For those interested in an overview of the history of the area in an historic dramatic frame of reference I can recommend the group of short stories published as Life Along the Silk Road by Susan Whitfield.
Only in the sense that Europe is an inalienable part of India.
"Hi I'm infinity and I... I cracked and generated a self-replicating biology last aeon. By the second kalpa they'd devised a writing system and started battling each other for spacetime. I've got to stop doing that."
"Yeah, well, more than most of the others, but..."
"Are you not going to do something about that?"
"Nah, I hope it's self-terminating. Should eventually cancel itself."
"You hope?"
"Look, don't ruin this for me okay, nothing ever happens on your planets and look at ALL THIS BLOOD"
Our current best understanding of the archaeological, linguistic, and genetic evidence (and the genetic evidence in particular became available only in the past 20 years or so), suggests that the archeological culture we label the Sintashta (https://en.wikipedia.org/wiki/Sintashta_culture), who flourished on the central Asian steppes c. 2000 BC, almost certainly spoke the language we reconstruct as Proto-Indo-Iranian (that is, the descendant of Proto-Indo-European ancestral to the modern Indian and Persian languages), likely used the term "Arya" as some kind of self-designation - and when their ethno-linguistic descents showed up on the Indian subcontinent in the mid-2nd-millennium BC, this probably mostly felt like a violent invasion from the perspective of the non-Indo-European-speaking peoples already inhabiting the region.
In other words, pretty much every modern Indian or Iranian person is in fact a descendant of an ancient people we can reasonably call the Aryans even if "Sintashta culture" is a more precise archaeological term; and this is the case regardless of what Adolf Hitler thought about how this applied to ethnic Germans in his day.
