The founder of the Sena rule was Samantasena who described himself as a Brahmin-Kshatriya of Karnataka (Karnataka). He himself stated that he fought the outlaws of Karnataka and later turned an ascetic. The inscriptions of the Sena kings mention them as Brahma-Kshatriyas, that is Brahmin by caste and Kshatriya by profession. Also, sources have identified them with the Vaidya (as well as the Ambashtha caste or sub-caste, considered as a mixed caste, being born of Brahmin father and Vaishya mother,) and they married with and were identified with the Bengali Vaidyas (commonly known as Baidyas in Bengal) in Vaidya "Kula-panjikas" (family-tree accounts).
