In-Depth History of Rajmahal

1. Early History and Strategic Positioning

• Gaur as previous capital (1202–1576) declined due to:
  • Shifting course of the Ganga River (moved westward)
  • Plague of 1575 that decimated the population
  • Increasingly unsanitary and uninhabitable conditions
• Rajmahal chosen as the new capital by Man Singh, Akbar’s representative
• Fortifications and palace constructed to emphasize governance and defense

2. Establishment as Akbar Nagar

• Capital officially established in 1592
• Originally called Agamahal, later renamed Rajmahal, and then Akbar Nagar
• Strategic location on the Ganga provided:
  • Natural protection
  • Access to inland trade routes
• Man Singh ensured:
  • Strong defensive walls and towers
  • Efficient city planning for administration

3. Shift from Rajmahal to Dhaka

• Capital shifted to Dhaka in 1612 due to:
  • Dhaka’s superior strategic position against threats from Arakanese and Portuguese pirates
  • Dhaka’s better maritime trade access
  • Continued shifting of the Ganga, reducing Rajmahal’s commercial utility
• French traveler Tavernier (1666) noted Rajmahal’s decline due to these factors

4. Military Engagements and Political Struggles

• Site of major Mughal military engagements, especially:
  • Shah Jahan’s rebellion (1622) against Emperor Jahangir

• Became a military outpost during the Mughal succession wars

5. Shah Jahan’s Contributions to Rajmahal

• Became an administrative center for his son Shuja, governor of Bengal

6. Rajmahal During the Succession Struggles

• Prince Shuja governed Bengal from Rajmahal during succession conflicts
• Invested in the construction of grand palaces and administrative structures
• Defeated by Aurangzeb during the struggle for the Mughal throne (1658)
• Mīr Jumla captured Rajmahal, marking a turning point in its decline

7. Decline of Rajmahal

• Decline accelerated under Aurangzeb’s centralized rule
• River course shift and rise of Dhaka as a capital led to abandonment
• Fortifications dismantled, city infrastructure deteriorated
