The Origin of Rajputs
The term Rajput starts coming in use from the 6th Century AD. The origin of the Rajputs is the subject of debate. There are four main streams of thought on origin of Rajputs:
Foreign origin theory of Rajputs
This theory says that the Rajputs are descendents of the races like Sakas, Kushanas, Hunas etc. Dr. VA Smith, Col. James Todd, William Crooks supported this theory. The main argument of James Todd behind the foreign origin of the Rajputs was that these people worshipped Fire and Fire was the main deity of the Sakas and Hunas.
Mixed Origin Theory
This theory as put forward by Dr. DP Chatterjee says that Rajput is a mixed race. Some of them were descendents of the Aryans while some of them were from the foreign races such as Hunas, Sakas etc.
Kashtriya theory of origin
This theory was propounded by Gauri Shankar Ojha and says that the Rajputs are NOT from the foreign origin and they are descendents of the mythological Khatriya Heroes like Rama. The theory divides the Rajput based on their lineage as Suryavanshi & Chandravanshi, which they trace from Surya and Chandra. They worship fire as the Aryans did and worship of fire was not the tradition of the Foreigners only.
This theory comes from the Prithvirajraso of Chandarbardai. According to this theory, Rajputs were the result of Yagya performed by Hrishi Vashistha at “Guru Shikhar” in Mount Abu. The four Rajput clans from Agnikunda are Chauhans, Chalukyas, Parmaras and Pratiharas. Muhnot Nainsi & Suryamal Mishran also support this theory
