The Kalita is an ethnic community or a caste group of Hindus belonging to the state of Assam in North East India. They commonly claim to belong to the Kshatriya caste. There is evidence of Kalita kingdom in very early times as well as during the 15th-16th century.
According to "Purana Tradition", the Kalitas are considered as pure Aryans. Though the Aryan descent theories endorse the arrival of the Kalitas "before the rise of the existing professional castes", the Kalitas generally claim to belong to the Kshatriya caste, and call themselves kulalupta,kula meaning caste and lupta meaning gone ("degraded caste") in the context of the legend that the Kalitas "were Ksatriyas who fled from the wrath of Parasurama who was determined to exterminate the Ksatriyas. But this seems to be a bit of false etymology."
The Kalitas in Assam are considered next only to the Brahmins in the caste-hierarchy. According to the legends, they are "the non-Vedic Aryans" who are responsible for bringing Aryan culture to Assam. Having mingled with local population, they still preserve certain elements of Aryan culture even after localizing their culture to some extent.
Dr. B.S. Guha has found similarities between some surnames of "Alpine Nagar Brahmins" of Gujarat with those of North East India, as referred in the Nidhanpur land grants of Kamarupa King Bhaskaravarman (6th century A.D.) such as "Datta, Dhara, Deva, Nandi, Sena, and Vasu, etc. and connects them with the Kalitas of Assam". Again, historian Kanaklal Barua mentions these surnames while referring to the Nidhanpur inscription and says that these surnames "now belong almost exclusively to the Bengali Kayasthas".
Mirroring the history of Assam, the Kalitas were peasants, though during the rule of the Ahom dynasty they also proved their might and capabilities as soldiers, generals, administrators, envoys, and judges.
