<P> 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 . </P> <P> As the day (26 January 1965) of switching over to Hindi as sole official language approached, the anti-Hindi movement gained momentum in Madras State with increased support from college students . On 25 January, a full - scale riot broke out in the southern city of Madurai, sparked off by a minor altercation between agitating students and Congress party members . The riots spread all over Madras State, continued unabated for the next two months, and were marked by acts of violence, arson, looting, police firing and lathi charges . The Congress Government of the Madras State, called in paramilitary forces to quell the agitation; their involvement resulted in the deaths of about seventy persons (by official estimates) including two policemen . To calm the situation, Indian Prime Minister Lal Bahadur Shastri gave assurances that English would continue to be used as the official language as long as the non-Hindi speaking states wanted . The riots subsided after Shastri's assurance, as did the student agitation . </P> <P> The agitations of 1965 led to major political changes in the state . The DMK won the 1967 assembly election and the Congress Party never managed to recapture power in the state since then . The Official Languages Act was eventually amended in 1967 by the Congress Government headed by Indira Gandhi to guarantee the indefinite use of Hindi and English as official languages . This effectively ensured the current "virtual indefinite policy of bilingualism" of the Indian Republic . There were also two similar (but smaller) agitations in 1968 and 1986 which had varying degrees of success . </P> <P> The Republic of India has hundreds of languages . During the British Raj, English was the official language . When the Indian Independence Movement gained momentum in the early part of the 20th century, efforts were undertaken to make Hindustani as a common language to unite various linguistic groups against the British Government . As early as 1918, Mahatma Gandhi established the Dakshin Bharat Hindi Prachar Sabha (Institution for the Propagation of Hindi in South India). In 1925, the Indian National Congress switched to Hindustani from English for conducting its proceedings . Both Gandhi and Jawaharlal Nehru were supporters of Hindustani and Congress wanted to propagate the learning of Hindustani in non-Hindi speaking Provinces of India . The idea of making Hindustani or Hindi the common language, was not acceptable to Periyar, who viewed it as an attempt to make Tamils subordinate to North Indians . </P>
