Mir Qasim was the Nawab of Bengal from 1760 to 1763. He was installed as Nawab with the support of the British East India Company, replacing Mir Jafar, his father-in-law, who had himself been supported earlier by the East India Company after his role in winning the Battle of Plassey for the British. However, Mir Jafar eventually ran into disputes with the East India Company and attempted to form an alliance with the Dutch East India Company instead. The British eventually defeated the Dutch at Chinsura and overthrew Mir Jafar, replacing him with Mir Qasim. Qasim too later fell out with the British and fought against them at Buxar. His defeat has been suggested as a key reason in the British becoming the dominant power in large parts of North and East India.
