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.
Constitutional autochthony
Independence was formally granted to India by the enactment of the Indian Independence Act 1947 though the executive decision to grant India independence was arrived at earlier in the Cabinet Mission Plan in 1946. It was under this Plan that the Constituent Assembly was envisaged and charged with the mandate of drafting the new Constitution for India. This was legally recognised in Section 8 of the Independence Act. The Cabinet Mission Plan had envisaged that the new Constitution would be put to the Crown-in-Parliament for approval.
