Now, the Akkadians rule for a little over 100 years. And then you have several other empires. And it can get confusing. The way I've structured this timeline is this top line right over here is southern Mesopotamia, and this bottom line right over here is northern Mesopotamia. So this orange shows you where the Sumerians were reigning. Some people think that they might have been the first empire. This bottom line here, you can see the Akkadian speakers, but they were fragmented until you have Sargon the Great establishing the Akkadian Empire.
