The Indian coastline is vast and stretches over 6,100 kms. The eastern coastline is called the Coromandel Coast, whereas the western coastline is referred to as Konkan and Malabar coast. The numerous ports on this coastline had attracted the Romans from time immemorial. Foreign trade was carried on in those days only through sea-routes. Thus these ports developed and became the cause for the rise of powerful kingdoms in the South like the Pandyas, the Cheras and the Cholas.
