Seleucid Kingdom Philip I AR Tetradrachm CH AU

Philip I Epiphanes Philadelphus (Ancient Greek: Φίλιππος Ἐπιφανής Φιλάδελφος; between 124 and 109 BC–83 or 75 BC) was a Hellenistic Seleucid monarch who reigned as the king of Syria from 94 to either 83 or 75 BC. The son of Antiochus VIII and his wife Tryphaena, he spent his early life in a period of civil war between his father and his uncle Antiochus IX. The conflict ended with the assassination of Antiochus VIII; Antiochus IX took power in the Syrian capital Antioch, but soon fell in battle with Antiochus VIII's eldest son Seleucus VI.

After the murder of Seleucus VI in 94 BC, Philip I became king with his twin brother Antiochus XI, and planned to avenge Seleucus VI. In 93 BC Antiochus XI took Antioch from Antiochus IX's son Antiochus X. Antiochus XI became the senior king, and Philip I remained in a base in Cilicia. Antiochus X returned and killed Antiochus XI that year. Philip I then allied with his younger brother Demetrius III, who was based in Damascus. Antiochus X was probably killed in 88 BC. Demetrius III took the capital and besieged Philip I in Beroea (Aleppo), but the latter prevailed and took Antioch; their youngest brother Antiochus XII took Damascus.
