Mari (modern Tell Hariri), was an ancient Semitic city in Syria. Its remains constitute a tell located 11 kilometers north-west of Abu Kamal on the Euphrates river western bank, some 120 kilometers southeast of Deir ez-Zor. It flourished as a trade center and hegemonic state between 2900 BC and 1759 BC. As a purposely built city, the existence of Mari was related to its position in the middle of the Euphrates trade routes; this position made it an intermediary between Sumer in the south and the Levant in the west.
