The Nabataeans, also Nabateans (;  , compare to , ), were an Arabic people who inhabited northern Arabia and the Southern Levant, and whose settlements, most prominently the assumed capital city of Petra, in AD 37 – c. 100, gave the name of Nabatene to the borderland between Arabia and Syria, from the Euphrates to the Red Sea. Their loosely controlled trading network, which centered on strings of oases that they controlled, where agriculture was intensively practiced in limited areas, and on the routes that linked them, had no securely defined boundaries in the surrounding desert. Trajan conquered the Nabataean kingdom, annexing it to the Roman Empire, where their individual culture, easily identified by their characteristic finely potted painted ceramics, became dispersed in the general Greco-Roman culture and was eventually lost. They were later converted to Christianity. Jane Taylor, a writer, describes them as "one of the most gifted peoples of the ancient world".
