who introduced dual system of administration in bengal
Nawabs of Bengal and Murshidabad In 1765, Robert Clive, of the British East India Company, became the first British Governor of Bengal.[37] He secured in perpetuity for the Company the Diwani (revenue and civil justice) of the then Bengal subah from the then Mughal Emperor, Shah Alam II and thus the system of Dual Government was established and the Bengal Presidency was formed. In 1772 the Dual Government system was abolished and Bengal was brought under direct control of the British. In 1793, when the Nizamat (military power and criminal justice) of the Nawab was also taken away from them, they remained as the mere pensioners of the British East India Company. After the Revolt of 1857, Company rule in India ended and the British Crown took over the territories which were under the direct rule of the British East India Company in 1858, which marked the beginning of the British Raj. These territories, including the territory of the Nawab Nazims came under the direct rule of the British Crown and British Raj was established in India. Thus, the Nawab Nizams remained just the titular heads of their territory, which was now ruled by the British Crown, and they had no political or any other kind of control over the territory.[38][39] The last Nawab of Bengal, Mansoor Ali Khan abdicated on 1 November 1880 in favour of his eldest son.[40]
Partition of Bengal (1905) Due to these political protests, the two parts of Bengal were reunited on 12 December 1911. A new partition which divided the province on linguistic, rather than religious grounds followed, with the Hindi, Oriya and Assamese areas separated to form separate administrative units: Bihar and Orissa Province was created to the west, and Assam Province to the east. The administrative capital of British India was moved from Calcutta to New Delhi as well.
