The administrative evolution of Tamil Nadu dates back to the British colonial era when the Madras Presidency was subdivided into districts for efficient governance. After India’s independence, the state of Tamil Nadu was formed in 1956 and renamed in 1969 from Madras State. Initially, there were only 13 Districts of Tamil Nadu, but with the increasing population and administrative needs, several new districts were carved out over the years. The most recent district reorganization occurred in 2019, when new districts like Tenkasi, Kallakurichi, and Chengalpattu were created.
