The father of Sampsiceramus I, Aziz also known as Azizus the Arab[15] and Azizus the Phylarch of the Arabs[15] was an ally to the last Seleucid Greek Monarchs of Syria. Aziz is associated with the rule of the Seleucid Kings Philip I Philadelphus and his brother Demetrius III Eucaerus.[15] Aziz may had assisted Philip I some years before about 87 BC, in the defeat of Demetrius III who ended his days in Parthian exile.[15] Aziz assisted in putting the last Seleucid King Philip II Philoromaeus, the son of Philip I on the throne, by arranging to meet him and putting the Diadem on his head.[15] However Philip II realised that Aziz befriended him to murder him to gain a portion of a divided Syrian Kingdom, realised the plot and fled to Antioch.[15]
