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.
History of Andhra Pradesh
India became independent from the United Kingdom in 1947. Although the Muslim Nizam of Hyderabad wanted to retain independence from India, but was forced to cede his kingdom to the Dominion of India in 1948 to form Hyderabad State. Andhra, the first Indian state formed primarily on a linguistic basis, was carved from the Madras Presidency in 1953. In 1956, Andhra State was merged with the Telugu-speaking portion of Hyderabad State to create the state of Andhra Pradesh. The Lok Sabha approved the formation of Telangana from ten districts of Andhra Pradesh on 18 February 2014.
