They are know by different names depending on who you ask: the Aryan people or the Brokpa (plus a couple more beside that in different dialects) and, depending who you ask, their origins go back 2500 years or more or less. I must have read more than a a dozen different articles, diatribes and references and while I’m still no wiser than i was before, one thing is for sure: the moment you cross the “border” and head into the Aryan valley in northern Ladakh, you are no longer in India. Regardless of what international political borders say and regardless of what the Indian government may believe.
