In the first century o the Christian era this insignificant ceety (then Gerasa) experienced a fast ascent unner Roman rule an the Pax Romana. It became pairt o the Decapolis an grew increasingly competitive wi the aulder Petra as a commercial toun. The inhabitants wan ore in the nearbi Ajlun muntains. Stairtin in the middle o the 1st century, this upswing led tae active biggin an a rich abundance o airchitectural monuments, still impressive today. In the 2nt century, the Roman expansion wars in Asie led tae further gains. Well-made roads wur built tae Pella, Philadelphia (nou Amman), Dion an tae the provincial caipital Bos(t)ra. Emperor Hadrian visitit the ceety in the winter o 129-130. In the follaein centuries the poleetical situation in this region chynged fundamentally an the ceety's means declined. Durin this time an aa Christianity wis on the ascendant an mony kirks wur built. Gerasa haed its awn bishop—still the day it is a Titularbistum—an bishop Placcus (or Plancus) participatit in the Cooncil o Chalcedon. Nicomachus of Gerasa came from this Gerasa.
