While consultation of contemporary sources is called for to reflect upon these key issues, it tends to be under- used by modern historians. Furthermore, the unavailability of inscriptional evidence for the river forts has led the relevant researchers to an unremitting debate concerning the river forts and the identity of their builders. These limitations suggest the need for further study. This study suggests that an advanced study, analysing and discussing contemporary and modern sources, along with field work conducted on the sites of the river forts, can clarify and resolve the various outstanding problems, thereby present and defend an improved understanding about the building and purpose of the river forts. This study suitably focuses on the historical changes in the course of the river systems and their impact on the building of river forts. Moreover, it examines in close details the role of river forts in the defence of Dhaka against various enemies, such as internal (bhuiyans, zaminders and their Afghan allies) and external (sea-borne invaders, such as the Maghs of Arakanese and the Portuguese) during the period 1575-1688. Finally it reasons out that a satisfactory study on the Mughal history in Bangladesh largely depends on pursuing a comprehensive and advanced study of the physical evidence and on wider consultation of contemporary and modern textual sources such as Persian, Bengali, Assamese and Arakanese. 3 | P a g e ACKNOWLEDGEMENT I am deeply indebted to my two supervisors, Professor Denys Pringle and Professor Geoffrey Samuel, for their unfailing supervision, constructive criticism and invaluable advice at all time throughout the period of my study. Without their patience and inspiration, this thesis would not have had accomplished a complete form. I am truly fortunate to have them as my supervisors. I would like to express my gratitude and appreciation for my brother-in-law, Mohammad Raju Ahmed for his unconditional assistance. Without his aid, maps and figures provided in this thesis would not have been possible to be furnished. Thanks are also due to the Archaeology Department of Bangladesh for granting me permission to visit their archive and compile rare photographs. I offer my appreciation to the staff of Cardiff Archaeology section, Sarah Tovey and Helen Szewczyk, for their assistance. I am also indebted to the library, particularly the inter–library loan staff at Cardiff University for their assistance throughout the study period. Finally, I owe a debt of gratitude to my parents, son and husband for their forebearance and understanding in coping with the difficulties inherent in such an undertaking. 4 | P a g e TABLE OF CONTENTS Page LIST OF MAPS 7 LIST OF FIGURES 8 LIST OF PLATES 9 PART ONE The Current State of Knowledge, and Outstanding Problems 11 Chapter 1 : Introduction 12 Chapter 1.1 : Brief Introduction: the Main Questions 12 Chapter 1.2 : Source and Scope of Study 16 Chapter 2 : Historical Background 23 Chapter 2.1 : Political History 23 Chapter 2.2 : Economic History 33 Chapter 3 : River Systems and Historical Changes in the Systems 44 Chapter 3.1: Major River System 44 Chapter 3.2: Historical Changes in the Systems 47 Chapter 4 : Descriptions and Discussion of the River Forts: Architectural Relationship of the River Forts with 54 Other Buildings of the Period Chapter 4.1 : Descriptions and Discussion of the Hajiganj, the Sonakanda and the Idrakpur River Forts 54 4.1.1 : The Hajiganj River Fort 54 4.1.2 : The Sonakanda River Fort 60 4.1.3 : The Idrakpur Rivet Forts 65 Chapter 4.1.4 : The Relationship Between the Architecture of the River Forts and that of Other Architecture of the 71 Period 5 | P a g e Chapter 5 : Military Strategy and Techniques in the Period 77 PART TWO Analytical Discussion 102 Chapter 6 : Resistance to the Mughal Rulers, 1576-1611 : The Role of Isa Khan and Other Bhuiyan Leaders 104 Chapter 7 : Islam Khan, Mughal Subahdar, 1608-1613, and His Immediate Successors: The Portuguese and Arakanese/Magh Threats during This Period 121 Chapter 8 : Shah Shuja, Mughal Subahdar, 1639-1660 : The Portuguese and Arakanese/Magh Threats during This Period 140 Chapter 9 : Mir Jumla, Mughal Subahdar, 1660-63 : The Portuguese and Arakanese/Magh Threats during This Period 148 Chapter 10 : Shaista Khan, Mughal Subahdar, 1663-1678, 1680- 156 88: Campaign against Chittagong PART THREE Chapter 11 : Conclusion 164 BIBLIOGRAPHY 177 MAPS 1-16 185-202 FIGURES 1-12 203-213 PLATES 1- 20 214- 234 6 | P a g e LIST OF MAPS Pages 185-202 Maps Page 1.
