Shah Alam II granted the diwani rights of Bengal, Bihar, and Orissa to the East India Company in 1765.
In 1765, the Mughal Emperor Shah Alam II transferred the diwani rights of Bengal, Bihar, and Orissa to the East India Company. That move marked a dramatic shift in India’s colonial history.
What was the geographic context of this diwani transfer?
The fertile plains of eastern India—Bengal, Bihar, and Orissa, drained by the Ganges and Brahmaputra river systems, were the regions affected.
This diwani gave the East India Company authority over some of the most economically productive lands in the Mughal Empire. Picture vast agricultural output—rice, silk, indigo—that made these regions critical to imperial revenue. The transfer happened under the Treaty of Allahabad, signed on August 12, 1765, between Shah Alam II and Robert Clive, the British governor of Bengal. That treaty didn’t just hand over fiscal control—it set the stage for the Company’s political dominance across India.

What made the diwani such an important revenue collection right?
The diwani traditionally allowed Mughal emperors to tax agricultural lands and administer civil justice, a power now transferred to the East India Company.
Before 1765, local nawabs under Mughal authority handled these functions. Then came the Battle of Buxar in 1764, where the East India Company crushed the combined forces of the Nawab of Bengal, the Nawab of Awadh, and even the Mughal Emperor himself. That victory proved the Company’s military superiority beyond doubt. The Treaty of Allahabad that followed didn’t just hand over revenue rights—it wrapped the Company in the symbolic authority of the Mughal throne. Shah Alam II, though still called emperor, was barely in control beyond Delhi. By accepting British protection and ceding the diwani, he entered a shaky alliance that would slowly strip away Mughal sovereignty.
How did the diwani transfer impact the East India Company’s finances?
The Company began extracting vast wealth from Bengal’s economy, funding its expansion across India.
The economic ripple effects were immediate. Bengal’s rice fields, silk workshops, and indigo plantations became cash cows for the Company. Historians like Britannica point out that this financial windfall let the Company bankroll armies, administer territories, and project power far beyond Bengal. Honestly, this is the financial backbone that let the British tighten their grip on India. That revenue stream bankrolled the conquest of Mysore and the Maratha Empire—no small feat.
Where can I visit to see sites connected to the 1765 diwani transfer?
Plassey (Palashi), Allahabad (Prayagraj), and Murshidabad are key historical sites tied to these events.
These events unfolded in northern India, but their legacy lives on in several places you can visit today:
- Plassey (Palashi), West Bengal (23.80°N, 88.25°E): The site of the 1757 Battle of Plassey, where the Company first defeated the Nawab of Bengal. A memorial marks this turning point in colonial history.
- Allahabad (Prayagraj), Uttar Pradesh (25.4358°N, 81.8463°E): The city where the Treaty of Allahabad was signed. The Allahabad Fort, a UNESCO World Heritage Site, stands as a symbol of Mughal-British interaction.
- Murshidabad, West Bengal (24.18°N, 88.27°E): The former capital of Bengal under Nawab Siraj-ud-Daulah, whose defeat at Plassey paved the way for British control.
If you’re into colonial history, these spots offer a window into how the diwani reshaped India’s political and economic landscape. Access is generally unrestricted, and guided tours in Murshidabad and Allahabad often dig deeper into the Mughal-British transition. The National Park Service suggests visiting during the cooler months (October–March) for comfortable exploration.
As of 2026, these regions remain culturally rich, blending Mughal architecture with colonial-era landmarks. The legacy of the diwani still echoes in Bengal’s administrative and economic structures—a reminder of a transformative moment in South Asian history.
