The land between the Tigris and the Euphrates rivers is known as Mesopotamia, and it was the location of some of the earliest civilizations in the world. The Sumerians were one of the most important ones, and they were farming people. It is likely that the Sumerians were attracted to this land because of its fertility and its location between two rivers, which allowed them to irrigate the land, as well as obtain drinking water. This allowed them to sustain a large and complex society.
