Melanau
The Melanau were river communities on the Sarawak coast, including Igan and Mukah. Thirteenth-century Chinese records placed Igan, Tutong and Bintulu in the trading realm of Po-ni.
The Nagarakretagama named Malano a Majapahit vassal in 1365. Around 1400 Brunei marched on Igan, remembered as the seat of the chiefs Basiung and Tugau. In 1609 Melanau chiefs joined a revolt from Brunei to Sambas; Brunei reasserted control around 1730.
