History of the British Raj
The history of the British Raj refers to the period of British rule on the Indian subcontinent between 1858 and 1947. The system of governance was instituted in 1858 when the rule of the East India Company was transferred to the Crown in the person of Queen Victoria (who in 1876 was proclaimed Empress of India). It lasted until 1947, when the British provinces of India were partitioned into two sovereign dominion states: the "Dominion of India" and the "Dominion of Pakistan", leaving the princely states to choose between them. The two new dominions later became the Republic of India and the Islamic Republic of Pakistan (the eastern half of which, still later, became the People's Republic of Bangladesh). The province of Burma in the eastern region of the Indian Empire had been made a separate colony in 1937 and became independent in 1948.
History of the Telangana movement
When India became independent from the British Empire in 1947, the Nizam of Hyderabad, a Muslim king, wanted Hyderabad State to remain independent under the special provisions given to princely states. The Hindus of the Hyderabad State who accounted for 93% of its population, launched the 'Join India' movement with the cooperation of a few Muslims for the integration of the State with the rest of the country. The Indian National leaders from the state as well as Arya Samaj leaders invoked themselves whole-heartedly in the movement. The peasants of the state, influenced by Communist party, had also revolted against the Nizam, who tried to suppress their armed struggle against landlords. Qasim Razvi led private Razakar Muslim army fighting for continuation of the Nizam's rule, did worst forms of atrocities on people. The Government of India liberated and assimilated the Hyderabad State on 17 September 1948, in an operation by the Indian Army called Operation Polo.
