Persian language in the Indian subcontinent
The Persian language in the Indian subcontinent, before the British colonized the Indian subcontinent, was the region's lingua franca and a widely used official language. The language was brought into the Indian subcontinent by various Turkic and Afghan dynasties, in particular the Turko-Afghan Delhi Sultanate and the Mughal Dynasty. Persian held official status in the court and the administration within these empires and it heavily influenced many of the local languages, particularly the Urdu dialect of Hindustani.
