The 1888 Protectorate Agreement and the 1905–1906 Supplementary Treaty between Brunei and the United Kingdom were initially enacted to protect Brunei's territorial sovereignty, particularly from external threats. However, as Brunei's governance evolved to meet modern demands, especially during the adoption of a new constitution, a call to reassess these treaties emerged, particularly from residents of the
Belait District. In response to these developments, the British Resident system, which had dominated Brunei's administration, was abolished. The role of the Resident, once the chief administrator, was downgraded to an advisory position to the sultan of Brunei and the
State Council. This shift officially paved the way for the creation of new roles such as the chief minister and the state secretary, which were essential to modernising Brunei's political structure and adapting to contemporary governance needs. == Functions ==
