Philip II Philoromaeus in Wikipedia
Philip II Philorhomaeus ("Friend of the Romans") or Barypous ("heavy-foot"), a ruler of the Hellenistic Seleucid kingdom, was the son of the Seleucid king Philip I Philadelphus.
Philip II himself briefly reigned parts of Syria in the 60s BC, as a client king under Pompey. He competed with his second cousin Antiochus XIII Asiaticus for the favours of the great Roman general, but Pompey would have none of them and had Antiochus murdered. The deposed Philip may have survived; a Seleucid prince Philip is mentioned as a prospective bridegroom to queen Berenice IV of Egypt, sister of Cleopatra VII in 56 BC. The union was however checked by the Roman governor of Syria Aulus Gabinius who probably had Philip II killed.
Philip himself was indeed an insignificant pawn, but with him ended eleven generations of Seleucid kings, arguably some of the most influential rulers of the Hellenistic world.
