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 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.
