Languages with official status in India
The Constitution of India designates the official language of the Government of India as Hindi written in the Devanagari script, as well as English. There is no national language as declared by the Constitution of India. Hindi is used for official purposes such as parliamentary proceedings, judiciary, communications between the Central Government and a State Government. States within India have the liberty and powers to specify their own official language(s) through legislation and therefore there are 22 officially recognized languages in India of which Hindi is the most used. The number of native Hindi speakers is about 25% of the total Indian population; however, including dialects of Hindi termed as Hindi languages, the total is around 44% of Indians, mostly accounted from the states falling under the Hindi belt. Other Indian languages are each spoken by around 10% or less of the population.
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.
