The Battle of Plassey, fought in 1757, was a decisive victory for the British East India Company over the Nawab of Bengal. The battle established Company rule in South Asia and marked the beginning of British imperial dominance on the subcontinent. Though the Nawab had greater numbers, the British were able to conspire with disaffected Bengal army leaders to ensure the Nawab's defeat. The victory transformed the East India Company from a trading organization into a territorial power and heralded major economic and political changes in the region.
