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.
Bhutan–India relations
For much of its history, Bhutan has preserved its isolation from the outside world, staying out of international organisations and maintaining few bilateral relations. Bhutan became a protectorate of British India after signing a treaty in 1910 allowing the British to "guide" its foreign affairs and defence. Bhutan was one of the first to recognise India's independence in 1947 and both nations fostered close relations, their importance augmented by the annexation of Tibet in 1950 by the People's Republic of China and its border disputes with both Bhutan and India, which saw close ties with Nepal and Bhutan to be central to its "Himalayan frontier" security policy. India shares a border with Bhutan and is its largest trading partner, accounting for 98 percent of its exports and 90 percent of its imports.
