The Battle of Plassey was fought on June 23, 1757 between the British East India Company led by Robert Clive and Siraj-ud-Daulah, the Nawal of Bengal. This decisive victory, achieved through treachery and strategic alliances, marked the beginning of British political and economic control over the Indian subcontinent. The year 1857 refers to the Indian Rebellion, while 1754 and 1756 are incorrect.
