Nagaur (N?gaur) is a city in the state of Rajasthan in India. It is the administrative headquarters of Nagaur District. Nagaur lies about midway between Jodhpur and Bikaner. Nagaur or Naga-Pur is referred to in the Mahabharata. The kingdom of Ahichhatrapur which Arjuna is said to have conquered and subsequently offered to his Guru Dronacharya, was perhaps some of the area of the Nagaur district. It was the capital of Jangladesh. The foundation of the city dates back to the 4th century BCE. Nagas originally ruled over this place and from about the 7th century onwards the Chauhans became the overlords of Nagaur and it was included in Sapadalaksha.
