Mari (modern Tell Hariri, Syria) was an ancient Sumerian and Amorite city, located 11 kilometers north-west of the modern town of Abu Kamal on the western bank of the Euphrates river, some 120 km southeast of Deir ez-Zor, Syria. It is thought to have been inhabited since the 5th millennium BC, although it flourished with a series of superimposed palaces that spanned a thousand years, from 2900 BC until 1759 BC, when it was sacked by Hammurabi.
