Philip I Philadelphus

Philip I Philadelphus (Greek: Φίλιππος Α' ὁ Φιλάδελφος, "Philip the brother-loving"), a ruler of the Hellenistic Seleucid kingdom, was the fourth son of Antiochus VIII Grypus and his wife Tryphaena. Philip I took the diadem in 95 BC together with his brother (probably twin) Antiochus XI Ephiphanes, after the eldest son Seleucus VI Epiphanes was killed by their cousin Antiochus X Eusebes. He established himself in Antiochia after 92 BC and survived attacks from younger brother Demetrius III Eucaerus. His rule was ended in 83 BC when Tigranes conquered Syria, or earlier. He disappears from history at that point, but coins bearing his portrait were issued by later Roman authorities.
