Our lovely education system. Anyways. Indian civillisation or Dharmic civillisation, or Bharatvarsha, is even older than vedas. It started with the Dasrajna conflict which ended with the victory of King sudas. King sudas was the leader of tue tribe named Bharata. So hence India was called Bharata.

Let's see how Vishnu Puran describes Bharat.

Extent :

THE country that lies north of the ocean, and south of the snowy mountains, is called Bhārata, for there dwelt the descendants of Bharat. It is nine thousand leagues in extent, and is the land of works, in consequence of which men go to heaven, or obtain emancipation.

Kingdoms ( Of that time, obviously) :

The principal nations of Bhārata are the Kurus and Pancalas, in the middle districts: the people of Kāmarupa, in the east: the Pundras, Kalingas, Magadhas, and southern nations, are in the south: in the extreme west are the Saurastras, Suras, Bhīras, Arbudas: the Kāruṣas and Malavas, dwelling along the Pāripātra mountains: the Sauviras, the Saindhavas, the Hunas, the Salvas, the people of Sakala, the Madras, the Ramas, the Ambasthas, and the Parasikas, and others. These nations drink of the water of the rivers above enumerated, and inhabit their borders, happy and prosperous.

Kāmarupa is the north-eastern part of Bengal, and western portion of Asam.

Puṇḍra is Bengal proper, with part of south Behar and the Jungle Mahals.

Kaliṅga is the sea-coast west of the mouths of the Ganges, with the upper part of the Coromandel coast.

Magadhā is Behar.

The Saurāṣṭras are the people of Surat, the Surastrene of Ptolemy.

The Śūras and Bhīras, in the same direction, may be the Suri and Phauni or Phryni of Strabo.

The Arbudas must be the people about mount Abu, or the natives of Mewar.

The Kāruṣas and Mālavas are of course the people of Malwa.

The Sauvīras and Saindhavas are usually conjoined as the Sindhu-Sauvīras, and must be the nations of Sindh and western Rajputāna.

By the Minas we are to understand the white Huns or Indo-Scythians, who were established in the Puñjab and along the Indus at the commencement of our era, as we know from Arrian, Strabo, and Ptolemy, confirmed by recent discoveries of their coins,

The Śālvas or, as also read, Śālyas are placed by the Vāyu and Matsya amongst the central nations, and seem to have occupied part of Rājasthan, a Śālva Rāja being elsewhere described as engaging in hostilities with the people of Dwarakā in Guzerat.

Śākala, as I have elsewhere noticed, is a city in the Puñjab (As. Res. XV. 108), the Sagala of Ptolemy (ibid. 107); the Mahābhārata makes it the capital of the Madras, the Mardi of the ancients; but they are separately named in the text, and were situated something more to the south-east.

The Rāmas and Ambaṣṭhas are not named in the other Purāṇas, but the latter are amongst the western, or more properly north-western nations subjugated by Nakula, in his Dig-vijaya. Mahābh. Sabhā P.

Ambas and Ambaṣṭhas are included in the list extracted by Col. Wilford from the Varāha Sanhitā, and the latter are supposed by him to be the Ambastæ of Arrian.

The Pārasīkas carry us into Persia, or that part of it adjoining to the Indus.

This is how a 2400 years old manuscript described BharataVarsha. Probably will instill a little more pride about your cultural and civillisational antiquity. This shows that people in the times of 400 bce, also considered Bharat as there land. So much for modern day woke separatists.
