Languages with official status in India
Even though the English language is not included in the Eighth Schedule (as it is a foreign language), it is one of the official languages of the Union of India.
Of the 22 official languages, 15 are Indic, four are Dravidian, two are Tibeto-Burman, and one is Munda.
Hindi–Urdu controversy
Hindi is a literary register of the Hindustani language, derived from the Khariboli dialect of the Hindi languages. A Persianized variant of Hindustani began to take shape during the Delhi Sultanate (1206–1526 AD) and Mughal Empire (1526–1858 AD) in South Asia. Urdu, along with English, became the first official language of British India in 1850. Urdu was being written, spoken and translated to and from English in all courts, schools, official documents, and government institutes. Although the need to have a language for Hindus developed in the 1850s, the irrevocable momentum of the Hindi language movement occurred around 1880. Urdu is a name derived from the Turkic word "ordu" (army) or "orda". When the Turco-Persian Mughals who invaded the Indian subcontinent made camps, the colloquial Persian spoken by the soldiers, known as the "language of the camp", or ""Zaban-i-Ordu"", became gradually more and more Indianised, as they themselves settled and married into the local communities, until the dialect they spoke was readily intelligible to the native Hindu population.
