In what ways has the meaning of the term ‘Hindustan’ charged over the centuries?

The meaning of the term ‘Hindustan’ has changed over the centuries in the following manner:

1. In the thirteenth century Minhaj-i-Siraj used the term ‘Hindustan’. He meant areas of Punjab, Haryana and the lands between Ganga and Yamuna. He used this term in a political sense that were a part of the dominions of the Delhi Sultanate. The term never included South India.
2. In the sixteenth century poet Babur used the term ‘Hindustan’ to describe the geography, the fauna and the culture of the inhabitants of the subcontinent.
