The group denoted by the name Kshatriya or Rājput thus depended on status rather than on descent, and it was therefore possible for foreigners to be introduced into the tribes without any violation of the prejudices of caste, which was then only partially developed. In later times, under Brāhman guidance, the rules of endogamy, exogamy, and _confarreatio_ have been definitely formulated. But as the power of the priesthood increased, it was necessary to disguise this admission of foreigners under a convenient fiction. Hence arose the legend, told in two different forms in _The Annals_, which describes how, by a solemn act of purification or initiation, under the superintendence of one of the ancient Vedic Rishis or inspired saints, the “fire-born” septs were created to help the Brāhmans in repressing Buddhism, Jainism, or other heresies, and in establishing the ancient traditional Hindu social policy, the temporary downfall of which, under the stress of foreign invasions, is carefully concealed in the Hindu sacred literature. This privilege was, we are told, confined to four septs, known as Agnikula, or ‘fire-born’—the Pramār, Parihār, Chālukya or Solanki, and the Chauhān. But there is good reason to believe that the Pramār was the only sept which laid claim to this distinction before the time of the poet Chānd, who flourished in the twelfth century of our era.[i.9] The local tradition in Rājputāna was so vague that in one version of the story Vasishtha, in the other Visvāmitra, is said to have been the officiating priest.
