The primary reason many cities were able to develop between the Tigris and Euphrates rivers is that the rivers were used for irrigation, which led to a food surplus. The Tigris and Euphrates rivers created a fertile land known as Mesopotamia, which allowed for the agricultural productivity necessary to support large populations and the development of urban centers. This region's rich soil, made fertile by the annual flooding of the rivers, facilitated the growth of crops, which was essential for sustaining cities and their inhabitants.
