After winning the battle of Buxar, of which region Company became the real master?

The Battle of Buxar, fought on October 23, 1764, was a decisive military engagement that significantly altered the political landscape of India. The battle was fought between the forces of the East India Company, led by Major Hector Munro, and the combined armies of the Mughal Emperor Shah Alam II, the Nawab of Awadh, Shuja-ud-Daula, and the Nawab of Bengal, Mir Qasim. The East India Company emerged victorious, leading to a series of political and territorial changes in the region.

The immediate outcome of the battle was the Treaty of Allahabad, signed in 1765, which granted the East India Company the right to collect revenue (Diwani) in the provinces of Bengal, Bihar, and Orissa. This effectively made the East India Company the de facto ruler of the Bengal region, as it allowed the Company to control the economic resources of the area. The victory at Buxar marked the beginning of the Company's direct rule in Bengal, which was a crucial step in the expansion of British colonial power in India.

It is important to note that while the Battle of Buxar was a significant event, it did not result in the East India Company becoming the master of all of India. The Company's control was initially limited to the Bengal region, and it took several more years and battles for the Company to extend its influence across the subcontinent. The Company's victory at Buxar was a pivotal moment in the history of British colonialism in India, but it was part of a larger process of territorial expansion and consolidation of power.

The Battle of Buxar is often seen as a turning point in Indian history, marking the decline of Mughal power and the rise of British dominance in the region. The victory at Buxar and the subsequent Treaty of Allahabad laid the foundation for the East India Company's control over Bengal, which was a crucial step in the Company's broader strategy of establishing and maintaining its rule in India.
