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 the British Raj
In 1935, after the failure of the Round Table Conferences, the British Parliament approved the Government of India Act 1935, which authorized the establishment of independent legislative assemblies in all provinces of British India, the creation of a central government incorporating both the British provinces and the princely states, and the protection of Muslim minorities. The future Constitution of independent India would owe a great deal to the text of this act. The act also provided for a bicameral national parliament and an executive branch under the purview of the British government. Although the national federation was never realized, nationwide elections for provincial assemblies were held in 1937. Despite initial hesitation, the Congress took part in the elections and won victories in seven of the eleven provinces of British India, and Congress governments, with wide powers, were formed in these provinces. In Great Britain, these victories were to later turn the tide for the idea of Indian independence.
