What is the Battle of Plassey?

The Battle of Plassey was fought on 23 June 1757 at Palashi (Plassey), on the banks of the Bhagirathi River in Bengal. It was a decisive engagement between the forces of the British East India Company under Robert Clive and the Nawab of Bengal, Siraj-ud-Daulah, along with his French allies. Despite being vastly outnumbered — Siraj-ud-Daulah commanded roughly 50,000 troops, 40 cannons, and 10 war elephants against Clive's approximately 3,000 soldiers — the British won through a conspiracy. Clive had bribed Mir Jafar, the Nawab's commander-in-chief, who betrayed Siraj-ud-Daulah by keeping his forces inactive during the battle.

The victory transformed the East India Company from a trading enterprise into a political and military power in India. After the battle, Mir Jafar was installed as the puppet Nawab of Bengal, and the Company gained effective control over Bengal's vast revenues. Historians conventionally mark 1757 as the beginning of British political dominion in India.
