Sumer

n. region of southern Mesopotamia which was the site of the earliest known civilization (located in what is now southern Iraq)

Sumer (or Šumer) was the earliest known civilization of the ancient Near East, located in lower Mesopotamia (modern Iraq), from the time of the earliest records in the mid 4th millennium BC until the rise of Babylonia in the late 3rd millennium BC. The term "Sumerian" applies to all speakers of the Sumerian language. Sumer, together with Ancient Egypt, and the Indus Valley Civilization, is considered among the first settled societies in the world to have manifested all the features needed to qualify fully as a "civilization".
