Here's a short story:

Brunei, officially the Nation of Brunei, the Abode of Peace (, Jawi: ), is a sovereign state located on the north coast of the island of Borneo in Southeast Asia. Apart from its coastline with the South China Sea, the country is completely surrounded by the Malaysian state of Sarawak. It is separated into two parts by the Sarawak district of Limbang. Brunei is the only sovereign state completely on the island of Borneo; the remainder of the island's territory is divided between the nations of Malaysia and Indonesia. Brunei's population was in . 

At the peak of the Bruneian Empire, Sultan Bolkiah (reigned 1485–1528) is alleged to have had control over most regions of Borneo, including modern-day Sarawak and Sabah, as well as the Sulu Archipelago off the northeast tip of Borneo, Seludong (modern-day Manila), and the islands off the northwest tip of Borneo. The maritime state was visited by Spain's Magellan Expedition in 1521 and fought against Spain in the 1578 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, in 1959 a new constitution was written. In 1962, a small armed rebellion against the monarchy was ended with the help of the British.
