India
India is home to two major language families: Indo-Aryan (spoken by about 74% of the population) and Dravidian (spoken by 24% of the population). Other languages spoken in India come from the Austroasiatic and Sino-Tibetan language families. India has no national language. Hindi, with the largest number of speakers, is the official language of the government. English is used extensively in business and administration and has the status of a "subsidiary official language"; it is important in education, especially as a medium of higher education. Each state and union territory has one or more official languages, and the constitution recognises in particular 22 "scheduled languages".
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.
