India has very old links with the Arab world, and with Persia. For hundreds of years starting in the 11th century, large parts of northern India were ruled by dynasties with roots in that part of the world; the language of the Mughal court was Persian, and so on. This is all well-known, as is the existence of many loan-words from Farsi, Arabic, and Turkish in Hindi/Urdu, the lingua franca of much of northern India and Pakistan.
