How Bengal Fell: The British Takeover and the Turning Point of Colonial India

Modern History

The succession from Mughal permissions to outright colonial subjugation in Bengal is one of the most dramatic shifts in Indian history. From privileges granted in court to treaties inked in Allahabad—and finally to exploitation of administrative power—this journey marks the British transformation from traders to rulers.

1. From Farmans to Dastaks: Trade Privileges That Turned Toxic

In 1717, Mughal Emperor Farrukhsiyar granted the English East India Company a royal farman authorizing duty‑free export and import from Bengal. The grant also allowed issuing dastaks (trade permits exempting custom duties) for company goods. However, Company officials abused these privileges—even using dastaks illegally on non-company goods—resulting in steep losses to the Mughal treasury and escalating tensions with local traders and authorities.

2. Siraj‑ud‑Daulah Rises: Confronting Corporate Arrogance

In 1756, Siraj‑ud‑Daulah became the Nawab of Bengal. Alarmed by the Company’s growing power and its violation of Mughal norms, he revoked trade privileges and demanded observance of earlier regulations established under Nawab Murshid Quli Khan. When the Company refused, tension escalated rapidly. The British fortified their Calcutta factories without authorization—provoking the Nawab.

3. The Black Hole of Calcutta: Tragedy & Retaliation

Siraj ordered the capture of Fort William on June 20, 1756. Approximately 146 English prisoners were confined in a small 14×18‑ft cell overnight, where 123 succumbed to suffocation in what became known as the Black Hole of Calcutta. This tragedy enraged the British public and leadership in Madras.

4. Battle of Plassey (1757): When Strategy Trumped Numbers

Robert Clive led an expedition to Bengal with covert reinforcement from Madras. Meanwhile, he cultivated Siraj’s disgruntled nobles—Mir Jafar, Rai Durlabh, Jagat Seth, and others. On June 23, Clive’s smaller force engaged the Nawab’s superior numbers. Torrential rain drenched the Nawab’s artillery, and betrayal from Mir Jafar and allies allowed Clive’s East India Company to seize victory—without a pitched battle.

Siraj‑ud‑Daulah fled but was captured and executed by Miran (Mir Jafar’s son), eliminating real resistance.

5. Mir Jafar’s Puppet Regime

Installed as Nawab, Mir Jafar signed a treaty granting the Company far-reaching trade rights. However, he quickly proved unreliable—failing to meet British financial expectations and answerable to suspicions of collaborating with the Dutch. The British deposed him once more and brought his son-in‑law, Mir Qasim, to rule.

6. Mir Qasim’s Reforms and the Counterstrike

Mir Qasim attempted to assert independence by equalizing customs duties for Indian and British traders. He abolished company privileges, reorganized his army, and even shifted his capital to Monghyr to escape British proximity.

The British objected, declaring war. In 1763, they engaged Qasim’s forces, compelling him to flee to Patna. When the Company’s local factory chief sought to seize Patna, Qasim allied with Shah Alam II and Nawab Shuja‑ud‑Daulah, forming a coalition that confronted the Company at the Battle of Buxar.

7. Battle of Buxar (1764) – The Decisive Blow

On October 22, 1764, the allied army of Qasim, Shah Alam II, and Shuja‑ud‑Daulah met the East India Company at Buxar. The conflict was decisive: the British emerged victorious — consolidating their supremacy over Bengal, Bihar, and Orissa.

8. Treaty of Allahabad & the Birth of Diwani Rights

In 1765 at Allahabad, Robert Clive secured two pivotal treaties. Under them, Shah Alam II recognized the Company’s diwani rights—revenue collection—in exchange for annual payments. Shuja‑ud‑Daulah ceded strategic territories and agreed to war indemnities. These decrees legally handed fiscal control of rich provinces to the Company—turning them from traders into rulers.

9. Dual Government in Bengal (1765–72): Chaos in Collaboration

Clive initiated a dual governance system: the Company managed revenue (diwani), and the Nawab retained judicial and police powers (nizamat). Though occasional tensions emerged, revenue flowed into Company coffers. This hybrid structure fostered corruption, inefficiency, and widespread suffering—faced most severely by ordinary villagers who endured seizures, harassment, and neglect.

10. Expansion Tools of the East India Company

The Company spread its influence through carefully structured policies:

11. Structural Takeover & Political Consolidation

By 1765, Bengal, Bihar, and Orissa were firmly within Company control. Puppet Nawabs of Awadh and Carnatic survived in name only, as British power extended across India via a mix of agreements, alliances, and administrative mechanisms.

12. Why Bengal Mattered: Financial Engine & Colonial Keystone

Bengal’s fertile land, thriving industries, and access to ports made its governance a windfall for the Company. Revenue from Bengal funded expanded colonial campaigns—serving as the empire’s fiscal backbone for decades.

In summary, the British takeover of Bengal was neither immediate nor accidental—it was orchestrated through calculated policy, betrayal, and diplomatic maneuvering. From innocent farmans to complete diwani control, the Company’s path to dominance reshaped subcontinental history.
