Post-Independence (1947–present)

After the Independence of India in 1947, the Madras Presidency became Madras state, comprising present-day Tamil Nadu and parts of Andhra Pradesh, Karnataka and Kerala. Andhra state was split from the state in 1953 and the state was further re-organized when states were redrawn linguistically in 1956 into the current shape. On 14 January 1969, Madras state was renamed Tamil Nadu, meaning "Tamil country". In 1965, agitations against the imposition of Hindi and in support of continuing English as a medium of communication arose which eventually led to English being retained as an official language of India alongside Hindi. After independence, the economy of Tamil Nadu conformed to a socialist framework, with strict governmental control over private sector participation, foreign trade, and foreign direct investment. After experiencing fluctuations in the decades immediately after Indian independence, the economy of Tamil Nadu consistently exceeded national average growth rates from the 1970s, due to reform-oriented economic policies. In the 2000s, the state has become one of the most urbanized states in the country with a higher Human Development Index compared to national average.
