However, Seleucus IV is assassinated by his chief minister [[Heliodorus (minister)|Heliodorus]] who then seizes the Syrian throne.
* Antiochus manages to oust Heliodorus and takes advantage of Demetrius' captivity in Rome to seize the throne for himself under the name [[Antiochus IV Epiphanes]].
* During this period of uncertainty in Syria, the Egyptian ruler, Ptolemy VI, lays claim to [[Coele Syria]], [[Palestine (region)|Palestine]], and [[Phoenicia]], which the Seleucid king [[Antiochus III the Great|Antiochus III]] has previously conquered.

* [[Timarchus]] is appointed governor of [[Medes|Media]] in western [[Iran|Persia]] by Antiochus IV to deal with the growing threat from the [[Parthia]]ns while Timarchus' brother, Heracleides, becomes minister of the royal finances.
