コロマンデル海岸
In 1637, Francis Day, a member of the Masulipatnam Council and Chief of the Armagon Factory, made a voyage of exploration down the Coromandel Coast as far as Pondicherry. At that time, the Coromandel Coast was ruled by the Raja of Chandragiri through a local chief or Nayak, Damarla Venkatapathy Nayak, who ruled the coast from Pulicat up to San Thome. He had his seat at Wandiwash and his brother, Ayyappa Nayak resided at Poonamallee.
