In this article an attempt has been made to identify misinterpretation of some leading modern works on social history of Sultanate Bengal (1204- 1574 A.D), which will, hopefully, help us - the new research scholar in history - portray more accurately the socio-economic developments of the period in question. For this purpose, a number of pioneering as well as authentic works in the field have briefly been reviewed and some of their important shortcomings related to our treatment have been pointed out. It shows that none of these leading works contains any information appropriate to the study of a unified social history of Bengal and all of them utterly fail to present a picture of changing socio-economic circumstances that took place simply due to the advent of a new ruling elite of foreign origin in the thirteenth century.
