Marharajah Churaman (1695 – 20 September 1721) was Zamindar of Sinsini and the head of Jat state of Bharatpur in Rajasthan, India. Instead of Rajputs being the princly rulers, he got a chance to become a Jat ruler after demise of Fateh Singh. He was son of Bhajja Singh and younger brother of Raja Ram Jat. He was the first unanimously elected leader of Jats in 1695. He wanted to make Jats a political power in India for competence against the ruler class "Rajputs".
After the death of Raja Ram(as a participant warrior) in the war of Bijal between Shekhawats and Chauhans on 4 July 1688, old father of Raja Ram, Bhajja Singh became the leader of Jats. Aurangzeb played a trick. He appointed Raja Bishan Singh of Amber as Faujdar of Mathura. Kachwahas were bent upon to subjugate the Jats, who were fighting for freedom from Mughal rule. Bishan Singh gave a written promise to destroy the fort of Sinsini. Mughal and Rajput armies jointly attacked Sinsini and captured it after a war of five months, in the month of January 1690. In this war 200 Mughals and 700 Rajputs were killed against 1500 Jats.
