Under whom did Bengal gradually break away from the Mughal control in the 18th century? Correct Answer Murshid Quli Khan

By the end of the 17th century, the Mughal Empire started facing multiple crises. Emperor Aurangazeb, who was the last powerful Mughal Emperor, had exhausted the military and the financial resources of his empire by fighting a long war in Deccan.

• The efficiency of the imperial administration broke down and Mughal Emperors were not able to keep a check on the powerful mansabdars. (mansabdar referred to an individual holding a mansab, meaning a position or rank.)
• Three Mughal provinces that stand out prominently are Awadh, Hyderabad, and Bengal.
• The Mansabdars of these provinces took advantage of the late 17th-century crisis.

Additional Information

• Nadir Shah was the ruler of Iran. In 1739, he sacked and plundered Delhi and carried away a huge amount of wealth. 
• Alivardi Khan was the Nawab of Bengal from 1740-1756. He came to the throne after Murshid Quli Khan. 
• Burhan-ul-Mulk was the Subadar of Awadh. He manages the political, financial, and military affairs of the province of Awadh. 

Hence, it becomes clear that in the 18th century, Bengal gradually broke away from the Mughal control under Murshid Quli Khan.
