The great alluvial plain formed by the deposits of the Euphrates and Tigris rivers is known as the "Mesopotamian Plain." This region, often referred to as Mesopotamia, is historically significant and is located between the two rivers, which flow through modern-day Iraq.

The alluvial deposits from these rivers have nourished the land, making it one of the cradles of civilization, where agriculture thrived due to the fertile soil. This area was also vital for the development of early human societies, contributing to advancements in writing, architecture, and governance, and is often regarded as one of the earliest places of human civilization.
