The term "" acquired its present meaning only in the sixteenth century, although it is also used to describe the earlier lineages that emerged in Northern India from sixth century onward. In the eleventh century, the term "Rajaputra" appeared as a non-hereditary designation for royal officials. Gradually, the Rajputs emerged as a powerful social class comprising people from a variety of ethnic and geographical backgrounds. The membership of this class became largely hereditary, although new claims to Rajput status continued to be made in the later centuries. Several Rajput-ruled kingdoms played a significant role in many regions of central and northern India until the twentieth century. Rajput are generally considered to be divided into three primary vansh. Suryavanshi, the Solar dynasty or the Ikshvaku dynasty, denotes descent from the solar deity Surya, the prominent kings and emperors belonging to this royal house are Dilīpa, Raghu, Aja, Dasharatha, Rama, Harishchandra, Sagara, etc.; Chandravanshi from the lunar deity Chandra, the prominent kings and emperors belonging to this royal house are Dushyanta, Bharata, Shantanu, Bhishma, Yudhisthir, Parikshit, etc.; and Agnivanshi from the fire deity Agni. The Rajput population and the former Rajput states are found in north, west, central and east India in the present day state of Rajasthan, Gujarat, Uttar Pradesh, Himachal Pradesh, Haryana, Jammu, Uttarakhand, BiharJharkhand and Madhya Pradesh. According to medieval legends, there are four Agnivanshi clans: Chauhans, Parihars, Parmars and Solankis. It is believed that Parashurama slaughtered Kshatriyas 21 times. The only escapees were those who disguised themselves, those who fled leaving behind their swords and those who fell at his feet. The absence of any warriors led to a Dark Age, where demons increased in number, Vedas came to be trampled under their feet, and Hinduism was forgotten. The sages then visited Parashurama's cave on Mount Abu. There, all the gods, men and nāgas assembled and came up with a plan to destroy the demons. Vashistha erected a fire altar and worshiped Shiva, who appeared before the sages. But the demons disrupted the ceremony by throwing impurities like blood, flesh and garbage on the altar. Twenty sages, including their leader Vashistha, then invoked Brahma and Shiva. They erected a new altar and conducted a fresh ceremony, singing hymns from the Sama Veda. To get rid of these demons, Vashistha performed a homa ritual. This led to the appearance of a hero named Pratihara, who Vashistha placed on the road leading to the palace. After this, another hero named Solanki appeared from the hollowed palm of Brahma. Finally, a third hero appeared, who sage named Pavara. However, these three heroes were not able to stop the demons. Vashistha then dug up a new fire pit, and made yet another offering to the fire, to conjure a new hero. This four-armed hero held a sword, a shield, a bow, and an arrow. Vashistha named him Chahavana or Chauhan, performed his coronation with Vedic hymns, and then ordered him to fight the demons. Parashurama and Shakti blessed the newly created heroes. The sage Bhrigu told him that he would be protected by the goddess Shakti in his endeavours to kill the demons. This, four armed hero warriors defeated the demons. The goddess protected Chohan from all dangers: every time he fell at her feet, his strength doubled and he was able to slay the demons. The goddess came to be known as Ashapuri because she fulfilled the hopes of the sages. The Bachchas is the gotra of Agniwanshi Rajputs. Bachchas and vats are different gotra of Agniwanshi Chauhan Rajput. People of these gotras are the descendants of Prithviraj Chauhan. Most of the people related to these gotras lives in Noida, Haridwar, Bijnor districts of Western Uttar Pradesh, Haryana, Delhi, etc. The vats and bachchas both the gotra comes under Agniwanshi Rajput. Many Bachchas or are said to get the name from queen Bachchal, who was mother of famous folk-deity, Jaharveer Gogaji. Goga was born to queen Bachchal and king Zewar in Dadrewa, the ancient capital of Chauhan Rulers in the Churu district of Rajasthan. According to another legend Gogaji was son of a Chauhan Rajput Ruler named Vacha or Juar, whose wife Bachal was from Tomar/Tuar clan. The apparent reference to parents of Gogaji is same except slight difference in names due to different dialects being spoken those part of Rajasthan and Haryana.
