Telangana
When India became independent from the British Empire in 1947, the Nizam of Hyderabad did not want to merge with the Indian Union and wanted to remain independent. The Government of India annexed Hyderabad State on 17 September 1948 after a military operation called Operation Polo. It appointed a civil servant, M. K. Vellodi, as first chief minister of Hyderabad State on 26 January 1950. He administered the state with the help of English-educated bureaucrats from the Madras and Bombay states, who were familiar with British systems of administration unlike the bureaucrats of Hyderabad State who used a completely different administrative system. The official language of the state was switched from Urdu to English.
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.
