Decapolis

The Decapolis ("Ten Cities"; Greek: deka, ten; polis, city) was a group of ten cities on the eastern frontier of the Roman Empire in Judea and Syria. The ten cities were not an official league or political unit, but they were grouped together because of their language, culture, location, and political status, with each possessing a certain degree of autonomy and self-rule. The Decapolis cities were centers of Greek and Roman culture in a region that was otherwise Semitic (Nabatean, Aramean, and Jewish). With the exception of Damascus, Hippos and Scythopolis, the "Region of the Decapolis" was located in modern-day Jordan.
