The Decapolis (Greek: Δεκάπολις, Ten Cities) was a group of ten cities on the eastern frontier of the Roman Empire in the southeastern Levant. The cities were grouped together because of their language, culture, location, and political status, with each functioning as an autonomous city-state. Though sometimes described as a "league" of cities, it is now believed that they were never formally organized as a political unit. The Decapolis was a center of Greek and Roman culture in a region that was otherwise ancient Semitic-speaking peoples (Nabataeans, Arameans, and Judeans). In the time of the Emperor Trajan, the cities were placed into the provinces of Syria and Arabia Petraea; after a later reorganization several cities were placed in Syria Palaestina and later Palaestina Secunda.
