The Mughals had aided France during the Seven Years' War to avoid losing the Bengal region to the British. However, in the Battle of Plassey the British East India Company registered a decisive victory over the Nawab of Bengal and his French allies on 22 June 1757, under the leadership of Robert Clive. The battle followed the order of Siraj-ud-Daulah, the last independent Nawab of Bengal, to the English to stop the extension of their fortification. Robert Clive bribed Mir Jafar, the commander-in-chief of the Nawab's army, and also promised him to make him Nawab of Bengal which helped him to defeat Siraj-ud-Daulah and capture Calcutta.
