1. Political Context

  • Decline of the Mughal Empire: By the mid-18th century, the Mughal Empire, which had once dominated India, was in decline. The central authority weakened, leading to the rise of regional powers and a fragmented political landscape. This created opportunities for foreign powers, such as the British East India Company, to expand their influence.
  • Rise of Regional Powers: As the Mughal Empire weakened, various regional rulers, including the Nawab of Bengal, Siraj ud-Daula, began to assert their independence. Siraj ud-Daula became the Nawab in 1756 and was determined to maintain control over Bengal and resist foreign encroachments.
  • Tensions with the British East India Company: The British East India Company had established a significant presence in India, particularly in Bengal, where they engaged in trade and commerce. The Company’s growing power and influence were viewed with suspicion by local rulers, including Siraj ud-Daula.

2. Economic Context

  • Control of Trade: Bengal was one of the richest provinces in India, known for its lucrative trade in textiles, spices, and other goods. The British East India Company sought to monopolize this trade, which led to conflicts with local rulers who wanted to maintain their economic independence.
  • Revenue Collection: The British imposed heavy taxes and sought to control revenue collection in Bengal, which angered Siraj ud-Daula and other local merchants. This economic exploitation contributed to rising tensions between the Nawab and the Company.

3. Military Context

  • Fortification of Calcutta: The British fortified their trading post in Calcutta, which was seen as a direct challenge to Siraj ud-Daula’s authority. In response, the Nawab sought to assert his power and prevent the British from expanding their influence.

4. Key Events Leading to the Battle

  • Capture of Calcutta: In 1756, Siraj ud-Daula captured Calcutta, leading to the infamous incident known as the “Black Hole of Calcutta,” where British prisoners were allegedly confined in a small, overcrowded dungeon, resulting in many deaths. This event fueled British resentment and a desire for revenge.
  • Formation of Alliances: The British sought to undermine Siraj ud-Daula by forming alliances with discontented factions within his court, particularly Mir Jafar, who was unhappy with the Nawab’s rule. This internal betrayal played a crucial role in the outcome of the battle.
  • Preparations for War: The British, under the leadership of Robert Clive, prepared for military action to reclaim their lost territory and assert their dominance in Bengal. They gathered forces and strategized for the impending conflict.

The Battle of Plassey (1757)

Location: Palashi, a village in modern-day West Bengal, India.

Initial Movements:

  • Robert Clive, leading the British East India Company forces, advanced toward Murshidabad, the capital of Nawab Siraj-ud-Daulah.
  • The Nawab’s army numbered approximately 50,000 troops, including 16,000 cavalry and a contingent of around 50 French-officered field guns. In contrast, Clive’s smaller force included about 3,000 men—2,100 sepoys (Indian soldiers) and 800 European soldiers—with only 10 field guns.

Strategic Alliances:

  • The wealthy Jagat Seth banking family, previously supporters of the Nawabs, allied with Clive out of concern for potential disruptions to their profitable European trade if Siraj-ud-Daulah emerged victorious.

Battle Events:

  • The opposing armies met near Palashi. Initial exchanges of artillery fire had limited effect.
  • A sudden heavy rainstorm ensued, and while the British protected their gunpowder with tarpaulins, the Nawab’s troops did not, rendering their weapons ineffective.

  • Mir Jafar withheld his troops from joining the battle, weakening the Nawab’s defense and leaving one flank vulnerable.

Outcome:

  • The British captured the Nawab’s exposed artillery positions and launched an effective bombardment on the remaining forces. This led to a decisive shift in the battle’s momentum.
  • Siraj-ud-Daulah abandoned the battlefield, only to be captured and imprisoned by forces loyal to Mir Jafar. He was eventually executed.
  • British casualties were minimal, with 22 killed and 50 wounded, while the Nawab’s forces suffered around 500 deaths and numerous injuries.

Siraj Ud Daulah – Role in the Battle Of Plassey

  • End of Reign: Alivardi Khan passed away in 1756 before he could act on his apprehensions regarding European influence.
  • Successor: His grandson, Siraj-ud-Daulah, son of Alivardi’s youngest daughter, succeeded him and inherited these challenges.
  • Siraj ud Daulah led to the imprisonment of 146 English prisoners housed in a teeny-tiny room, due to this, 123 of them died from suffocation. A tragedy for Britishers is known as the “Black Hole Tragedy.”
  • The widespread abuse of trade privileges by the East India Company (EIC) adversely impacted it. 
  • Siraj ud Daulah’s hostility became apparent when they attacked and captured the English fort in Calcutta.

The Black Hole of Calcutta Incident (June 20, 1756)

The Black Hole of Calcutta was a significant event that took place on June 20, 1756, when a group of Europeans was imprisoned in Calcutta (now Kolkata), resulting in many deaths. These individuals were the last defenders of the city after its capture by Siraj al-Dawlah, the Nawab of Bengal. The East India Company’s garrison, under the leadership of John Z. Holwell, who declared himself the governor of Bengal, had surrendered.

  • The Background: The Nawab launched the attack on Calcutta due to the company’s continued fortification of the city, seen as a defensive measure in preparation for conflict during the Seven Years’ War (1756–63).
  • The Imprisonment: Following the city’s surrender, Holwell and the surviving Europeans were confined overnight in a small room intended for petty offenders, known as the Black Hole. This space measured only 18 feet by 14 feet (approximately 5.5 by 4 meters) and had only two small windows for ventilation.
  • Reported Details: Holwell claimed that 146 people were crammed into the room, with only 23 surviving by morning. This account was later used to exemplify British resilience and to portray the Nawab as ruthless.
  • Reevaluation: By 1915, British schoolmaster J.H. Little questioned Holwell’s reliability, citing inconsistencies in the account. It emerged that the Nawab’s involvement might have been due to oversight rather than deliberate cruelty. A 1959 study by historian Brijen Gupta indicated that while the incident did occur, the number of those confined was closer to 64, with 21 survivors.

This reexamination shifted the perception of the event, showing that many details were exaggerated, altering its role as a symbol of British imperial rhetoric.

Mir Jafar and the Treaty of 1760 after the Battle of Plassey

Mir Jafar became increasingly discontented with Robert Clive’s meddling after assuming the role of Nawab of Bengal.

His downfall ensued when he conspired with the Dutch at Chinsura, resulting in their humiliation at Bedara in 1759 when English forces defeated them. The English, angered by Mir Jafar’s treachery and failure to honour payments owed to the East India Company, sought retribution.

Amidst this turmoil, the passing of Mir Jafar’s son, Miran, ignited a succession struggle for the nawabship of Bengal between Mir Kasim, Mir Jafar’s son-in-law, and Miran’s offspring.

Following negotiations, a treaty between the Company and Mir Kasim was brokered in 1760 by Calcutta’s new Governor, Vansittart. Its key provisions included the cession of districts to the Company, a share in Sylhet’s chunam trade, debt repayment, financial contributions to the Company’s campaigns in southern India, and mutual defence agreements.

Under mounting pressure from the Company, Mir Jafar resigned in favour of Mir Kasim, receiving an annual pension of Rs 1,500.
