Sumer was located in the southernmost region of ancient Mesopotamia, situated between the Tigris and Euphrates rivers. This area, which corresponds to modern-day southern Iraq, extended from the vicinity of Baghdad down to the Persian Gulf.1
Historically, this territory later became known as Babylonia. The region was characterized by a collection of independent city-states, such as Ur, Uruk, and Nippur, which served as the foundation for the earliest known civilization.12
