Sanggau

Sanggau was a Dayak river state on the Kapuas in western Borneo. Its early Hindu polity was centered on Mengkiang on the Sekayam; local tradition credited its founding to the noblewoman Putri Daranante.

In 1380 the Muslim preacher Abang Abdurrahman married the ruler's daughter, succeeded him and took the title sultan. His son-in-law Sultan Awaluddin moved the court from Mengkiang to Kantu on the Kapuas and built a stone mosque. Around 1400 Brunei's expansion under Awang Alak Betatar brought Sanggau under its overlordship.
