Brunei

At the Bruneian Empire's peak during the reign of Sultan Bolkiah (1485–1528), the state is claimed to have had control over the most of Borneo, including modern-day Sarawak and Sabah, as well as the Sulu archipelago and the islands off the northwestern tip of Borneo. There are also claims to its historical control over Seludong, the site of the modern Philippine capital of Manila, but Southeast Asian scholars believe the name of the location in question is actually in reference to Mount Selurong, in Indonesia.^[16] The maritime state of Brunei was visited by the surviving crew of the Magellan Expedition in 1521, and in 1578 it fought against Spain in the Castilian War.


During the 19th century, the Bruneian Empire began to decline. The Sultanate ceded Sarawak (Kuching) to James Brooke and installed him as the White Rajah, and it ceded Sabah to the British North Borneo Chartered Company. In 1888, Brunei became a British protectorate and was assigned a British resident as colonial manager in 1906. After the Japanese occupation during World War II, a new constitution was written in 1959. In 1962, a small armed rebellion against the monarchy which was indirectly related to the Indonesia–Malaysia confrontation was ended with British assistance and led to the ban of the pro-independent Brunei People's Party. The revolt had also influenced the Sultan's decision not to join the Malaysian Federation while it was being formed. Britain's protectorate over Brunei would eventually end on 1 January 1984, becoming a fully sovereign state.


Brunei has been led by Sultan Hassanal Bolkiah since 1967, and the country's unicameral legislature, the Legislative Council, is simply consultative and are all appointed by the Sultan. The country's wealth derives from its extensive petroleum and natural gas fields. Economic growth during the 1990s and 2000s has transformed Brunei into an industrialised country, with its GDP increasing 56% between 1999 and 2008. The House of Bolkiah maintains political control by providing a welfare state for its citizens, with free or significant subsidies in regards to housing, healthcare and education. It ranks "very high" on the Human Development Index (HDI)—the second-highest among Southeast Asian states after Singapore, which it maintains close relations with including a Currency Interchangeability Agreement. According to the International Monetary Fund (IMF), Brunei is ranked twelfth in the world by gross domestic product per capita at purchasing power parity. Brunei is a member of the United Nations, the World Trade Organization, the East Asia Summit, the Non-Aligned Movement, the Commonwealth of Nations, and ASEAN.
