Agnikula Origin
The theory of Agnikula origin of the Rajputs is given in Prithviraj Raso of Chand Bardai. According
to this Theory, Parsuram, an incarnation of Vishnu, destroyed all the Kshatriyas. However, the
Brahmanas felt the need of warrior class to defend them. They offered prayers to God at top of Mount Abu. A great Havan was performed for about 40 days. The prayers of the Brahmanas brought forth fruit. Form that Agnikund or fire pit, there sprang up four heroes and each one of them created a separate Rajput class. Thus came into existence the Chauhans, the Solankis or Chalukyas, the Parmaars and the Praiharas.

foreigners to be introduced into these tribes without any violation of the prejudices of the caste, which was then only partially developed. But it was necessary to disguise this admission of foreigners under a convenient fiction. Hence, arose the legend, how, by a solemn act of purification or initiation under the superintendence of the ancient Vedic Rishis, the fire born septs Known as Agnikula or fire born - viz., the Parmar, Parihar, Chalukya and Chauhan (Bhaduria, Dhanetiya, Nirvan)."
