The Kachhwaha (also spelled as Kachwaha and Kachhawaha) is a Rajput clan in India. Some families within the caste did rule a number of kingdoms and princely states, such as Jaipur, Alwar and Maihar.
According to Cynthia Talbot, the meaning of word Kachhwaha is tortoise.
There are many theories on the origin of the Kachhwahas. Pt. Jhabarmal Sharma says that the ancestors of the Kachwahas defeated the Kachappas and assumed the title of "Kachapaghat" (destroyer of the Kachapas). Dr. M.L. Sharma agrees to this theory and says that the Kachwahas were called Kachapaghat for 300 years.
According to Rima Hooja, the Kachhwaha word became popular in the late 16th century during the reign of Raja Man Singh. There are many incriptions and manuscripts which prove this theory, like the ones found in Balvan, Chatsu, Sanganer and Rewasa. Kachwaha generally claim descent from Kusha, a son of the mythological avatar of Vishnu, Rama.
Kachhwaha established their kingdom in Dhundhar region of modern Rajasthan in 11th century. One Kachhwaha King Dulha Rai conquered most of the dhundhar area from Bargurjars. His descendant Raja Pajvan helped Prithviraj Chauhan on his conquest. Kachhwaha Kimg Prithviraj fought alongwith Rana Sanga at battle of Khanwa.
