I known that jagir was the father of shah jahan who built taj mahal

Mansabdars were the patrons who joined the Mughal service. The term mansabdar refers to an individual who holds a mansab, which means a position or rank. It was a grading system used by the Mughals to fix the rank, salary and military responsibilities. Each mansabdar had to maintain a specified number of sawar or cavalrymen. A jagir was a revenue assignment for the mansabdars. The mansabdars had the right to collect revenue from a jagir but they could not reside in or administer the jagir. They only had rights to the revenue of their assignments which was collected for them by their servants while the mansabdars served in some other part of the country. In Akbar’s reign, these jagirs were carefully assessed so that their revenues were roughly equal to the salary of the mansabdar.
