The southern plains Terai dwellers who are referred as "Marsyā", which is a colloquial corruption of the word Madhesiyā. The Madhesiyā population have a history of being embraced by the Newar population. Historic records show that Maithil Brahmin and Kānyakubja Brahmin were invited by various Malla kings as their royal priests and advisors. It is widely believed that the present Rajopadhyaya Brahmins are the descendants of those immigrant groups. Similarly, Madhesi royal clans including Malla themselves and their courtier castes like Kayastha, Hada, Chauhan, Chandel, Vaidhya, Rajput, etc. migrated into Kathmandu Valley in the 14th century and ruled as Malla kings and their nobility, who have since coalesced to form the current Chatharīya (Kshatriya) caste. Historical records also show trading, service, and untouchable clans of the Indian plains immigrating to Nepal Valley along with the entourage of the Maithil and Malla kings, and in due process, becoming Newars themselves. Some of them includes Dusadh/Podhya, Jogi/Jugi/Kapali, Dhobi/Dhobi, Mali/Mālākar, Halwai/Rajkarnikar, Teli/Manandhar/Sāyami, Kumhar/Kumhā/Prajapati, Chamar/Chyamah, among others.
