Languages of India
Until the Twenty-first Amendment of the Constitution of India in 1967, the country recognised 14 official regional languages. The Eighth Schedule and the Seventy-First Amendment provided for the inclusion of Sindhi, Konkani, Meitei and Nepali, thereby increasing the number of official regional languages of India to 18. The Eighth Schedule of the Constitution of India, as of 1 December 2007, lists 22 languages, which are given in the table below together with the speaking population and the regions where they are used. 
The individual states, the borders of most of which are or were drawn on socio-linguistic lines, can legislate their own official languages, depending on their linguistic demographics. The official languages chosen reflect the predominant as well as politically significant languages spoken in that state. Certain states having a linguistically defined territory may have only the predominant language in that state as its official language, examples being Karnataka and Gujarat, which have Kannada and Gujarati as their sole official language respectively. Telangana, with a sizeable Urdu-speaking Muslim population, has two languages, Telugu and Urdu, as its official languages.
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.
