The region included the territories of undivided Bengal like West Bengal, Tripura, Orissa, Meghalaya, Bihar, Assam and modern Bangladesh. The Bengal Presidency proper was formed with the signing of the treaties of 1765 between the Nawab of Oudh, the Mughal Emperor and the authorities of the British East India Company. As a result of this the regions of Orissa, Bihar, Meghalaya and Bengal were placed under the administrative control of the British East India Company.
