As we've talked about in multiple videos, some of the earliest civilizations we have found have been around river valleys. And that is no coincidence because some of the first agriculture emerged around river valleys, and the agriculture supported higher population densities and more sedentary populations and allowed for more specialization. And we have talked about several of these, the ancient Egyptians around the Nile River, the ancient Mesopotamians around the Tigris and Euphrates. And now we're gonna talk about the ancient civilization around the Indus River. The Indus River runs mostly in modern day Pakistan. And that's why it's called the Indus Valley Civilization.
