Timarchus

Timarchus or Timarch was a usurper in the Seleucid empire between 163–160 BC.

A Greek nobleman, possibly from Miletus in Asia Minor, Timarchus was a friend of the Seleucid prince Antiochus IV Epiphanes during his time as a hostage to the Roman Republic. He was appointed satrap of Media in western Iran when Antiochus IV Epiphanes became king in 175 BC, and his brother Heracleides became minister of the royal finances. The Persian part of the empire was threatened by the Parthian kingdom, and Timarchus probably spent much of his time reinforcing the defences. The Seleucid realms probably extended as far as the area of Teheran during this time.

Short reign and defeat

In the turmoil following the death of Antiochus IV during a Persian campaign in 163 BC, Timarchus became the more or less independent ruler of Media, opposing the general Lysias who acted as steward for the infant king Antiochus V Eupator, son of Antiochus IV.

In 162 BC Demetrius I, the proper heir to the Seleucid throne, became king, killing Lysias as well as the young Antiochus V. This may well have been the provocation that caused Timarchus to take the final step to independence and declare himself king.
