Q. Who used the word "Hind" for India?
Answer: Amir Khusrau
Notes: The term “Hindustan” today we understand it as “India” the modern nation-state. When the term was used in the thirteenth century by Minhaj-i-Siraj, a chronicler who wrote in Persian, he meant the areas of Punjab, Haryana and the lands between the Ganga and Yamuna. He used the term in a political sense for lands that were a part of the dominions of the Delhi Sultan. In contrast, in the early sixteenth century Babur used Hindustan to describe the geography, the fauna and the culture of the inhabitants of the subcontinent. Later the fourteenth-century poet Amir Khusrau used the word "Hind". While the idea of a geographical and cultural entity like “India” did exist, the term “Hindustan” did not carry the political and national meanings which we associate with, today.
