Of the 22 official languages, 15 are Indic, four are Dravidian, two are Tibeto-Burman, and one is Munda.
Linguistic history of India
The establishment of British rule in the subcontinent saw the clear division of Hindi and Urdu registers. This period also saw the rise of modern Hindi literature starting with Bharatendu Harishchandra. This period also shows further Sanskritization of the Hindi language in literature. Hindi is right now the official language in nine states of India— Uttar Pradesh, Bihar, Rajasthan, Jharkhand, Madhya Pradesh, Chhattisgarh, Uttarakhand, Haryana and Himachal Pradesh—and the National Capital Territory of Delhi. Post-independence Hindi became the official language of the Central Government of India along with English. Urdu has been the national and official language of Pakistan as well as the lingua franca of the country.
