Linguistic rights
The constitution of India was first drafted on January 26, 1950. It is estimated that there are about 1500 languages in India. Article 343–345 declared that the official languages of India for communication with centre will be Hindi and English. There are 22 official languages identified by constitution. Article 345 states that "the Legislature of a state may by law adopt any one or more of the languages in use in the State or Hindi as the language or languages to be used for all or any of the official purposes of that State: Provided that, until the Legislature of the State otherwise provides by law, the English language shall continue to be used for those official purposes within the State for which it was being used immediately before the commencement of this Constitution".
Anti-Hindi agitations of Tamil Nadu
The adoption of an official language for the Indian Republic was a hotly debated issue during the framing of the Indian Constitution after India's independence from the United Kingdom. After an exhaustive and divisive debate, Hindi was adopted as the official language of India with English continuing as an associate official language for a period of fifteen years, after which Hindi would become the sole official language. The new Constitution came into effect on 26 January 1950. Efforts by the Indian Government to make Hindi the sole official language after 1965 were not acceptable to many non-Hindi Indian states, who wanted the continued use of English. The Dravida Munnetra Kazhagam (DMK), a descendant of Dravidar Kazhagam, led the opposition to Hindi. To allay their fears, Prime Minister Jawaharlal Nehru enacted the Official Languages Act in 1963 to ensure the continuing use of English beyond 1965. The text of the Act did not satisfy the DMK and increased their skepticism that his assurances might not be honoured by future administrations.
