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.

After the war Japan was under U.S. occupation and India gained its independence on August 15, 1947. In 1951, the San Francisco Peace Conference was held with Indian Prime Minister Jawaharlal Nehru refusing to attend the conference, because he considered the provisions of the San Francisco Treaty to be limiting Japanese sovereignty.
