The Nawab of Bengal[1][2][3][4] (Bengali: বাংলার নবাব) was the hereditary ruler of Bengal Subah in Mughal India. The Nawab of a princely state or autonomous province is comparable to the European title of Grand Duke. In the early 18th-century, the Nawab of Bengal was the de facto independent ruler of the three regions of Bengal, Bihar, and Orissa which constitute the modern-day Indian states of West Bengal, Bihar and Orissa; and the sovereign state of Bangladesh.[5][6][7] They are often referred to as the Nawab of Bengal, Bihar and Orissa (Bengali: বাংলা বিহার ও ওড়িশার নবাব).[8] The Nawabs were based in Murshidabad which was centrally located within Bengal, Bihar, and Orissa. Their chief deputy was the Naib Nazim of Dhaka.

Bengal Subah was one of the largest, wealthiest and most influential provinces in the Mughal Empire. In 1717, the Mughal Emperor Farrukhsiyar replaced the imperial viceroy of Bengal with the position of a hereditary Nawab. Murshid Quli Khan, a former prime minister, became the first Nawab. The Nawabs continued to issue coins in the name of the Mughal Emperor. But for all practical purposes, the Nawabs governed as independent monarchs. Bengal continued to contribute the largest share of funds to the imperial treasury in Delhi. The Nawabs, backed by bankers such as the Jagat Seth, became the financial backbone of the Mughal court. During the 18th-century, the Nawabs of Bengal were among the wealthiest rulers in the world.[9]
The Nawabs of Bengal oversaw a period of proto-industrialization. The Bengal-Bihar-Orissa triangle was a major production center for cotton muslin cloth, silk cloth, shipbuilding, gunpowder, saltpetre, and metalworks. Factories were set up in Murshidabad, Dhaka, Patna, Sonargaon, Chittagong, Rajshahi, Cossimbazar, Balasore, Pipeli, and Hugli among other cities, towns, and ports. The region became a base for the British East India Company, the French East India Company, the Danish East India Company, the Austrian East India Company, the Ostend Company, and the Dutch East India Company.
The British company eventually rivaled the authority of the Nawabs. In the aftermath of the Siege of Calcutta in 1756, in which the Nawab's forces overran the main British base, the East India Company dispatched a fleet led by Robert Clive who defeated the last independent Nawab Siraj-ud-Daulah at the Battle of Plassey in 1757. Mir Jafar was installed as the puppet Nawab. His successor Mir Qasim attempted in vain to dislodge the British. The defeat of Nawab Mir Qasim of Bengal, Nawab Shuja-ud-Daula of Oudh, and Mughal Emperor Shah Alam II at the Battle of Buxar in 1764 paved the way for British expansion across India. The South Indian Kingdom of Mysore led by Tipu Sultan overtook the Nawab of Bengal as the subcontinent's wealthiest monarchy; but this was short-lived and ended with the Anglo-Mysore War. The British then turned their sights on defeating the Marathas and Sikhs.
In 1772, Governor-General Warren Hastings shifted administrative and judicial offices from Murshidabad to Calcutta, the capital of the newly formed Bengal Presidency; and the de facto capital of British India.[10] The Nawabs had lost all independent authority since 1757. In 1858, the British government abolished the symbolic authority of the Mughal court. After 1880, the descendants of the Nawabs of Bengal were recognized with a new title called Nawab of Murshidabad (Bengali: মুর্শিদাবাদের নবাব) with the status of a peerage.[11]
