Agnivansha
According to Bhavishya Purana, When Parshurama destroyed all the Kshatriyas in the land, the Brahmin priests, headed by Sage Vasishtha, kindled a sacrificial fire at Mount Abu and prayed that they be granted protection by being given some warriors. In answer to their prayer, four heroes came out of the sacrificial fire-pit and these were the ancestors of the chief Rajput Clans - the Parmaras, the Pratiharas, the Chauhanas and the Chalukyas.
