Interesting thing is: The term ‘Aryan’ is the self-designated name of the Indo-Iranian people.
Actually in Sanskrit, the word “aryan” denoted a civilization that was advanced in morality, religion, good governance, and so on. “Anaryan” mean barbarian, uncultured, uncivilized, etc.
And the “aryan invasion” theory was invented by British and maybe some German indologists. Turns out it isn’t true.
