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.
Partition of Bengal (1947)
The partition, with the power transferred to Pakistan and India on 14–15 August 1947, was done according to what has come to be known as the "3 June Plan" or "Mountbatten Plan". India's independence on 15 August 1947 ended over 150 years of British influence in the Indian subcontinent. East Bengal later became the independent country of Bangladesh after the 1971 Bangladesh Liberation War.
