164 BC

By place

Egypt

• The Egyptian King Ptolemy VI Philometor is expelled from Alexandria by his brother Ptolemy VIII Euergetes and flees to Rome to seek support.

Seleucid Empire

• The Seleucid king Antiochus IV Epiphanes died while on a campaign in Tabae in Persia. He is succeeded by his son Antiochus V Eupator who is only nine years old. The regent for the boy is the late king's chancellor, Lysias, who was left in charge of Syria when Antiochus IV departed for his campaign in Persia. Lysias is, however, seriously challenged by other Syrian generals and finds himself with a precarious hold on power. To make matters worse for him, the Roman Senate is holding Demetrius, the son of the former king Seleucus IV and, therefore, the rightful heir to the Seleucid throne, as a hostage. By threatening to release him, the Senate can influence events in the Seleucid kingdom.
• The Battle of Beth Zur was fought between Jewish rebel forces led by Judas Maccabeus and a Seleucid army led by the regent Lysias. Judas Maccabeus wins the battle and is able to recapture Jerusalem soon after. Judas purifies the defiled Temple in Jerusalem, destroys the idols erected there by Antiochus IV and restores the service in the Temple. The reconsecration of the Temple becomes an annual feast of dedication in the Jewish calendar, Hanukkah.

Roman Republic

• Rhodes signs a treaty with Rome and becomes its ally.
• Lucius Aemilius Paullus Macedonicus is elected censor in Rome.
