The Mughals retained many features of the administrative system of the Sultanate and Shershah.
Under Shershah the administrative units of Pargana (a group of villages), sarkar (a group of parganas) and groups of sarkars (some what like subas or province) were placed under specific offices.
The Mughals formalized a new territorial unit called suba.
Institutions of Jagir and Mansab system were also introduced by the Mughals.
Thus change and continuity both marked the Mughal administrative structure which brought about a high degree of centralisation in the system.
