I am writing a special article on the Coronation of His Majesty Sultan Haji Hassanal Bolkiah. Most Bruneians know the Coronation as the Perpuspaan. This article will be part of Brunei Times special feature on the Coronation this upcoming 1st August 2008. On that day will be the 40th Anniversary of the Coronation.
One of the interesting things I have discovered was that even though the Sultan ascended the throne on 4th October 1967, his title was the Sultan of Brunei Darussalam. Sultan Haji Hassanal Bolkiah became the Sultan and Yang Di-Pertuan of Brunei Darussalam only after the Coronation. Similarly for Raja Isteri, the Raja Isteri's title can only be used after she undergoes a separate Coronation rites at the Palace (the Sultan's traditional Coronation rites was at the Lapau).
There are more interesting things but I will leave that for you to discover in my written article.
