Among famous figures of the Iban tribe is a brave warrior named Rentap. As it were with other districts in Sarawak, Betong had its own history of opposing the invasion of the British colonials.
The warrior Rentap had fought against the white colonial regime led by Rajah Brooke between 1840-1860 in Layar as well as along Skrang River. In order to hold down the rebellion, The Brooke Regime had built a defense fort named ‘Fort Lily’, which was later used as an administration center in 1858. The Iban rebellion led by Rentap was finally ended when the Brooke Regime had made three massive attacks in year 1857, 1858 and 1861.
