A Nagaraja 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.
Rituals devoted to these supernatural beings have been taking place throughout South Asia for at least two thousand years.
