Big cities like Poompuhar had the ‘Maruvurappakam’ (inland town) and ‘Pattinapakkam’ (coastal town), had market and bazaars where many merchants met one another for the purpose of selling or buying different kinds of commodities and food stuff. Port towns like Tondi, Korkai, Puhar and Muziri were always seen as busy with marts and markets with activities related to imports and exports. In such a brisk trade, people of the coastal region, engaged themselves in coastal trade and developed their intercontinental trade contacts.
