It is a battle fought between the East India Company force headed by Robert Clive and Siraj-Ud-Daulah (Nawab of Bengal). The rampant misuse by EIC officials of trade privileges infuriated Siraj. The continuing misconduct by EIC against Siraj-Ud-Daulah led to the battle of Plassey in 1757.

Causes are:-

• The rampant misuse of the trade privileges given to the British by the Nawab of Bengal
• Non-payment of tax and duty by the workers of the British East India Company

Other reasons that supported the coming of this battle were:

• Fortification of Calcutta by the British without the Nawab’s permission
• Misleading Nawab on various fronts by British
• An asylum was provided to Nawab’s enemy Krishna Das
