This civilization existed around 5000-3500 BCE. The first city-states gradually develop in southern Mesopotamia. Mesopotamia lies between the two rivers, Tigris and Euphrates in southern Iraq. Some of the major Mesopotamian civilizations include the Sumerian, Assyrian, Akkadian, and Babylonian civilizations. The Sumerians were the first people to migrate to Mesopotamia, they created a good civilization. They invented writing and government. They were organized in city-states where each city had its own independent government ruled by a king that controlled the city and the surrounding farmland. Each city also had its own primary god. Sumerian writing, government, and culture would pave the way for other civilizations that will come after them.
