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.

Eventually, in February 1947, Prime Minister Clement Attlee announced that the British government would grant full self-governance to British India by June 1948 at the latest. On 3 June 1947, the British government announced that the principle of division of British India into two independent states was accepted. The successor governments would be given dominion status and would have an implicit right to secede from the British Commonwealth. Viceroy Mountbatten chose 15 August, the second anniversary of Japan's surrender in the World War II, as the date of power transfer. He chose 14 August as the date of the ceremony of power transfer to Pakistan because he wanted to attend the ceremonies in both India and Pakistan.
