who declare bengal an independent state in 1771
Nawabs of Bengal and Murshidabad The Nawabs of Bengal (full title, the Nawab Nizam of Bengal and Orissa) were the rulers of the then provinces of Bengal and Orissa. Between 1717 and 1765, they served as the rulers of the subah (or province) of Bengal. However, they were only nominally subordinate to the Mughal Empire. Siraj ud-Daulah, the last independent Nawab of Bengal was betrayed in the Battle of Plassey by Mir Jafar. He lost to the British, who took over the charge of Bengal in 1757, installed Mir Jafar on the Masnad (throne) and established itself to a political power in Bengal.[2]
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.
