Again, these were the Akkadians under the Sargon of Akkad who invaded Sumer and the Sumerians and created the first empire good for him. But eventually those folks are going to be replaced around 2000 BCE by the Amorites. And the Amorites are going to overrun the Sumerians. They were a numeric kind of barbaric tribe that came in and are going to run the show now and they're going to make their capital at Babylon. And that's why they're known as Babylonians. And the Babylonians are going to last for about 500 years to about 1500 BCE. But their crowning achievement, their golden age around 1750 BCE is going to be when they had the leader Hammurabi.
