History of Tamil Nadu districts

After Indian independence in August 1947, the former British province of Madras Presidency became Madras State, renamed Tamil Nadu in 1968. The three princely states of Sandur, Banganapalle, and Pudukkottai were merged into Bellary, Kurnool, and Thiruchirapalli districts, respectively. In 1953 the eleven northern districts of Madras State became the new state of Andhra Pradesh, and Bellary District was divided between Andhra Pradesh and Mysore State (present-day Karnataka). Tamil Nadu acquired its present boundaries on 1 November 1956, when Dakshina Kannada and Malabar districts were ceded to Mysore and Kerala states, respectively, and Kanyakumari District of erstwhile Travancore-Cochin state was ceded to Madras State.

In 1956, Madras State was made up of 13 districts: Chengalpattu, Coimbatore, Kanyakumari, Madras, Madurai, The Nilgiris, North Arcot, Ramanthapuram, Salem, South Arcot, Thanjavur, Tiruchirappalli, and Tirunelveli.
