Santubong

Santubong was a trading polity at the mouth of the Sarawak River in north-west Borneo. Its port stood beneath Mount Santubong, where imported Chinese ceramics and iron-working remains attest to its trade.

Around 1350, as Majapahit expanded into Borneo, trade declined and the port was abandoned; its people may have moved inland towards Gedong and the Sadong River. The Nagarakretagama recorded the area as Sawaku in 1365. By 1530 Portuguese mapmakers called the bay Cerava and counted it among Borneo's great ports, as Brunei's influence spread.
