The Dumraon Raj was a feudal principality in the Bhojpur region ruled by the Ujjainiya dynasty.

In Ballia district, Dumraon Raj covered rights of more than 70 villages which are located on the banks of the Ganga river.

[2][3] The royal family of Dumraon is also the main patron of the famous Brahampur fair.

[4] The founders of Dumraon Raj were Ujjainiya Rajputs who traced their origin to the Parmar rulers of Malwa who moved to Western Bihar in the 14th century.

[5] Raja Mukutman Shahi who ascended the throne of Bhojpur in 1601 was highly unpopular amongst his kinsmen and thus he was forced to abdicate in 1607 in favour of his nephew.
