over the water. Local tradition says the founder, landing at the Brunei River estuary around 1400, cried out words that gave the country its name.
Chinese records hint at the older kingdom. A ruler of Boni wrote to the Chinese emperor in 977, and in 1225 the official Zhao Rukuo reported that Boni kept 100 warships to guard its trade. The Javanese poem Nagarakretagama of 1365 lists Barune as a tributary of Majapahit owing camphor each year. In the fifteenth century Boni broke from Majapahit, embraced Islam and became a sultanate, later taking the Meccan emir Sharif Ali as its third sultan.
The empire shrank in the nineteenth century. Brunei handed Kuching to James Brooke, who became the White Rajah, and Sabah to the British North Borneo Chartered Company. It turned into a British protectorate in 1888 and received a British resident in 1906. After Japanese wartime occupation a constitution followed in 1959, and a small revolt against the monarchy in 1962 was crushed with British help.
Sultan Hassanal Bolkiah has reigned since 1967, and the appointed Legislative Council only advises him. The full name, Negara Brunei Darussalam, means country, abode of peace. Oil and natural gas fields underpin the economy, and GDP rose 56 per cent between 1999 and 2008. The House of Bolkiah keeps order partly by funding a generous welfare state for citizens.
