History of Chauhan
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. Chauhan is also one of the 36 (royal) ruling races of the Rajputs.
Chauhan dynasty flourished from the 8th to 12th centuries AD. It was one of the four main Rajput dynasties of that era, the others being Pratiharas, Paramaras and Chalukyas. The Chauhans dominated Delhi, Ajmer, Ranthambhor. They were also prominent at Sirohi in the southwest of Rajputana, and at Bundi and Kota in the east. Inscriptions also associate them with Sambhar, the salt lake area in the Amber (later Jaipur) district. Chauhan politics were largely campaigns against the Chalukyas and the invading Muslim hordes. In the 11th century they founded the city of Ajayameru (Ajmer) in the southern part of their kingdom, and in the 12th century captured Dhilika (the ancient name of Delhi) from the Tomaras and annexed some of their territory along the Yamuna River. Prithviraj III has become famous in folk tales and historical literature as the Chauhan king of Delhi who resisted the Muslim attack in the first Battle of TARAIN (1191). Armies from other Rajput kingdoms, including Mewar assisted him. However, Prithviraj was defeated in a second battle at Tarain the following year. This failure ushered in Muslim rule in North India in the form of the SLAVE DYNASTY, the first of the Delhi Sultanates.
