The Mansabdari system was the most important feature of the Mughal administration. The Mansab means rank. Each noble was given a mansab or rank and was called the mansabdar. The mansab or rank was based on the numbers of mounted soldiers at the command of the officers. Each mansabdar was required to perform any civil and military duty as was assigned to him by the emperor. Mansab was not hereditary. Hence it could not be passed on to his descendants. Thus every mansabdar owed his allegiance to the emperor.
Classes of Mansabdars. In the period of Akbar, Mansabdars had 33 classes. The lowest mansabdar had 10 soldiers and the highest mansabdar had 10,000 soldiers in his subordination.
Duties of Mansabdars. Mansabdars were appointed by the emperor at the recommendation of Mir Bakhshi. He could be put to any work. The salary was also given according to his class. He could be promoted as well as denoted in status as well as salary.
