Mesopotamia

ancient name for the land that lies between the Tigris and Euphrates rivers (in modern Iraq), from Greek mesopotamia (khora), literally "a country between two rivers," from fem. of mesopotamos, from mesos "middle" (see medial (adj.)) + potamos "river" (see potamo-).

In 19c. the word sometimes was used in the sense of "anything which gives irrational or inexplicable comfort to the hearer," based on the story of the old woman who told her pastor that she "found great support in that comfortable word Mesopotamia" ["Brewer's Dictionary of Phrase & Fable," 1870]. The place was called Mespot (1917) by British soldiers serving there in World War I. Related: Mesopotamian.

A region of western Asia, in what is now Iraq, known as the “cradle of civilization.” Western writing first developed there, done with sticks on clay tablets. Agricultural organization on a large scale also began in Mesopotamia, along with work in bronze and iron (see Bronze Age and Iron Age). Governmental systems in the region were especially advanced (see Babylon (see also Babylon) and Hammurabi). A number of peoples lived in Mesopotamia, including the Sumerians, Akkadians, Hittites, and Assyrians.
