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 South India
On August 15, 1947, the former British India achieved independence as the new dominions of India and Pakistan. The rulers of India's princely states acceded to the government of India between 1947 and 1950, and South India was organized into a number of new states. Most of South India was included in Madras state, which included the territory of the former Madras Presidency together with the princely states of Banganapalle, Pudukkottai, and Sandur. The other states in South India were Coorg (the erstwhile Coorg province of British India), Mysore State (the former princely state of Mysore) and Travancore-Cochin, formed from the merger of the princely states of Travancore and Cochin. The former princely state of Hyderabad became Hyderabad State, and erstwhile Bombay Presidency became Bombay State.
