Between the 3rd century BCE and the 7th century CE, Hippos was the site of a Greco-Roman city,[2] which declined under Muslim rule and was abandoned after an earthquake in 749. Besides the fortified city itself, Hippos controlled two port facilities on the lake and an area of the surrounding countryside. Hippos was part of the Decapolis, or Ten Cities, a region in Roman Jordan, Syria and Israel that were culturally tied more closely to Greece and Rome than to the Semitic ethnoi around.
