Is the word "India" as a region/country or "Aryan" as a proper name of a race even mentioned in Veda to get their history from Vedas as a source? I did not read them in Yajurveda while reading it. If yes, please quote from Yajurveda.
I have not read YajurVeda thoroughly, so I would not know. However, the name of the River Indus (Sindhu) is frequently mentioned in RigVeda.The Chinese called us 'Intu' in history and the Greeks called us 'Indoi' (Hindvi - of the region of Sindhu/Indus). Arabs also knew the word, that is why they have a name like Al-Hindi. India derives from a corruption of Sindhu/Indus.
"‘Ala al-Din ‘Ali ibn ‘Abd-al-Malik Husam al-Din al-Muttaqi al-Hindi (died 1567 CE/975 AH) was a Sunni Islamic scholar who is known for writing '
Kanz al-‘Ummāl fī sunan al-aqwāl wa'l af‘āl)'. The book is a collection of Islamic Hadith. Al-Hindi was born in Burhanpur, India."

2. That I to all the people may address this salutary speech,
To priest and nobleman, Sûdra and Arya, to one of our own kin and to the stranger.
Dear may I be to Gods and guerdon-giver. Fulfilled be this my hope: be that my portion!
