The Nawab of Bengal was a hereditary ruler in Mughal India. This title encompassed the regions of Bengal, Bihar, and Orissa. Today, these areas form parts of modern Bangladesh and India. The Nawabs were powerful figures, especially during the 18th century, when they governed as de facto independent rulers.
Historical Context
The Bengal Subah was the wealthiest province in the Mughal Empire. It was crucial for the empire’s revenue. The Mughal administrative system included positions like Nizamat (governorship) and Diwani (premiership). The provincial premier, known as the Diwan, was responsible for revenue and legal affairs.
Rise of the Nawabs
As the Mughal Empire declined, the Nawabs gained power. Murshid Quli Khan, the first Nawab, emerged as the de facto ruler after a power struggle with the viceroy, Azim-us-Shan. In 1717, Mughal Emperor Farrukhsiyar recognised Khan as the hereditary Nawab Nazim. He shifted the capital from Dhaka to Murshidabad.
Economic Contributions
Bengal was production hub. It was known for cotton muslin, silk, shipbuilding, gunpowder, and saltpetre. Major cities like Dhaka, Patna, and Chittagong became centres of trade and industry. The Nawabs attracted traders from across Eurasia, enhancing Bengal’s economic landscape.
Military Engagements
The Nawabs faced numerous military challenges. Alivardi Khan, the Nawab from 1740 to 1756, engaged in conflicts with the Marathas. He also focused on rebuilding Bengal after these invasions. The last independent Nawab, Siraj-ud-Daulah, was wary of British expansion and launched the siege of Calcutta in 1756.
British East India Company Influence
The British East India Company began to rival the Nawabs’ authority. Following the siege of Calcutta, Robert Clive led a fleet to regain control. The subsequent Battle of Plassey in 1757 marked a turning point. The British defeated Siraj-ud-Daulah, leading to the establishment of Mir Jafar as a puppet Nawab.
Decline of Nawabi Power
The defeat of Mir Qasim in the Battle of Buxar in 1764 further diminished Nawabi power. The Nawabs lost their independent authority. The British established direct control over Bengal after 1772. By 1858, the British Crown took over, ending the Nawabs’ political influence.
Administrative Changes
In 1765, the East India Company received the Diwani of Bengal from Mughal Emperor Shah Alam II. This established a dual governance system. The Nawabs managed local affairs while the Company controlled revenue. By 1793, the Nawabs were reduced to a titular status.
Cultural Contributions
The Nawabs were patrons of arts and culture. They supported Mughal painting and Hindustani classical music. The Murshidabad style of painting flourished during their reign. Nawab Shuja-ud-Din Muhammad Khan developed the Farrabagh, a grand royal palace complex.
Relations with Zamindars
The Zamindars of Bihar had a complicated relationship with the Nawabs. Their loyalty was often tenuous. Rebellion and revenue withholding were common. Despite Bihar’s potential for revenue, the Nawabs struggled to collect taxes until later in their rule.
Legacy of the Nawabs
The Nawabs left a lasting legacy in Bengal. Their reign saw economic and cultural developments. The Hazarduari Palace, built in the 1830s, became a symbol of their authority. The last titular Nawab, Mansur Ali Khan, abdicated in 1880, marking the end of an era.

Decline of the Mughal Influence
As the Mughal Empire weakened, the Nawabs gained autonomy. They continued to pay nominal tribute to the Mughal court. However, their power was largely independent by the early 1700s. The decline of Mughal authority allowed the Nawabs to flourish.
British Colonisation
The British East India Company’s growing power altered the political landscape. The victory at Plassey allowed them to install puppet rulers. The Company gradually assumed control over Bengal’s administration and revenue. This paved the way for British colonisation of India.
Post-Nawab Era
After the abolition of the Nawab title in 1880, the descendants retained wealth but lost political power. They became part of the zamindar class, focusing on land ownership and local governance. The legacy of the Nawabs remains evident in Bengal’s culture and history.
