Post-independence
India became independent from the United Kingdom in 1947. The Muslim Nizam of Hyderabad wanted to retain his independence from India, he was forced accede his state to India in 1948 as the Hyderabad State. When India became independent, the Telugu-speaking people (although Urdu is spoken in some parts of Hyderabad and in few other districts of Telangana) were distributed in about 22 districts, 9 of them in the Telangana region of Nizam's Dominions (Hyderabad State) and 12 in the Madras Presidency and one in French controlled Yanam. Andhra State was the first state in India that has been formed on a purely linguistic basis by carving it out from Madras Province in 1953. Andhra State was later merged with Telugu speaking area of Hyderabad (Telangana) to create Andhra Pradesh state in 1956. In 1954, Yanam (India) was liberated and it was merged with Pondicherry in 1963.
