It was important for the Mughals to recruit mansabdars from diverse backgrounds and not just Turanis and Iranis because:

1. The empire had expanded to encompass different regions and provinces thus it was needed to provide stability to the empire.

2. The problems of common folks would be understood better by the people living with them only.

3. Mughal also didn’t wanted people to rebel against them on the issue of privileges to Turanis and Iranis.

4. They came here to rule so they needed to maintain a balance between the diversity of the country as well as respect it.
