Antiochus XI Epiphanes or Philadelphus, ruler of the Greek Seleucid kingdom, was a son of Antiochus VIII Grypus and brother of Seleucus VI Epiphanes. He was a minor participant in the civil wars which clouded the last years of the once glorious Seleucids, now reduced to local dynasties in Syria. Following the defeat of his brother in 95 BC by Antiochus X Eusebes, Antiochus XI and yet another brother, Philip I Philadelphus, opted for revenge and besieged Antiochia. After the campaign had ended in defeat, Antiochus was forced to flee but drowned in the river Orontes while trying to cross it on horseback. The year was 92 BC.

Antiochus XIII Dionysus Philopator Kallinikos, known as Asiaticus was one of the last rulers of the Greek Seleucid kingdom.

He was son of king Antiochus X Eusebes and the Ptolemaic princess Cleopatra Selene, who acted as regent for the boy after his father's death sometime between 92 and 85 BC. Some time after Tigranes had conquered Syria (83 BC), she travelled to Rome to have her sons recognized as kings of Egypt, but to no avail. They were there between at least between 75 BC and 73 BC; recognized as "Kings of Syria", and "maintained a royal state" (Bevan, p. 263). Selene was eventually captured and killed by Tigranes, but after the latter's defeat by Pompey, the residents of Antioch hailed Antiochus XIII as king, and Lucius Lucullus approved his appointment as client ruler of Syria (69 BC).

In 64 BC, Pompey had him deposed and killed by an Arab chieftain Sampsiceramus (Shemashgeram). Antiochus' death is traditionally said to have ended the Seleucid dynasty, but he was survived by Philip II Philoromaeus for a short time.

Antiochus XII Dionysos (Epiphanes/Philopator/Callinicus), a ruler of the Greek Seleucid kingdom who reigned 87–84 BC, was the fifth son of Antiochus VIII Grypus to take up the diadem. He succeeded his brother Demetrius III Eucaerus as separatist ruler of the southern parts of the last remaining Seleucid realms, basically Damascus and its surroundings.

Antiochus initially gained support from Ptolemaic forces and was the last Seleucid ruler of any military reputation, even if it was on a local scale. He made several raids into the territories of the Jewish Hasmonean kings, and tried to check the rise of the Nabataean Arabs. A battle against the latter turned out to be initially successful, until the young king was caught in a melee and killed by an Arab soldier. Upon his death the Syrian army fled and mostly perished in the desert. Soon after, the Nabateans conquered Damascus.

Antiochus' titles - apart from Dionysos - mean respectively (God) Manifest, Father-loving and Beautiful Victor. The last Seleucid kings often used several epithets on their coins.
