ABSTRACT
This chapter presents a period covering more than three and a half centuries in the history of medieval Bengal, which began with the establishment of the Turkish rule under the leadership of Ikhtiyar al-din Bakhtiyar Khalji. It is important that most of the find spots of the coin hoards and mint towns are in and around a river course, either on the bank of the principal river or near its tributaries which had direct link with the main river. The influence of the Vanga complex of mints grew with the fourteenth century expansion of the sultanate to the delta region. Sunargaon is situated on a strategically important point for trading on the Meghna river near the confluence of the Padma, Meghna and some other tributaries. Chittagong was the most important port town and was well-connected with Sunargaon through the Meghna and its estuary.
