It is believed to have got it's name from a local word meaning "palace fort". During the Sangam Era, it was part of the Chera kingdom, who ruled it until 1122 A.D. After the Chera Empire fell apart, it came under the Polanadu area. The city came into existence during the 13th century, when Udaivar conquered it and built a fort at Velapuram. Udaiyavar called himself as Swami Nambiyathri Tirumalapad, and the title was later shortened to Samuri. Hyder Ali captured this area in 1776 and in 1792 it fell into British hands. The Kappad Beach located close to this city, was witness to a famous historical event. Name the city.
