Subdivisions |
The Indian state of Tamil Nadu is divided into 38 districts. Districts are the major administrative units of a state which are further sub-divided into taluks. There were 13 districts in the erstwhile Madras Province the boundaries of the present-day Tamil Nadu. Post the reorganization in 1956, Madras state had 13 re-organized districts which was further divided in the later years.
Before 1947, Madras Presidency under British Raj was made up of 26 districts, of which 12 districts were part of the boundaries of the present-day Tamil Nadu, namely, Chingleput, Coimbatore, Nilgiris, North Arcot, Madras, Madura, Ramnad, Salem, South Arcot, Tanjore, Tinnevely, and Trichinopoly. [1]
After Indian Independence, the Madras Presidency] became the Madras Province on 15 August 1947. Pudukottai, a princely state acceded to the Indian Union on 4 March 1948 and became a division in Trichinopoly district. [2] When the new constitution came into force on 26 January 1950, Madras Province became Madras State. Madras state included most of the present-day Tamil Nadu, Coastal Andhra and Rayalaseema of Andhra Pradesh, the Malabar region of Kerala, Bellary and South Canara districts of Karnataka. [3] Coastal Andhra and Rayalaseema were separated to form Andhra State in 1953. [4] As a result of the re-organization of states in 1956, South Canara and Bellary districts were merged with Mysore State to form Karnataka and Malabar district with the State of Travancore-Cochin to form Kerala in 1956. [5] The Tamil speaking regions of Kanyakumari which was earlier a part of Travancore-Cochin was merged to Madras state. [5] Madras state had 13 districts namely: Chingleput, Coimbatore, Kanyakumari, Madras, Madurai, Nilgiris, North Arcot, Ramanathapuram, Salem, South Arcot, Thanjavur, Tiruchirappalli and Tirunelveli.
