Mannarghat Muppil Nair ('Kunnattattil Madambil Nair) was the royal title usually given to the eldest male member of Mannarghat Muppil Nair family. He was a "desavazhi" (provincial governor) under Valluvanad (southern Malabar, India), looking after the eastern boundary and the hilly areas. The Nairs had considerable land holdings in the area and also held about 70% of the land in Attappadi, including Silent Valley.
