Under Murshid Quli Khan, Bengal gradually broke away from Mughal control. He was appointed as the naib, deputy to the governor of the province. Although never a formal subadar, Murshid Quli Khan very quickly seized all the power that went with that office. Soon, he began to command the revenue administration of the state. In order to reduce Mughal influence in Bengal he transferred all Mughal jagirdars to Orissa and ordered a major re-assessment of the revenues of Bengal. Revenue was collected in cash with great strictness from all zamindars.
