The Bruneian empire, just like previous regional empires of Srivijaya, Majapahit, and Malacca, can be considered as a thalassocratic empire that was based upon maritime power, which means its influence was only confined to coastal towns, ports and river estuarines, and seldom penetrated deep into the interior of the island. The Bruneian kings seems to cultivated alliance with regional seafaring peoples of Orang Laut and Bajau that formed their naval armada. The Dayaks, native tribes of interior Borneo however, were not under their control, as its influence seldom penetrated deep into the jungles.
