In Indian mythology and culture, the Agnivanshi are people descended from Agni, the Vedic god of fire. The Agnivanshi lineage or Agnivansha is one of the three lineages into which the Kshatriya caste of Hindus is divided, the other two races being the Suryavanshi (descended from Surya, the Sun God) and the Chandravanshi (descended from Chandra, the Moon God).

The Agnikunda legend gives an account of the origin of the Agnivanshi Kshatriyas. In fact, it attempts to explain the origin of some of the Rajputs & agnikula kshatriyas of south. There are several versions of the legend.

The Bhavishya Purana version of the legend begins with the puranic legend wherein Parashurama, an avatar of Vishnu, exterminated the traditional kshatriyas of the land. Later, the legend says, sage Vasishta performed a great Yajna or fire-sacrifice, to seek from the gods a provision for the defense of righteousness on earth. In answer to his prayer, a youth arose from the Agnikunda or fire-altar—the first Agnivanshi Rajput. According to different versions of the legend, one or three or four of the Rajput clans originated from the Agnikunda, including Shivaksha(clan of God 'Shiva'and communally known as 'Suryaputra') the Naru Rajputs (Naru means Fire),^{[citation needed]}Gurjara-Pratihara s, Chauhans (Chahamanas), Solankis, Bishts, chaniyas, Dhakars (Dhakad) and Paramaras (Parmars)(Rahevar)(Rever) Agnikula kshatriya

Prithvi Raj III, commonly known as Prithviraj Chauhan (1149–1192 CE), was a king of the Hindu Chauhan (Chauhamana) dynasty, who ruled the kingdom of Ajmer and Delhi in northern India during the latter half of the 12th century.

Prithviraj Chauhan belonged to the Rajput Chauhan clan, which according to a legend mentioned in later manuscripts of Prithviraj Raso was part of Agnivanshi Rajputs, derived its origin from a sacrificial fire-pit. Chauhan was the last independent Hindu king to sit upon the throne of Delhi. He succeeded to the throne in 1169 CE at the age of 20, and ruled from the twin capitals of Ajmer and Delhi which he received from his maternal grandfather Arkpal or Anangpal III of the Tomara dynasty in Delhi. He controlled much of present-day Rajasthan and Haryana, and unified the Rajputs against Muslim invasions. His elopement in 1175 with Samyukta (Sanyogita), the daughter of Jai Chandra Rathod, the Gahadvala king of Kannauj, is a popular romantic tale in India, and is one of the subjects of the Prithviraj Raso, an epic poem composed by Chauhan's court poet and friend, Chand Bardai.
