Tamil Nadu Day After India gained independence on 15 August 1947, the Madras Province became the Madras State. The boundaries of the state were reorganized linguistically as a result of the States Reorganization Act of 1956. The state of Tamil Nadu was formed on 1 November 1956 as the Madras State. On 18 July 1967, the state assembly passed a resolution moved by former Chief Minister C.N. Anna Durai to change the name of the then Madras Province to Tamil Nadu. Traditionally, 1 November is observed as the State Reorganization Day.
