Reasons for allowing earlier rulers to continue in their old kingdoms:

During the Mughal Empire, the emperors had a policy of allowing the earlier rulers to continue in their old kingdoms. This practice was motivated by several reasons, including political stability, administrative efficiency, religious tolerance, and diplomatic considerations.

Political Stability:
One of the main reasons for allowing the earlier rulers to continue in their old kingdoms was to maintain political stability. The Mughals realized that abruptly removing the existing rulers and replacing them with their own appointees could lead to unrest and rebellion. By retaining the local rulers, the Mughals ensured a smoother transition of power and maintained the loyalty of the local population.

Administrative Efficiency:
Another important factor was administrative efficiency. The Mughals recognized that the local rulers had extensive knowledge of their respective regions, including the local customs, traditions, and administrative systems. Allowing the existing rulers to continue in their positions ensured the efficient functioning of the administration and prevented any disruption in governance.

Religious Tolerance:
The Mughals were known for their policy of religious tolerance. By allowing the earlier rulers to continue in their old kingdoms, the Mughals demonstrated their commitment to religious harmony. This approach helped prevent religious tensions and allowed the different communities to coexist peacefully under Mughal rule.

Diplomatic Considerations:
Allowing the earlier rulers to retain their power also had diplomatic advantages. The Mughals maintained a vast empire that encompassed diverse regions and cultures. By respecting the authority of local rulers, the Mughals gained their support and cooperation. This approach helped in building alliances and maintaining stability within the empire.

Conclusion:
In conclusion, the Mughals allowed the earlier rulers to continue in their old kingdoms to ensure political stability, administrative efficiency, religious tolerance, and diplomatic considerations. This policy helped in maintaining the unity and harmony of the empire, while also benefiting from the expertise and cooperation of the local rulers.
