Islam in Brunei was first advocated by the 14th century ruler Awang Alak Betatar. He was the first ruler to adopt the religion. Since then Islam went on to extend its influence over Brunei and became an integral part of its life. A synthesis between the indigenous Malay and Islamic cultural forces was achieved with the adoption of the Malay Islamic Monarchy. Brunei religion or Islam has percolated in all aspects of the life of its people.
