According to tradition, the original Raja of Dhalbhum was Chintamoni Dhoba, a person of washerman caste. The pai or grain measure used in these parganas was for a long time called Chintaman pai. Legend goes on to say that Dhalbhum was wrested from him by Jagannath Deb of Dholpur in Rajputana. After 32 generations Supur Raj, as it was locally called, was divided in consequence of a disputed succession. One of the successors continued at Supur and the other shifted to Ambikanagar. Both the families were related to the families of Bishnupur, Raipur, Shyamsundarpur and others.They ruled for about 700 years. A branch of the same family ruled in Chikligarh or Jamboni.
Rankini Devi is established as the family goddess of the Dhalbhum rulers. It is said that human sacrifice was offered to the goddess every year,
