The Mughal empire was very difficult to administer. This is because decisions and messaged had to be relayed across thousands of miles and it would emperors did not know what was happening throughout the empire because of its vastness. When rebellions broke out, it would be months before they could take action to end them. This is one of the reasons why Aurangzeb encouraged the use of Mansabdars. This is a huge reason for the decline of the empire.
