About Vizier

The Wazir are a group of royal dignitaries within the Sultanate of Brunei whose position ranks the second-highest official in the country behind the Sultan. The Wazir had formerly held the position of the Sultan's highest official in the administration of the then-reigning government throughout Brunei's history, particularly during the times prior to and after the British protectorate. The core of Brunei's nobility consisted of this class of governmental offices, and it consists of a Perdana Wazir, and Wazir Empat under him. Notably, they are sometimes referred to as and acted as Senior Ministers.
