 After Alexander the Great's death in 323 BC, his empire split among his generals.During the conflict between Alexander's generals, Antigonus I conquered the Levant, and this brought him to the borders of Edom, just north of Petra.According to Diodorus Siculus, Antigonus sought to add ""the land of the Arabs who are called Nabataeans"" to his existing territories of Syria and Phoenicia.
