The book focuses on the changes in the Trading world of the Tamil Merchants in the southern Coromandel region, with the arrival of European trading companies and the concomitant creation of European port enclaves and the rapid expansion of demand for Coromandel cotton textiles. The author uses impressive range of original sources — literary, inscriptional and archival — to cover a long period of history (beginning with the maritime trade in the Sangam period) to argue that the merchants evolved over the centuries into a distinct class of merchant capitalists with a conscious perception of their identity as an economic and social class.
