Explanation:

The Sumerians were the people of southern Mesopotamia whose civilization flourished between c. 4100-1750 BCE. Their name comes from the region which is frequently – and incorrectly – referred to as a “country”. Sumer was never a cohesive political entity, however, but a region of city-states each with its own king. Sumer was the southern counterpart to the northern region of Akkad whose people gave Sumer its name, meaning “land of the civilized kings”. The Sumerians themselves referred to their region simply as “the land” or “the land of the black-headed people”.
