Page "Borneo" Paragraph 19

By the 18th century, the area from Sambas to Berau were tributaries to the Banjar Kingdom, but this eventually shrunk to the size of what is now South Kalimantan as a result of agreements with the Dutch.

In the Karang Intan Agreement during the reign of Prince Nata Dilaga ( Susuhunan Nata Alam ) ( 1808 – 1825 ), the Banjar Kingdom gave up its territories to the Dutch Indies which included Bulungan, Kutai, Pasir, Pagatan and Kotawaringin.

Other territories given up to the Dutch Indies were Landak, Sambas, Sintang and Sukadana.
