Rawatsar is a city, a municipality, and one of the seven tehsils in Hanumangarh district in the Indian state of Rajasthan.

The Bhattis led by Ahmad Khan were defeated at Dabli and the Bikaner Forces erected a fortification known as Fatehgarh.

The Bikaner forces lost against George Thomas of Hissar, who took Fatehgarh in 1799 with the Bhatti.
