Brunei Darussalam, officially the State of Brunei, Abode of Peace, is a country located on the north coast of the island of Borneo, in Southeast Asia. Apart from its coastline with the South China Sea it is completely surrounded by the state of Sarawak, Malaysia, and in fact it is separated into two parts by Limbang, which is part of Sarawak.

The Sultanate of Brunei was very powerful from the fourteenth to the sixteenth century. Its realm extended over the coastal regions of modern-day Sarawak and Sabah, the Sulu archipelago, and the islands off the northwest tip of Borneo. European influence gradually brought an end to this regional power. Later, there was a brief war with Spain, in which Brunei's capital was occupied. Eventually the sultanate was victorious but lost territories to Spain. The decline of the Bruneian Empire culminated in the nineteenth century when Brunei lost much of its territory to the White Rajahs of Sarawak, resulting in its current small landmass and separation into two parts. Brunei was a British protectorate from 1888 to 1984.
