In Sanskrit, Rajopadhyaya literally means 'the royal teacher or guru' (Sanskrit: राज = royal + उपाध्याय = guru). They were the royal guru during the Malla era and even in Licchavi period. As a Brahman group, they are placed at top in Nepalese Caste System in Kathmandu Valley of Nepal based on Hinduism. They are especially concentrated in the core city area of Kathmandu, Bhaktapur and Lalitpur.
Rajopadhyaya are an endogamous Brahman group, which still celebrates a strong matri-linear traditions. This is perhaps due to their closest link to the female-dominant tantra tradition, which they still adhere. Currently, they debate their identity into following of the three grounds:
- Newar: Many claim Rajopadhyayas are Newars first as they have been into this ethnic group for time immemorial.
- Brahmin: As any other Brahmin group mentioned above, Rajopadhyaya too claim they are only Brahmin first.
- Newar-Brahmin: Some claim Rajopadhyaya as Newar-Brahmin because of their Newari name as Dya (Bhaju) Brahman (alternatively: Dev Brahmin).
Almost all Rajopadhyaya Brahmans claim themselves Hindu or at least the Sanatan Dharm. They adhere mostly to the Shaiva and Shakta cult. Most Rajopadhyaya trace their origin from Kamarupa Kamakshya in Assam, India based on a manuscript found in Bhaktapur mentioning their descent from the Brahman-duo Allasa Raj and Ullasa Raj of 15-16th century.
But they also relate closely to Newar Buddhism of the Vajrayana tradition. Among many Buddhism linkages of this group are: the consecration of a Buddhist vihar in Patan, the religious role in the chariot of Red Macchindranath, similar forms of tantric traditions etc.
