Abdul Momin

Despite initial resistance from Brooke's land expansion, Abdul Momin was forced to negotiate, Brooke eventually obtained land from Kidurong Bay to Baram in 1882, providing an annual payment for the latter. Facing continued losses, Abdul Momin restructured Brunei’s government and eliminated certain taxes in 1884. In 1885, he issued the Amanat, prohibiting further land concessions to foreigners, but it lacked enforcement power. Shortly after, Brunei lost Trusan, exposing the Amanat’s weakness. The British, uninterested in investing in Brunei, allowed Brooke and the British North Borneo Company to dominate, accelerating Brunei’s decline. His efforts ultimately failed, and he died in the same year. Provided by Wikipedia
