Mansabdari System was a system introduced by Akbar for military administration and territorial commands (grant and revenue) to sustain parts of army. His experiences led him to conclude that rather than relying in the Irani and Turkish nobles, he should also include the Indian Muslims (Sheikhzadas), Afghans and Rajputs in the Mughal army.
The Mughal officers whether Hindus or Muslims were granted territorial commands in return for the military service. They had to bring in some fixed number of men-at-arms, horses and elephants to the field and were rated as per the numbers which was known as Zats. So they were called Mansabdars of 10, 20, 100, and 1000 and so on.
