It was annexed to Sarawak by Rajah James Brooke, after his victory over the Sekrang and Saribas Iban at the Battle of Beting Maru on 31 July 1849.

The population is culturally mixed, with the majority Iban interacting well with the Malay and Chinese in almost all spheres of activity since the pre-colonial days.

Chinese people are more concentrated at town areas, such as at Betong and Saratok, while some resides at Pusa.

The coastal or riverine region is mainly made up of peat swamp with very limited suitable area for agricultural activities in its natural condition.

Some of the coastal or riverine areas have potential for aquaculture activities such as brackish water fish, tiger prawn and crab cultivation.

People of Betong District can opt for rural shuttle bus service to Saratok, even to neighbouring Sarikei and Sri Aman division.

As for people who wish to travel to upriver areas which are inaccessible by road, they have to use available ferry and boat services.

River transport charges remain high in Betong Division due to the long distance of the upriver areas.

Availability of transports to these areas are limited through bookings at Betong town, using private vans or four-wheel drive vehicles.
