Jharkhand is home to several tribes. They not only differ considerably from the non-tribal population but from one another as well. The most ancient among them are the Mundas, while the Santhals were the last of the tribes to settle in Jharkhand. Unlike the dark brown or almost black complexion of most of the aboriginals, Cheros are light brown and bear Dravidian physiognomy, as they appear to have migrated from the sub-Himalayan tract. Other tribes are Hos, Oraon, Karias, Birhors, Sauria, Paharias, Mal Paharias, Birjias, Asurs, Bhumijs, etc.
