Nambudiri
Nambudiri mythology associates their immigration to Kerala from the banks of Narmada, Krishna, Kaveri rivers with the legendary creation of Kerala by Parasurama, the 6th avatar of Vishnu. According to this legend, the region was created when Parasurama threw his axe into the sea Although it is known that the present-day region of Kerala was once governed by the Chera dynasty, little information exists regarding its early ethnography.
