Rajopadhyaya also called Newari Brahmin (Nepali: राजोपाध्याय) is the main division of Newar Brahmins in Nepal. The Rajopadhyayas claim to be originated in Kānyakubja or modern day Kannauj, in the north of India (Uttar Pradesh), a city with a prestigious history from where the Bahuns also claim to come. They along with Bahuns claim to be sub-division of Kānyakubja Brāhmins.[1]
In Sanskrit, Rājopādhyāya or Rāj-Upādhyāya literally means 'royal teacher' or 'guru' (Sanskrit: राज = royal + उपाध्याय = guru). Rajopadhyayas, also colloquially called Deva Brāhman or Dyabājyā (God-Grandfather) or Barmu (Brahmin) were the royal gurus and purohits of the Malla kings and their Hindu aristocracy (present day Chatharīyās). Today, the Rajopadhyaya Brahmans are the domestic priests of the high-caste Hindu Newars, principally the Chatharīyas and Śreşțhas, and also certain segments of clean-caste Hindu Newar groups (most notably Bhaktapur Jyapus) of the Kathmandu Valley. In theory, the Chatharīyas of the Kathmandu Valley do not call on other Brahmin group, as Rajopadhyayas alone serve as their historical purohits and perform all their life-cycle Sanskara rituals, including attaining their Gayatri Mantra verse and the sacred thread ('janai') in the Upanayana ceremony. This is opposed to all other clean-caste Newar groups who call upon a Buddhist Vajrāchārya as their family priest to conduct all life-cycle ceremonies.[2]
Rajopadhyayas are an endogamous Brahman group who are the descendants of Kānyakubja Brahmins of Kannauj who immigrated to Kathmandu Valley from 13th to 16th century CE. They are divided among the three cities of Kathmandu, Bhaktapur and Lalitpur into strictly exogamous clans, having three gotras: Gārgya of Lalitpur, Bharadwaja of Bhaktapur, and Kaushik of Kathmandu, all belonging to the Mādhyamdina school of the Shukla Yajurveda, their holy language being Sanskrit, but all well-versed in Newar. As the chief Brahmin group among Newars and as the chief preceptor of the Vedic as well as Tantric knowledge, Rajopadhyayas were placed at top in Nepalese Caste System, and they possess immense social prestige and power, especially among the Hindu Newars.[3]
