The book 'Bengal in Maps (1949)' is an authentic document of the geographical and political evolution of Bengal following the 1947 partition. How Bengal was divided into two parts after the partition of 1947—West Bengal of India and the then East Bengal of Pakistan—the picture of that historical change has been very accurately presented in this book in the context of 1949. The complexities of border determination due to the influence of the Radcliffe Line, the inclusion of the Sylhet district of Assam, and the position of enclaves scattered within the maps have been analyzed in detail in the book. Not only the boundaries, but also the transformation of Kolkata and Dhaka as administrative centers and the change in the geographical positions of the princely states (such as Cooch Behar and Tripura) have gained importance here. For history enthusiasts, researchers, or map collectors, it is an essential book that will help in understanding the early history of the formation of the borders of present-day Bangladesh and West Bengal.
