Hassanal Bolkiah, GCB GCMG (full name: Sultan Haji Hassanal Bolkiah Mu’izzaddin Waddaulah ibni Al-Marhum Sultan Haji Omar Ali Saifuddien Sa’adul Khairi Waddien; born 15 July 1946) is the 29th and current Sultan and Yang Di-Pertuan of Brunei. He is also the first and incumbent Prime Minister of Brunei. The eldest son of Sir Muda Omar Ali Saifuddien III and Rani Isteri Pengiran Anak Damit, he succeeded to the throne as the Sultan of Brunei, following the abdication of his father on 4 October 1967.
The Sultan has been among the wealthiest individuals in the world, with differing estimates of his personal wealth as it is not always evident what can be calculated as personal and what rather as public wealth belonging to the state i.e. crown, as Brunei is a monarchy. Forbes for example estimated the Sultan’s total peak net worth at US$20 billion in 2008.
The Sultan was born on 15 July 1946 in Brunei Town (now called Bandar Seri Begawan) as Pengiran Muda (Prince) Hassanal Bolkiah. The Sultan received high school education at Victoria Institution in Kuala Lumpur, after which he attended the Royal Military Academy Sandhurst in the United Kingdom.
He became the Sultan of Brunei Darussalam on 4 October 1967, after his father abdicated.
His coronation was held on 1 August 1968, and 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.
