It consisted of the former Nabataean Kingdom in the southern Levant, the Sinai Peninsula, and the northwestern Arabian Peninsula. Its capital was Petra. It was bordered on the north by Syria, on the west by Judaea and Egypt, and on the south and east by the rest of Arabia, known as Arabia Deserta and Arabia Felix.
