Antiochus IV Epiphanes was a Greek Hellenistic king who ruled the Seleucid Empire from 175 BC until his death in 164 BC. He was a son of King Antiochus III the Great. Originally named Mithradates, he assumed the name Antiochus after he ascended the throne. Notable events during Antiochus's reign include his near-conquest of Ptolemaic Egypt, his persecution of the Jews of Judea and Samaria, and the rebellion of the Jewish Maccabees.

Antiochus III the Great was a Greek Hellenistic king and the 6th ruler of the Seleucid Empire, reigning from 223 to 187 BC. He ruled over the region of Syria and large parts of the rest of western Asia towards the end of the 3rd century BC. Rising to the throne at the age of eighteen in April/June 223 BC, his early campaigns against the Ptolemaic Kingdom were unsuccessful, but in the following years Antiochus gained several military victories and substantially expanded the empire's territory. His traditional designation, the Great, reflects an epithet he assumed. He also assumed the title Basileus Megas, the traditional title of the Persian kings. A militarily active ruler, Antiochus restored much of the territory of the Seleucid Empire, before suffering a serious setback, towards the end of his reign, in his war against Rome.
