Brunei 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, the country is completely surrounded by the insular Malaysian state of Sarawak. 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. The government is an absolute monarchy under the Sultan, which implements a combination of English common law and sharia law, as well as direct general Islamic practices.

Hassanal Bolkiah (born 15 July 1946) is the 29th and current Sultan and Yang di-Pertuan of Brunei, as well as the Prime Minister of Brunei, making him one of the last absolute monarchs in the world. The eldest son of Sultan Omar Ali Saifuddien III and Raja Isteri (Queen) Pengiran Anak Damit, he succeeded to the throne as the Sultan of Brunei, following the abdication of his father on 5 October 1967.

The sultan has been ranked among the wealthiest individuals in the world. In 2008, Forbes estimated the sultan's total peak net worth at US$20 billion. After Queen Elizabeth II, the sultan is the world's second longest-reigning current monarch. On 5 October 2017, the sultan celebrated his Golden Jubilee to mark the 50th year of his reign on the throne.
