Ko Kizhan Adikal
Ko Kizhan Adikal Ravi Neeli was the traditional title of the queens/princesses of the Chera Perumal kingdom in medieval south India. It was initially assumed that Kizhan Adikal was a proper given name (and not a royal title).
The title was used by Kerala princesses (in the Tamil country) even after their marriages to Chola princes.
