The first civilization that we have evidence of around modern day India and Pakistan is the Indus Valley Civilization. And it's right around the Indus River in modern day Pakistan and northwest India. And in other videos we talk about how it really comes into being in the third millennium BCE and as we enter into the second millennium BCE it starts to decline. And we don't know exactly why it declined. Might have been climate change, drying up of a river, might have been a natural disaster, it might have been an influence of other peoples. And what we're gonna talk about in this video is the next significant period in the history of South Asia. And it involves the migration or the introduction of another group of people, we believe another group of people, and that's the Indo-Aryans.
