British victory Great Britain The Battle of Buxar was fought between 22 and 23 October 1764, between the forces of the British East India Company, under the command of Major Hector Munro, and the combined armies of Balwant Singh, Maharaja of the Benaras State; Mir Qasim, Nawab of Bengal; Shuja-ud-Daula, Nawab of Awadh; and Shah Alam II, Emperor of the Mughal Empire.

[4] The battle was fought at Buxar, a "strong fortified town" within the territory of Bihar, located on the banks of the Ganges river about 130 kilometres (81 mi) west of Patna; it was a challenging victory for the British East India Company.

[5] The defeated Indian rulers were forced to sign the treaty, granting the East India Company Diwani rights, which allowed them to collect revenue from the territories of Bengal, Bihar, and Orissa on behalf of the Mughal emperor.

Mirza Najaf Khan reorganised formations around Shah Alam II, who retreated and then chose to negotiate with the victorious British.

Its aftermath witnessed significant shifts in power dynamics and set the stage for British dominance in the Bengal region.

The battle was the beginning of the end for the Mughal Empire's political control, as the Company continued to consolidate its influence over vast territories.
