Antiochus XIII Philadelphus, known as Asiaticus, (Ἀσιατικός) was the penultimate ruler of the Seleucid kingdom.

Antiochus X Eusebes Philopator was a Seleucid monarch who reigned as King of Syria during the Hellenistic period between 95 BC and 92 BC or 89/88 BC. He was the son of Antiochus IX and perhaps his Egyptian wife Cleopatra IV. Eusebes lived during a period of general disintegration in Seleucid Syria, characterized by civil wars, foreign interference by Ptolemaic Egypt and incursions by the Parthians. Antiochus IX was killed in 95 BC at the hands of Seleucus VI, the son of his half-brother and rival Antiochus VIII. Antiochus X then went to the city of Aradus where he declared himself king. He avenged his father by defeating Seleucus VI, who was eventually killed.
