The Battle of Buxar was fought on 22-23 October 1764, between the forces under the command of the British East India Company, led by Hector Munro, and the combined armies of Mir Qasim, Nawab of Bengal till 1764; the Nawab of Awadh Shuja-ud-Daula; and the Mughal Emperor Shah Alam II. The battle resulted in the 1765 Treaty of Allahabad, in which the Mughal Emperor surrendered sovereignty of Bengal to the British.
