One reason that the Battle of Buxar was a turning point in the History of India was that it marked a new and unprecedented level of British control on the subcontinent. With the decisive and forceful nature of British victory in the Battle of Buxar, British interests now spread across a significant portion of the subcontinent. With the conclusion of the battle, the East India Company ended up controlling the state of Bengal and expanding its influence all the way into Delhi. The collection of revenue from Bengal added to the power and dominance of British interests in India.
This marked a turning point in Indian history because it began to generate widespread discontent. The British reading of the Battle was one of unprecedented victory and gargantuan control of India. This was myopic because such a wide level of British control served to unify many different factions of Indian society under one cause: To defeat Britain. It was here in which the Battle of Buxar could be seen as a turning point as it helped to begin the process of galvanizing India against the British.
