Raja Muhkam Singh was a Chieftain and son of Churaman. He succeeded his father to the leadership from c. September, 1721 to 18 November 1722. Fransoo, while giving the genealogy of the Bharatpur rulers, mentions him as the first Raja, who set up his Raj at Thoon (in Bharatpur in modern day Rajasthan, India). It appears, however, that he himself adopted the title of the Raja.[1][non-primary source needed][2]
