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.

On 13 August 1920, King-Emperor George V issued the required Order in Council. Until India became independent in 1947, the post was styled "High Commissioner for India". The first High Commissioner for India was Indian Civil Service officer Sir William Stevenson Meyer; the first of Indian origin was Sir Dadiba Merwanji Dalal. The High Commissioner enjoyed the same status as his counterparts from the British Dominions. Upon Indian independence, the post was given the present designation.
