The title “Nawab of Bengal” refers to the hereditary rulers of Bengal, Bihar, and Orissa during the Mughal and post-Mughal period. The Nawabs played a crucial role in shaping Bengal’s political, economic, and cultural history until the region gradually fell under British control. However, confusion often arises when discussing the last Nawab of Bengal because the answer depends on context.

On one hand, Siraj-ud-Daulah (1733–1757) is widely recognized as the last independent Nawab of Bengal. He ruled without British interference until his defeat in the Battle of Plassey (1757). His loss began British dominance in Bengal and eventually across India.

On the other hand, Mansur Ali Khan (1830–1884) is regarded as the last titular Nawab of Bengal, since the title continued ceremonially under British authority even after real power had vanished. He abdicated in 1880, effectively ending the Nawabship.

Who Was the Nawab of Bengal?

The Nawab of Bengal was originally the Subahdar (provincial governor) of the Bengal Subah under the Mughal Empire. Bengal, one of the empire’s wealthiest and most productive provinces, was vital due to its fertile lands, flourishing trade, and thriving textile industry. Over time, the office of Subahdar became hereditary, and the title “Nawab of Bengal” came to represent semi-independent rulers who exercised administrative and military control over Bengal, Bihar, and Orissa.

The Nawabs of Bengal were political leaders and great cultural, trade, and architecture patrons. Their courts attracted scholars, poets, and artisans, making Bengal a hub of Indo-Persian culture. They played a decisive role in maintaining revenue collection, supporting commerce, and defending the province from external threats. However, their increasing independence from the Mughal center also made them targets for rising European trading powers.

The city of Murshidabad, founded by Nawab Murshid Quli Khan in the early 18th century, became the capital of Nawabi Bengal. It developed into a center of administration, commerce, and cultural patronage, symbolizing Bengal’s wealth and grandeur. Palaces like the Hazarduari and monuments such as Katra Masjid reflect this legacy.

Thus, the Nawab of Bengal embodied the political authority and cultural richness of one of India’s most prosperous regions until British intervention gradually eroded their sovereignty.

Siraj-ud-Daulah – The Last Independent Nawab

Early Life and Accession

Mirza Muhammad Siraj-ud-Daulah (1733–1757) was the grandson of Nawab Alivardi Khan, a capable ruler of Bengal. Raised in Murshidabad, he was trained in governance and warfare. Alivardi Khan appointed him his successor, though many nobles resented this choice. In April 1756, at just 23 years of age, Siraj ascended the throne of Bengal.

Challenges to His Rule

From the start, Siraj faced grave challenges. Bengal’s nobility was divided, and its commander-in-chief, Mir Jafar, secretly aspired to the throne. Court intrigues and jealousy undermined his authority. Meanwhile, the East India Company expanded its influence, fortifying its settlements without permission and refusing to pay trade duties. Siraj saw their actions as an attack on his sovereignty.

The Battle of Plassey (1757)

These tensions culminated in the Battle of Plassey on 23 June 1757. Although Siraj’s army was far larger than the British forces led by Robert Clive, betrayal determined the outcome. Mir Jafar, bankers like Jagat Seth, and generals like Rai Durlabh, sided with the British. Key sections of Siraj’s army withheld support, leading to a swift and decisive defeat.

Fall and Death

After the battle, Siraj fled towards Murshidabad but was soon captured. On 2 July 1757, he was executed on Mir Jafar’s orders, and the British installed their puppet on Bengal’s throne. This event marked the beginning of British political dominance in India.

Why He Is Called the Last Independent Nawab

Historians regard Siraj-ud-Daulah as the last independent Nawab of Bengal, since his fall ended absolute sovereignty. Later, Nawabs like Mir Jafar and Mir Qasim ruled only under British control and were stripped of autonomy.

Legacy

Though his reign was short, Siraj became a symbol of resistance against foreign domination. Nationalist narratives celebrate him as a martyr betrayed by insiders. His story reminds him of the dangers of disunity and the early spirit of India’s anti-colonial struggle.

Mansur Ali Khan – The Last Titular Nawab of Bengal

Early Life and Background

Mansur Ali Khan (1830–1884) was the last titular Nawab of Bengal, representing the final decline of Nawabi authority under British rule. Born in Murshidabad into the illustrious Nawabi lineage, he inherited a throne that no longer held absolute power. By the time he formally ascended in 1838, Bengal had long been under British control, and the Nawab’s role was largely ceremonial.

Reign and Challenges

Mansur Ali Khan’s reign (1838–1880) was dominated by subordination to the British. The East India Company, and later the British Crown, controlled Bengal’s administration, revenue, and military. Mansur Ali Khan could not command armies or implement independent policies, unlike his predecessors. Financial difficulties, disputes over revenues, and the erosion of traditional courtly influence marked his rule. Despite these limitations, he worked to maintain the dignity of his hereditary office while navigating the realities of colonial dominance.

Cultural and Social Influence

Although politically powerless, Mansur Ali Khan endeavored to preserve the cultural and social traditions of the Nawabi household. He supported education, administrative reforms, and artistic patronage in Murshidabad. His efforts ensured that the Nawabi court retained some grandeur and that Bengali traditions continued to flourish despite the decline of political authority.

Abdication and End of Nawabi Rule

By 1880, Mansur Ali Khan abdicated, facing overwhelming British interference and financial pressures, formally ending his reign. He died in 1884 in Murshidabad, marking the symbolic end of the Nawabship of Bengal. His son, Hassan Ali Mirza, inherited the title of Nawab of Murshidabad, but this position was purely ceremonial.

Why He Is Called the Last Nawab of Bengal

Mansur Ali Khan is regarded as the last titular Nawab of Bengal because his abdication erased the remaining semblance of Nawabi sovereignty. After Siraj-ud-Daulah’s fall in 1757, the Nawabs had already been reduced to British puppets, but Mansur Ali Khan’s exit marked the final dissolution of independent authority.

Legacy

Mansur Ali Khan symbolizes the end of an era. While his reign lacked political power, his dedication to cultural preservation and governance in Murshidabad ensured that the Nawabi legacy endured, leaving behind a ceremonial yet historically significant imprint in Bengal’s history.

Conflict with the East India Company

Economic interests and political tensions shaped the relationship between the East India Company and the Nawabs of Bengal, ultimately paving the way for British colonial dominance in India. The Company, established in 1600, initially focused on trade but gradually expanded its influence in Bengal. Under Nawab Murshid Quli Khan, the Company enjoyed significant trading privileges. However, successive Nawabs, including Alivardi Khan, grew wary of its power and sought to limit British influence.

Economic grievances were central to the conflict. The Company’s control over trade monopolies clashed with the Nawabs’ efforts to protect Bengal’s revenue and commercial autonomy. Under Mir Jafar, the Company further consolidated its trade dominance, often provoking rivalries with European powers like the Dutch and the French.

The Battle of Chandernagar (1757) illustrates this complex colonial rivalry. Chandernagar, a French settlement, became a focal point during the competition between the British and French East India Companies. Siraj-ud-Daulah allied with the French to resist British expansion, but the British victory at Chandernagar weakened French influence and strengthened their position in Bengal.

The fallout from Chandernagar set the stage for the Battle of Plassey later that year, undermining the Nawab’s authority and accelerating the decline of independent rule in Bengal. The economic and political pressures exerted by the East India Company exemplify how trade ambitions and colonial strategy combined to dismantle local sovereignty, leaving the Nawabs powerless under British control.

Thе diplomatic efforts borе fruit, lеading to thе formation of a powerful anti-Siraj coalition.
