In the medieval period Mandhata Omkareshwar was ruled by the aboriginal Bhil chieftains under the suzerainty of the Parmars of Dhar, the sultans of Malwa , the Scindia of Gwalior , who in turn handed over Mandhata to the British in 1824. The last Bhil chieftain Natthu Bhil fell out with Daryao Gosai a powerful priest of the place. The latter approached the king of Jaipur to set right Natthu Bhil .
The king sent his brother Bharatsingh Chauhan , then Subedar of Jhalarapatan on the border of Malwa . Finally the entire tussle ended with the marriage of Bharatsingh and the only daughter of Natthu Bhil . Bharatsingh along with some of Rajput associates who also married other Bhil girls settled in Mandhata in 1165 A.D. Their progeny is called Bhilalas . Bharatsingh’s descendants ruled Omkareshwar sinch then. During the British rule the Rajas (Officiallly known as Raos) had Mandhata Omkareshwar as their Jagir rights, all abolished now. Baratsingh’s direct descendants are called Rajputs.
