What was the first name for the Indians?

The Republic of India has two principal short names in both official and popular English usage, each of which is historically significant, "India" and "Bharat". The first article of the Constitution of India states that "India, that is Bharat, shall be a union of states," implicitly codifying "India" and "Bharat" as equally official short names for the Republic of India. A third name, "Hindustan", is sometimes an alternative name for the region comprising most of the modern Indian states of the subcontinent when Indians speak among themselves. The usage of "Bharat", "Hindustan", or "India" depends on the context and language of conversation.
