According to the Hindu Mythology, the Rajputs of Rajasthan were the descendants of the Kshatriyas or warriors of Vedic India. The emergence of the Rajput warrior clans was in the 6th and 7th centuries. Rajputs ancestry can be divided into two: the "solar" or suryavanshi-those descended from Rama, the hero of the epic Ramayana, and the "lunar" or chandravanshi, who claimed descent from Krishana, the hero of the epic Mahabharata. Later a third clan was added, the agnikula or fire-born, said to have emerged from the flames of a sacrificial fire on Mt Abu.It has been accepted that the Rajputs were divided into thirty-six races and twenty-one kingdoms. The Rajput clans gave rise to dynasties like Sisodias of Mewar (Udaipur), the Kachwahas of Amber (Jaipur), the Rathors of Marwar (Jodhpur & Bikaner), the Harsa of Kota & Bundi, the Bhattis of Jaisalmer and the Chauhans of Ajmer

Rajasthan is the north-western region of India, and has remain independent from the great empires. Buddhism failed to make substantial inroad here; the Mauryan empire (321-184 BC), whose most renowned emperor, Ashoka, Converted to Buddhism in 261 BC, had minimal impact in Rajasthan, However, there are Buddhist caves and stupas (Buddhist Shrines) at Jhalawar, in Southern Rajasthan.Ancient Hindu scriptural epics make reference to sites in present-day Rajasthan. The Holy Pilgrimage site of Pushkar is mentioned in both the Mahabharata and Ramayana.

The fall of the Gupta Empire, which held dominance in northern India for nearly 300 years until the early 5th Century, was followed by a period of instability as various local chieftains sought to gain supremacy. Power rose and fell in northern India. Stability was only restored with the emergence of the Gurjara Partiharas, the earliest of the Rajput (from 'Rajputra', or Sons of Princes) dynasties which were later to hold the balance of power throughout Rajasthan.
The Rajput clans gave rise to dynasties such as the Chauhans, Sisodias, Kachhwahas and Rathores. Chauhans of the Agnikula Race emerged in the 12th century and were renowned for their valour. Their territories included the Sapadalksha kingdom, which encompassed a vast area including present- day Jaipur, Ranthambhore, part of Mewar, the western portion of Bundi district, Ajmer Kishangarh and even, at one time, Delhi. Branches of the Chauhans also ruled territories know as Ananta (in present-day Shekhawati) and Saptasatabhumi.
The Sisodias of the Suryavansa Race, Originally from Gujarat, migrated to Rajasthan in the mid-7th Century and reigned over Mewar, which encompassed Udaipur and Chittorgarh.
The Kachhwahas, originally from Gwalior in Madhya Pradesh, travelled west in the 12th century. They built the massive fort at Amber, and later shifted the capital to Jaipur. Like the Sisodias, they belonged to the Suryavansa Race.
Also belonging to the Suryavansa Race, the Rathore (earlier known as Rastrakutas) traveled from Kanauj, in Uttar Pradesh. Initially they settled in Pali, south of present-day Jodhpur, but later moved to Mandore in 1381 and ruled over Marwar (Jodhpur). Later they started building the stunning Meherangarh (fort) at Jodhpur.
The Bhattis, who belong to the Induvansa Race, driven from their homeland in the Punjab by the Turks, installed themselves at Jaisalmer in 1156. They remained more of less entrenched in their desert Kingdom untill they were integrated into the state of Rajasthan following Independence.
