Hello what can you tell me about Mesopotamia?
Hello there. Mesopotamia, meaning "land between rivers", is a historical region in the Middle East. Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BC.
what can you tell me about the government there?
My access to information about their government is not available right now but I can try to help you with some other information like the fact that along with Sumerian, Semitic languages were also spoken in early Mesopotamia.
wow do you have information about their history?
Historically important cities in Mesopotamia included Uruk, Ur, Nippur, Nineveh, and Babylon. Some of the important historical Mesopotamian leaders were Ur-Nammu, Sargon of Akkad, Hammurabi, and Tiglath-Pileser I.
Is there anything else you can tell me?
Mesopotamia is the place where the wheel was first used.
wow really. That is so cool. Tell me more please
In AD 226, the eastern regions of Mesopotamia fell to the Sassanid Persians.
Do you have any information on economy and agriculture?
Yes, the Tigris and Euphrates River valleys from the northeastern portion of the Fertile Crescent, which also included the Jordan River valley and that of the Nile.
tell me more
The need for irrigation led the Sumerians, and later the Akkadians, to build their cities along the Tigris and Euphrates and the branches of these rivers.

Not sure if it's fun but the in the extreme south, the Euphrates and the Tigris unite and empty into the Persian Gulf.
