After the Indian independence in August 1947, the former British province of Madras Presidency was renamed Madras State. Following states reorganizations in 1953 and 1956, the present state boundaries emerged. It was officially renamed Tamil Nadu in 1969. In 1956, Madras State was made up of 13 districts: Chingleput, Coimbatore, Kanyakumari, Madras, Madurai, Nilgiris, North Arcot, Ramanathapuram, Salem, South Arcot, Thanjavur, Tiruchirappalli, and Tirunelveli.
