The region of present Jordan will prosper…
108 CE
The region of present Jordan will prosper under Roman rule, and many new towns and villages will be established.
The entire region of modern southern Jordan and northwestern Saudi Arabia, except the twelve cities known collectively as the Decapolis, is after 107 made part of the new province called Arabia Petraea.
Trajan declares Bostra to be the capital of the province, but he also awards Petra the status of metropolis.
With Roman conquest comes the imposition of Greek in official discourse.
This is standard for a province in Eastern Rome, but Arabia has far less of the history of Hellenization than its neighbors, and the language had been little used before its introduction by the Romans.
Post-conquest Arabia nevertheless adopts Greek popularly, as well as officially, practically supplanting Nabataean and Aramaic, as evidenced by inscriptions at Umm al Quttain.
