So around 2350, you have Sargon establishing what might be the first dynastic empire in the world, the Akkadian Empire. And he was able to take control of both northern and southern Mesopotamia. So even the Sumerians were under the control of the Akkadians. And as we'll see over time, you have a lot of mixing between the Akkadian language, the Sumerian language. Akkadian gets written in the cuneiform script. And starting at around this period, Sumerian starts to die as a spoken language, and Akkadian really becomes dominant. Now, the Akkadians rule for a little over 100 years.
