Antiochus IV Epiphanes
Antiochus’s father Antiochus the Great ruled the Seleucid Empire and fought wars against the Roman Republic. After ending them with a treaty, the Romans took the younger Antiochus hostage to make sure that his father didn’t disturb the peace, since that was one of the rules in the treaty. After Antiochus’s father died, his older brother Seleucus IV Philopator became king so the Romans freed Antiochus and took Seleucus’s son. Someone named Heliodorus worked for the government of the Seleucid Empire so Heliodorus (minister) killed Seleucus to take over the Empire. Then Antiochus teamed up with King Eumenes II to take over and become the new king and Antiochus (probably) killed his nephew so that he could stay king.
