A short time later, Seleucus was killed and his brother Antiochus IV began to reign over Syria (in 3586 - 174 B.C.E.). He was a tyrant of a rash and impetuous nature, contemptuous of religion and of the feelings of others. He was called "Epiphanes," meaning "the gods’ beloved." Several of the Syrian rulers received similar titles. But a historian of his time, Polebius, gave him the epithet Epimanes ("madman"), a title more suitable to the character of this harsh and cruel king.
Desiring to unify his kingdom through the medium of a common religion and culture, Antiochus tried to root out the individualism of the Jews by suppressing all the Jewish Laws. He removed the righteous High Priest, Yochanan, from the Temple in Jerusalem, and in his place installed Yochanan’s brother Joshua, who loved to call himself by the Greek name of Jason. For he was a member of the Hellenist party, and he used his high office to spread more and more of the Greek customs among the priesthood.
Joshua or Jason was later replaced by another man, Menelaus, who had promised the king that he would bring in more money than Jason did. When Yochanan, the former High Priest, protested against the spread of the Hellenists’ influence in the Holy Temple, the ruling High Priest hired murderers to assassinate him.
Antiochus was at that time engaged in a successful war against Egypt. But messengers from Rome arrived and commanded him to stop the war, and he had to yield. Meanwhile, in Jerusalem, a rumor spread that a serious accident had befallen Antiochus. Thinking that he was dead, the people rebelled against Menelaus. The treacherous High Priest fled together with his friends.
