In contrast to their predecessors, the Mughals created an empire and accomplished what had hitherto seemed possible for only short periods of time.

They imposed structures of administration and ideas of governance that outlasted their rule, leaving a political legacy that succeeding rulers of the subcontinent could not ignore.
