Starting from the British colonial rule (1757-1947) through 1947 partition, creation and subsequent break-up of Pakistan down to the emergence of Bangladesh as a nation state in 1971, the present book is about the state formation in South Asia involving the three countries, India, Pakistan and Bangladesh with a special focus on the creation of the Bangladesh state from a historical perspective. Very often than not scholars and academicians raised the questions: Was the 1947 Indian's partition (un)avoidable? Similar question is raised in case of Pakistan: Was the break-up of Pakistan and the creation of Bangladesh inevitable? The state of Pakistan that came into being in 1947 was not in commensurate with the state vision of the progressive section of the Bengal Provincial Muslim League including Bangabandhu Sheikh Mujibur Rahman, later on creator of Bangladesh. Then, what was their vision of state? The book seeks answers to these questions. Along with these, the book may be seen as a treatise on why and how Bangladesh. This is a kind of follow-up to the author's earlier widely read and referred book, The Foreshadowing of Bangladesh being published by UPL. Beyond a long introduction and a modestly drawn conclusion, the book includes 11 chapters under three parts and 7 appendices, which are also very pertinent to the subject matter. It is hoped that the readers will find the book very useful for their further understanding of the gamut of state formations in South Asia especially the creation of the State of Bangladesh in 1971 under the leadership of Bangabandhu Sheikh Mujibur Rahman.
