On 23 June 1757, a small Company army under Robert Clive met the huge army of Siraj-ud-Daulah, the Nawab of Bengal. The fight was short. Most of the Nawab's troops never fought, because his commander Mir Jafar had secretly joined the British. After Plassey, a trading company became the real power in Bengal, the richest province of India.
Bengal and the English before 1757
A rich province, a new Nawab, and a company that wanted more.
Bengal then meant Bengal, Bihar and Orissa together. It was the richest province of the Mughal Empire. It sold cloth, silk, saltpetre and sugar to the world. The Nawab of Bengal ruled it from Murshidabad. He was in name a governor of the Mughal emperor, but in practice he was free.

A dastak was a free pass for the Company's goods. A Company officer signed it, and the Nawab's men let the goods pass without duty. The 1717 farman meant this only for the Company's own trade. But Company servants used dastaks for their private trade too. Some even sold them to Indian merchants. The Nawab lost a lot of tax money.
Why Siraj and the Company fought
Trade passes, a new fort, and a Nawab who would not bend.
Siraj-ud-Daulah was only in his twenties. Some of his own relatives and nobles wanted someone else on the throne. The English did not come to greet the new Nawab with gifts, as custom expected. Soon the two sides were quarrelling over money and respect.
| Cause | What happened |
|---|---|
| Misuse of dastaks | Company servants used the duty-free passes for private trade and sold them. The Nawab lost customs income. |
| New fortification | The English strengthened Calcutta's defences without the Nawab's permission. They were preparing for war with the French. |
| Shelter to Krishna Das | The Company gave shelter to Krishna Das, who had fled with treasure. The Nawab wanted him handed back. |
| A young, unsure Nawab | Rivals inside his own court disliked Siraj. The British later used these men against him. |

After Calcutta fell, British prisoners were locked overnight in a small guard-room called the Black Hole. J. Z. Holwell, a survivor, wrote that 146 went in and 123 died. Many historians now think the real numbers were much smaller. In exams, remember: the incident is linked to 1756 and to Siraj-ud-Daulah, and it came before Plassey.

The battle: 23 June 1757
Won by a plot more than by guns.
The armies met near Palashi (Plassey), a village on the Bhagirathi river. It lies in today's Nadia district of West Bengal, south of Murshidabad. The name is said to come from the red-flowered palash trees that grew there.
Commander of the Nawab's army. Promised the throne by Clive.
Led a large part of the army. Also kept his men out of the fight.
The richest banking house of Bengal. Backed the plot with money and influence.
Helped carry messages. Clive tricked him with a fake copy of the treaty.
The men in the plot against Siraj.
Clive did not win with better soldiers. He won by buying the Nawab's generals. Mir Jafar, Rai Durlabh and Yar Lutf Khan kept their troops out of the battle. Only Mir Madan and Mohan Lal fought hard. When Mir Madan was killed by a cannon ball, Siraj lost heart and fled. That is why Plassey is called a victory of conspiracy, not of arms.
A heavy monsoon shower fell during the battle. Clive's men covered their gunpowder. Much of the Nawab's powder got wet. When the Nawab's horsemen charged, thinking the British guns were wet too, they were cut down. Only about 22 of Clive's men were killed.

What Plassey changed
A puppet Nawab, a rich Company, and the road to Buxar.
Siraj fled to Murshidabad and then tried to escape north. He was caught and killed on 2 July 1757 on the orders of Miran, Mir Jafar's son. Mir Jafar became Nawab. But he owed his throne to the Company, and he could refuse it nothing.
- A puppet Nawab. Mir Jafar ruled in name. The real power in Bengal was now the Company.
- Huge payments. Mir Jafar paid the Company and its officers enormous sums. Clive himself became very rich.
- Land and trade. The Company got the zamindari of the 24 Parganas near Calcutta, and its free trade rights were confirmed.
- The French pushed out. With Chandernagore gone, the French lost their power in Bengal.
- Money for more wars. Bengal's wealth helped the Company fight its rivals elsewhere in India.
- 1757: Mir Jafar made NawabHe cannot meet the Company's demands for money.
- New Nawab1760: Mir Qasim replaces himThe Company puts Mir Jafar's son-in-law, Mir Qasim, on the throne.

Why is the Battle of Plassey called a victory of conspiracy rather than of arms?
Show answer
Clive had secretly promised Mir Jafar, the Nawab's army chief, the throne of Bengal. On the day, Mir Jafar, Rai Durlabh and Yar Lutf Khan kept their troops out of the fight. Most of the Nawab's 50,000 men never fought, so Clive's 3,000 won.
