History of Rajasthan

Rajasthan, land of princes, comprised many small kingdoms ruled over by clans who warred constantly for supremacy and individually tried to stem the tide of the Islamic invasions. The clans were all Rajputs
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 Hadas of Jhalwawar, Kota & Bundi, the Bhattis of Jaisalmer, the Shekhawats of Shekhawati and the Chauhans of Ajmer.
