Ur (cuneiform 𒋀𒀕𒆠, 𒋀𒀊𒆠, Sumerian Urim, Akkadian Uru) — one of the oldest Sumerian city-states of ancient southern Mesopotamia, existed from the 6th millennium BC to the 4th century BC. Ur was located in southern Babylonia, to the south of modern Tell El-Muqayyar in Iraq, near Nasiriyah, in the lowlands on the western bank of the Euphrates River in an area that has the modern Arabic name "Tell El-Muqayyar" ("Bitumen Hill"). The city is mentioned in the Old Testament as "Ur of the Chaldeans," the birthplace of Abraham.
