Rajput clans
Rajput (from Sanskrit "raja-putra", "son of a king") is a large multi-component cluster of castes, kin bodies, and local groups, sharing social status and ideology of genealogical descent originating from the Indian subcontinent. The term Rajput covers various patrilineal clans historically associated with warriorhood: several clans claim Rajput status, although not all claims are universally accepted. According to modern scholars, almost all Rajputs clans originated from peasant or pastoral communities. Lineages. Genealogies of the Rajput clans were fabricated by pastoral nomadic tribes when they became sedentary. In a process called Rajputization, after acquiring political power, they  employed bards to fabricate these lineages which also disassociated them from their original ancestry of cattle-herding or cattle-rustling communities and acquired the name 'Rajput'. There are three basic lineages ("vanshas" or "vamshas") among Rajputs. Each of these lineages is divided into several clans (kula) (total of 36 clans). Suryavanshi denotes descent from the solar deity Surya, Chandravanshi (Somavanshi) from the lunar deity Chandra, and Agnivanshi from the fire deity Agni. The Agnivanshi clans include Parmar, Chaulukya (Solanki), Parihar and Chauhan. Lesser-noted "vansh" include Udayvanshi, Rajvanshi, and Rishivanshi. The histories of the various "vansh"s were later recorded in  documents known as "vamshāavalīis"; André Wink counts these among the "status-legitimizing texts". Beneath the "vansh" division are smaller and smaller subdivisions: "kul", "shakh" ("branch"), "khamp" or "khanp" ("twig"), and "nak" ("twig tip"). Marriages within a "kul" are generally disallowed (with some flexibility for kul-mates of different "gotra" lineages). The "kul" serves as the primary identity for many of the Rajput clans, and each "kul" is protected by a family goddess, the "kuldevi". Lindsey Harlan notes that in some cases, "shakh"s have become powerful enough to be functionally "kul"s in their own right. Suryavanshi (Ikshvaku) lineage of Rajputs. Solar  dynasty or the Ikshvaku dynasty was founded by the King Ikshvaku. The dynasty is also known as ("Solar dynasty" or "Descendants of the Sun"). Shri Ram was also belonged to the Ikshvaku Dynasty, The 21 Tirthankars of Jainism were born in this dynasty. According to Buddhist texts and tradition, Gautama Buddha descended from this dynasty Chandravansh lineage of Rajputs. The Chandravanshi lineage (Somavanshi or Lunar Dynasty) claims descent from Chandra, The lineage is further divided into Yaduvansh dynasty decendents of King Yadu and Puruvansh dynasty decendents of King Puru. Agnivanshi lineage of Rajputs. The Agnivanshi lineage claim descent from Agni , the Hindu god of fire. Battalion (Regiment) Clans of Rajputs. In medieval Indian history, Rajputs made several regiments, special battalions and mercenaries specially during Rajput Era to fight against foreign invaders which consisted of Rajput soldiers from some or all Rajput clans. Their decendents still use those regiment Rajput surnames Purbiya (or Purabia) are Rajput led mercenaries and soldiers from the eastern Gangetic Plain – areas corresponding to present-day western Bihar and eastern Uttar Pradesh.
