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.
President of India
India achieved independence from the British on 15 August 1947, initially as a dominion within the Commonwealth of Nations with George VI as king, represented in the country by a governor-general. Still, following this, the Constituent Assembly of India, under the leadership of B.R.Ambedkar, undertook the process of drafting a completely new constitution for the country. The Constitution of India was eventually enacted on 26 November 1949 and came into force on 26 January 1950, making India a republic. The offices of monarch and governor-general were replaced by the new office of President of India, with Rajendra Prasad as its first incumbent.
