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]
British Raj This system of governance was instituted on 28 June 1858, when, after the Indian Rebellion of 1857, the rule of the British East India Company was transferred to the Crown in the person of Queen Victoria[12] (who, in 1876, was proclaimed Empress of India). It lasted until 1947, when Britainâ€²s Indian Empire was partitioned into two sovereign dominion states: the Dominion of India (later the Republic of India) and the Dominion of Pakistan (later the Islamic Republic of Pakistan, the eastern part of which, still later, became the People's Republic of Bangladesh). At the inception of the Raj in 1858, Lower Burma was already a part of British India; Upper Burma was added in 1886, and the resulting union, Burma, was administered as an autonomous province until 1937, when it became a separate British colony, gaining its own independence in 1948.
