Chapter 01 · ORIGIN
A province shaped by rivers
Kotawaringin appeared in the 1365 Nagarakretagama, showing that Central Kalimantan’s river ports were connected to wider island politics. The Kahayan, Kapuas and Barito later remained the principal transport corridors because peat swamps and dense forest resisted overland travel. When Central Kalimantan became a province in 1957, its boundaries gathered inland Dayak territories and southern trading towns under Palangka Raya.
