Descriptions about the rulers of Eranad and Valluvanad regions can be seen in the Jewish copper plates of Bhaskara Ravi Varman (around 1000 CE) and Viraraghava copper plates of Veera Raghava Chakravarthy (around 1225 CE).[32] Eranad was ruled by a Samanthan Nair clan known as Eradis, similar to the Vellodis of neighbouring Valluvanad and Nedungadis of Nedunganad. The rulers of Valluvanad were known by the title Eralppad/Eradi.
