Ur

Ur was an ancient city in southern Mesopotamia, located near the mouth (at the time) of the Euphrates and Tigris rivers on the Persian Gulf and close to Eridu. It is considered to be one of the earliest known civilizations in world history. Because of marine regression, the remains are now well inland in present-day Iraq, south of the Euphrates on its right bank, and named Tell el-Mukayyar ^[1], near the city of Nasiriyah south of Baghdad.
