Battle of Buxar (1764): Causes, Events & Consequences
Complete UPSC guide to the Battle of Buxar — combined forces of Mir Qasim, Shuja-ud-Daulah, and Shah Alam II vs the East India Company, Treaty of Allahabad, and the Diwani grant.
The Battle of Buxar, fought on October 22, 1764, was the decisive military engagement that established British supremacy in India. Unlike the Battle of Plassey (1757) — which was decided by conspiracy rather than combat — Buxar was a genuine pitched battle in which the East India Company‘s forces under Major Hector Munro defeated the combined armies of three Indian powers: Mir Qasim (deposed Nawab of Bengal), Shuja-ud-Daulah (Nawab of Awadh), and Shah Alam II (the Mughal Emperor).
The Treaty of Allahabad (1765) that followed Buxar gave the Company Diwani rights (revenue collection authority) over Bengal, Bihar, and Orissa — transforming it from a trading company into a territorial power. For UPSC, Buxar is often considered more significant than Plassey.
Background: Mir Qasim's Rebellion
After Plassey (1757), the Company installed puppet nawabs in Bengal. When Mir Jafar proved difficult to manage, the Company replaced him with his son-in-law Mir Qasim in 1760.
Mir Qasim was initially cooperative — he gave the Company the districts of Burdwan, Midnapur, and Chittagong as payment. But he was also a capable and ambitious ruler who tried to reform Bengal's administration and build an independent military.
Conflict Over Private Trade
The fundamental conflict was the same issue that had triggered the Plassey crisis: misuse of trade privileges (dastaks).
Company employees used duty-free trade passes intended for the Company's official business to conduct their private trade — undercutting Indian merchants who had to pay duties. Mir Qasim protested. When the Company refused to stop the abuse, Mir Qasim took a radical step: he abolished all internal duties for everyone — Indian and European alike.
This equalised the playing field — which the Company found intolerable. A Company that could not enjoy trade privileges had no competitive advantage. Negotiations failed, and war broke out in 1763.
Mir Qasim's Defeat and Flight
The Company defeated Mir Qasim's forces in a series of battles in Bengal (1763). Mir Qasim fled westward, seeking allies. He found them:
- Shuja-ud-Daulah, the Nawab of Awadh — who controlled one of the wealthiest and most populous Mughal provinces
- Shah Alam II, the Mughal Emperor — who was at that time a wanderer, dependent on Awadh's protection, but whose name still carried legal and symbolic authority
Together, they assembled a coalition army to drive the Company out of Bengal.
The Battle: October 22, 1764
Forces
| Side | Commander | Estimated Troops |
|---|---|---|
| Company | Major Hector Munro | ~7,000 (including Indian sepoys and a small European contingent) |
| Combined Indian forces | Mir Qasim, Shuja-ud-Daulah, Shah Alam II | ~40,000 (some estimates higher) |
The Engagement
The battle was fought at Buxar (present-day Buxar district, Bihar) on the banks of the Ganga.
Unlike Plassey, this was a hard-fought battle:
- The Indian combined army had a significant numerical advantage
- However, the three allies were poorly coordinated — each commander maintained separate forces with different objectives and loyalties
- Munro imposed strict discipline on his forces (he had dealt with a sepoy mutiny just before the battle and executed ringleaders)
- The Company's disciplined infantry and effective use of artillery proved decisive
After several hours of fighting, the Indian coalition's forces broke and fled. Shuja-ud-Daulah retreated toward Awadh. Shah Alam II switched sides and approached the British. Mir Qasim fled and eventually died in obscurity (~1777).
Casualties: The Company lost approximately 847 men (killed and wounded). Indian losses were significantly higher — estimated at several thousand.
The Treaty of Allahabad (1765)
After Buxar, Robert Clive (who returned to Bengal as Governor in 1765) negotiated the Treaty of Allahabad with the defeated powers. The treaty had two parts:
Treaty with Shah Alam II (Mughal Emperor)
| Provision | Significance |
|---|---|
| Shah Alam II granted the Company Diwani (revenue collection rights) of Bengal, Bihar, and Orissa | Legal legitimacy — the Company now collected revenue by imperial grant, not mere conquest |
| The Company would pay the Emperor an annual tribute of Rs. 26 lakh | Token payment — far less than Bengal's revenue |
| Shah Alam received the districts of Kora and Allahabad | A small territorial consolation |
Treaty with Shuja-ud-Daulah (Nawab of Awadh)
| Provision | Significance |
|---|---|
| Awadh was restored to Shuja-ud-Daulah | The Company chose not to annex Awadh — keeping it as a buffer state |
| Shuja-ud-Daulah paid Rs. 50 lakh as war indemnity | Drained Awadh's treasury |
| Allahabad and Kora given to Shah Alam II | Carved out of Awadh's territory |
| Awadh became a Company protectorate | Shuja-ud-Daulah accepted a subsidiary force arrangement |
Significance: Why Buxar Matters More Than Plassey
| Aspect | Plassey (1757) | Buxar (1764) |
|---|---|---|
| Nature | Conspiracy — Mir Jafar's army didn't fight | Genuine military victory against a coalition |
| Opponents | One nawab (Siraj-ud-Daulah) | Three powers — Nawab of Bengal, Nawab of Awadh, Mughal Emperor |
| Military significance | Minimal — decided by treachery | High — demonstrated Company's battlefield superiority |
| Political result | Company became kingmaker in Bengal | Company gained legal sovereignty (Diwani) over Bengal-Bihar-Orissa |
| Imperial legitimacy | None — Company had no Mughal sanction | Full — Mughal Emperor himself granted Diwani |
| Territory | Informal control over Bengal | Formal control over Bengal + Awadh as buffer |
The Diwani was the critical outcome. The Company now had the legal right — granted by the Mughal Emperor — to collect revenue from Bengal, Bihar, and Orissa. This gave the Company approximately £2–3 million annually in revenue — an enormous sum that financed all subsequent conquests.
Dual Government (1765–1772)
After obtaining the Diwani, Clive established a system called the Dual Government (or "Dual Administration"):
- Revenue collection (Diwani): In the Company's hands (through Indian agents — the naib dewan was an Indian official)
- Administration and criminal justice (Nizamat): Nominally in the Nawab's hands
In practice, the Company collected the revenue while the Nawab handled administration. Neither was accountable — the Company blamed the Nawab for administrative failures, and the Nawab blamed the Company for revenue extraction.
This system was a disaster for Bengal. Revenue was maximised, expenditure on welfare was minimised, and the Bengal Famine of 1770 — which killed an estimated one-third of Bengal's population (roughly 10 million people) — occurred partly because the Company continued to extract high revenue even during the famine.
The Dual Government was ended by Warren Hastings in 1772 when he became Governor of Bengal and assumed direct administrative control.
