Explanation:

 The Chauhan dynasty flourished from the 8th to 12th centuries. It was one of the four main Rajput dynasties of that era, the others being Pratiharas, Paramaras and Chalukyas. The early branch, founded by Chahamana, ruled at their capital of Ahichhatrapur, in Lat Pradesh in the kingdom of Mahishmati situated on the bank of the river Narmada, and the second branch established its kingdom in the Sambhar area when the power of the Pratihara Rajas weakened.
