The sultan of Brunei has been on the throne for 52 years, making him the second-longest reigning monarch in the world, after Queen Elizabeth II.

In Brunei – a rather traditional, deeply Muslim Southeast Asian country – the sultan is known for leading a decadent life.

Vanity Fair once dubbed Sultan Hassanal Bolkiah and his brother, Prince Jefri Bolkiah, “constant companions in hedonism.” They spend lavishly on luxury cars, yachts and real estate, and according to the magazine, “allegedly sent emissaries to comb the globe for the sexiest women they could find in order to create a harem the likes of which the world had never known.”

Now, Brunei’s sultan appears to have found religion.
