One of the 15 subgroups under the Bukar-Sadong Bidayuh of Serian, Samarahan is the Sambat group. The Sambats are one of the smaller groups among the Bidayuh.
Like the rest, they came from Tembawang Tampun, and passed through Tembawang Rutoi (the main original Bidayuh settlement for all Bidayuh Bukar-Sadong between the border of Sarawak-Kalimantan), settling at Rawan Mountain. Later on they moved to Tembawang Sambat, between Bukit Bukeng and Mapu Kejabu in the 1600s. They began calling themselves the Sambat Bidayuh. In 1820s, they abandoned the settlement and began migrating to find new ground.
