Chauhan, a great Rajput tribe, one of the Agnikulas, and also one of the 36 Royal ruling races. According to the Rajput bards the Chauhan is one of the four Agnikula or 'fire sprung' tribes who were created by the gods in the anali kund or 'fountain of fire' on Mount Abu to fight against the Asuras or demons. Before the seat of their power was moved to Delhi, Ajmer and Sambhar in Jaipur seem to have been their home. After their ejectment from Delhi they are said to have crossed the Jumna to Sambhal in Muradabad, and there still dwell the geneologists and bards of the Chauhan of the Nardak of Karnal and Ambala in which Districts they have retained their dominant position more than elsewhere in the Punjab.

The Chauhans also said to be in Jaipur, and were considered the most valiant of the whole Rajput race, and to them belonged Prithvi Raj Chauhan, the last Hindu Ruler of India. The Chauhans of the Karnal district being closer to Delhi and the Muslim kings started converting to Islam from the 14th to the 17th Century.
