Hassanal Bolkiah became the Sultan of Brunei Darussalam on 4 October 1967, after his father had abdicated voluntarily.
His coronation was held on 1 August 1968 and thus made him the Yang di-Pertuan (Head of State) of Brunei. Like his father, he has been knighted by Queen Elizabeth II of the United Kingdom, of which Brunei was a protectorate until 1984.

Under Brunei's 1959 constitution, the Sultan is the head of state with full executive authority, including emergency powers since 1962. On 9 March 2006, the Sultan was reported to have amended Brunei's constitution to make himself infallible under Bruneian law. Bolkiah is also the Prime Minister as well as holding the portfolios of Minister of Defence and Finance. As Minister of Defence he is also the Supreme Commander of the Royal Brunei Armed Forces; an Honorary General in the British and Indonesian armed forces and an Honorary Admiral of the Fleet in the British Navy. He appointed himself as Inspector General of Police (IGP) of the Royal Brunei Police Force.

The Sultan's official residence is the Istana Nurul Iman, with 1,888 rooms, 290 bathrooms, and a floor area of 2,152,782 square feet (200,000 m2). The Istana also houses several offices of government, including that of the Office of the Sultan and Yang Di-Pertuan, the Office of the Grand Chamberlain as well as the offices within the Prime Minister's Department. Parts of the Ministry of Defence and Ministry of Finance are also located at the palace.
