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.

The partition of India was set forth in the Indian Independence Act 1947 and resulted in the dissolution of the British Indian Empire and the end of the British Raj. It resulted in a struggle between the newly constituted states of India and Pakistan and displaced up to 12.5 million people with estimates of loss of life varying from several hundred thousand to a million (most estimates of the numbers of people who crossed the boundaries between India and Pakistan in 1947 range between 10 and 12 million). The violent nature of the partition created an atmosphere of mutual hostility and suspicion between India and Pakistan that plagues their relationship to this day.
The partition included the geographical division of the Bengal province into East Bengal, which became part of the Dominion of Pakistan (from 1956, East Pakistan). West Bengal became part of India, and a similar partition of the Punjab province became West Punjab (later the Pakistani Punjab and Islamabad Capital Territory) and East Punjab (later the Indian Punjab, as well as Haryana and Himachal Pradesh). The partition agreement also included the division of Indian government assets, including the Indian Civil Service, the Indian Army, the Royal Indian Navy, the Indian railways and the central treasury, and other administrative services.
