What was Mesopotamia divided into?

Mesopotamia was primarily divided into two main regions: Sumer in the south and Akkad in the north. Sumer consisted of city-states like Ur, Uruk, and Eridu, while Akkad was known for its empire under leaders like Sargon. Additionally, the region included other areas such as Assyria to the north and Babylonia in the central part, each with distinct cultures and political entities. This division contributed to the rich tapestry of civilizations that flourished in ancient Mesopotamia.
