A Nagaraja (Sanskrit: नागराज nāgarāja, lit. 'king of the nagas') is a king of the various races of the nāga, the divine or semi-divine, half-human, half-serpent beings that reside in the netherworld (Patala), and can occasionally take human form.[1] Rituals devoted to these supernatural beings have been taking place throughout South Asia for at least two thousand years.[2]e
