In the 18th century, the West Coast of Borneo Kalimantan was home to a number of small coastal and riverine trading polities, most of them in Muslim Malay hands.
The most important of these was Sukadana [Map 1], which stood in a loose tributary relationship to Banten and controlled much of the Kapuas River trade. This river, over km long, drains an immense territory inhabited mostly by non-Muslim peoples usually called "Dayak. Landak, some distance inland on the river of that name, controlled West Borneo's only source of diamonds. Like Sukadana, Landak was a tributary of Banten. Another riverine kingdom was Sanggau, far inland on the Kapuas ; at the time, the Kapuas was sometimes called the Sanggau River.
Sanggau had deposits of good-quality gold, West Borneo's second most valuable product. Near the coast in the north, Sambas was the most important state ; it was a former tributary of Brunei. Finally, Mempawah, also a coastal state, just north of the Kapuas outlet, was something of a newcomer.

The inland people collected forest products or raised agricultural goods, marketing them through the port. In exchange they acquired imported articles : cloth, iron, tobacco, salt, and the much sought-after large Chinese earthenware jars, called tempayan, from the ruler who controlled the port.
