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.
Dominion of India
India was an independent dominion in the British Commonwealth of Nations with King George VI as the head of state between gaining independence from the United Kingdom on 15 August 1947 and the proclamation of a republic on 26 January 1950. It was created by the Indian Independence Act 1947 and was transformed into the Republic of India by the promulgation of the Constitution of India in 1950.
