Kubu

Kubu was a polity on the lower Kapuas river system in western Borneo. Local government histories trace its formation to Syarif Idrus, a migrant from Hadramaut, and a settlement joined by people of several backgrounds. Trade in forest products drew outside merchants, while attacks by maritime raiders encouraged relocation and stronger defences.

The cultural department distinguishes recognition of Idrus as community leader in 1772 from his installation as the first ruler in 1775, with the title Tuan Besar Raja Kubu. Its account places the defensive settlement by the Terentang, a branch of the Kapuas system. The name Kubu is connected in this tradition with defensive works. The sequence gives specific late eighteenth-century context for a riverine trading centre.
