Antiochus IX Eusebes Cyzicenus (Greek : Ἀντίοχος Εὐσεβής Κυζικηνός, "Antiochus the Pious, the Cyzicene") was a ruler of the Hellenistic Seleucid kingdom. He was the son of Antiochus VII Sidetes and Cleopatra Thea. [2] He left the kingdom in 129 BC and went to the city of Cyzicus, but he returned in 116 BC to challenge his half-brother Antiochus VIII for power.


The siblings fought a twenty-year civil war. In 112 BC, Antiochus IX's wife, Cleopatra IV, was killed by her sister Tryphaena, the wife of Antiochus VIII. Tryphaena herself died shortly afterwards. Antiochus VIII was assassinated in 96 BC; he was succeeded by his sons Seleucus VI and Demetrius III. Antiochus IX then took the capital Antioch and married his deceased wife's sister Cleopatra Selene, who was herself the widow of Antiochus VIII. Seleucus VI continued the war against his uncle. Antiochus IX Eusebes Cyzicenus was killed in battle in 96 BC.

The son of Antiochus VII Sidetes and Cleopatra Thea, [2] upon the death of his father in Parthia and his uncle Demetrius II Nicator's return to power (129 BC), his mother sent him to Cyzicus on the Bosporus, thus giving him his nickname.[ citation needed ]

Following the death of his mother c. 121 BC, [2] Antiochus IX Cyzicenus challenged his half-brother, Antiochus VIII Grypus, for power over Syria. [2]

He returned to Syria in 116 BC to claim the Seleucid throne from his half-brother/cousin Antiochus VIII Grypus, with whom he eventually divided Syria,[ citation needed ] that same year. [2]

Antiochus IX Cyzicenus was first married to Cleopatra IV, who was said to have been killed in 112 BC[ citation needed ] by her sister and rival Tryphaena, wife of King Grypus. [4] [5] [6] After the death of Grypus and Antiochus' capture of the capital, Antiochus married Cleopatra Selene of Syria, the sister of his former wife, Cleopatra IV.[ citation needed ]

He was subsequently killed in battle by the son of Grypus, Seleucus VI Epiphanes, later in 96 BC.


Antiochus IX probably created the Iturean tetrarchy as an ally against Antiochus VIII. [7] Beginning his reign in 95 BC, Antiochus X Eusebes' first achievement was to defeat his double half-cousin/second cousin Seleucus VI Epiphanes, thus avenging the recent death of his father, Antiochus IX Cyzicenus. The epithets he took tell much of his story: Eusebes (being a title of his father) and also Philopator (father-loving) both honoured his father. After that, he ruled Antioch and its surroundings, fighting endlessly against the four brothers of Seleucus VI, the Nabataeans and the Parthian Empire.[ citation needed ]

The conflict ended with the assassination of Antiochus VIII, followed by the establishment of Antiochus IX in Antioch, the capital of Syria. Antiochus VIII's eldest son Seleucus VI, in control of western Cilicia, marched against his uncle and had him killed, taking Antioch for himself, only to be expelled from it and driven to his death in 94 BC by Antiochus IX's son Antiochus X.

Seleucus VI Epiphanes Nicator was a Hellenistic Seleucid monarch who ruled Syria between 96 and 94 BC. He was the son of Antiochus VIII and his Egyptian wife Tryphaena.

In 95 BC, Antiochus IX marched against his nephew, but lost the battle and was killed.

Antiochus VIII Epiphanes/Callinicus/Philometor, nicknamed Grypus, was the ruler of the Syrian Seleucid Empire from 125 to 96 BC. He was the younger son of Demetrius II and Cleopatra Thea. He may have spent his early life in Athens and returned to Syria after the deaths of his father and brother Seleucus V. At first he was joint ruler with his mother. Fearing her influence, Antiochus VIII had Cleopatra Thea poisoned in 121 BC.

The Seleucid king Seleucus V Philometor, ruler of the Hellenistic Seleucid kingdom, was the eldest son of Demetrius II Nicator and Cleopatra Thea. The epithet Philometor means "mother-loving" and in the Hellenistic world usually indicated that the mother acted as co-regent for the prince.

He was a son of Ptolemy VIII Physcon and Cleopatra III, and younger brother of Ptolemy IX. His birth name was probably Alexander.

Cleopatra IV was Queen of Egypt briefly from 116 to 115 BC, jointly with her husband Ptolemy IX Lathyros. She later became queen consort of Syria as the wife of Antiochus IX Cyzicenus.

Cleopatra Selene of Syria Monarch of Syria

Cleopatra II Selene was the monarch of Syria from 82 to 69 BC. The daughter of Ptolemy VIII and Cleopatra III of Egypt, Cleopatra Selene was favoured by her mother and became a pawn in Cleopatra III's political manoeuvres. In 115 BC, Cleopatra III forced her son Ptolemy IX to divorce his sister-wife Cleopatra IV, and chose Cleopatra Selene as the new queen consort of Egypt. Tension between the king and his mother grew and ended with his expulsion from Egypt, leaving Cleopatra Selene behind; she probably then married the new king, her other brother Ptolemy X.
