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".
Telangana
Telugu, one of the classical language of India is the official language of Telangana and Urdu is the second official language of the state. About 77% of the population of Telangana speak Telugu, 12% speak Urdu, and 13% speak other languages. Before 1948, Urdu was the official language of Hyderabad State, and due to a lack of Telugu-language educational institutions, Urdu was the language of the educated elite of Telangana. After 1948, once Hyderabad State joined the new Republic of India, Telugu became the language of government, and as Telugu was introduced as the medium of instruction in schools and colleges, the use of Urdu among non Hyderabadi Muslims decreased. Both Telugu and Urdu are used in services across the state, such as the Telangana Legislature website, with Telugu and Urdu versions of the website available, as well as the Hyderabad Metro, wherein both languages are used on station names and signs along with English and Hindi. The Urdu spoken in Telangana is called Hyderabadi Urdu, which in itself is a dialect of the larger Dakhini Urdu dialects of South India. Although the language is orally spoken by most Hyderabadi Muslims, the language in a literary context has long been lost, and standard Urdu is used.
