Explanation: The Diwani rights were a significant development in the history of British colonial rule in India. These rights were granted to the British East India Company by the Mughal Emperor Shah Alam II in 1765 through the Treaty of Allahabad. The Diwani rights allowed the Company to collect revenue from the territories of Bengal, Bihar, and Orissa, which were then known as the Bengal Subah.
The grant of Diwani rights was a pivotal moment in the consolidation of British power in India. Prior to this, the Company had been involved in trade and had limited administrative control over certain areas. The Diwani rights marked a shift from a purely commercial enterprise to a more direct form of governance and control over the revenue system of these regions.
The territories under the Diwani rights were strategically important. Bengal, in particular, was known for its fertile land and rich agricultural output, making it a significant source of revenue. Bihar and Orissa, while not as economically dominant as Bengal, were also important for their agricultural and mineral resources.
It is important to note that the Diwani rights did not include all of India. Other regions, such as Hyderabad and Awadh, were not part of the Diwani rights. These regions were under the control of local rulers who had their own agreements with the British East India Company.
The Diwani rights were a stepping stone towards the British East India Company's eventual control over much of India. The revenue collected from these territories was used to fund the Company's operations and to expand its influence further. The Diwani rights thus played a crucial role in the establishment of British colonial rule in India.
In summary, the correct answer is (D) Bengal, Bihar, and Orissa, as these were the territories specifically mentioned in the Diwani rights granted to the British East India Company. Understanding the historical context and the specific territories involved is essential to comprehending the significance of the Diwani rights in the broader narrative of British colonial rule in India.
