History
Simon took a prominent part in the Maccabean Revolt against the Seleucid Empire led by his brothers, Judas Maccabaeus and Jonathan Apphus. The successes of the Jews rendered it expedient for the Seleucid leaders in Syria to show them special favour. Therefore, Antiochus VI appointed Simon strategos, or military commander, of the coastal region stretching from the Ladder of Tyre to Egypt. As strategos, Simon gained control of the cities of Beth-zur and Joppa, garrisoning them with Jewish troops, and built the fortress of Adida.
After the capture of Jonathan by the Seleucid general Diodotus Tryphon, Simon was elected leader by the people, assembled at Jerusalem. He at once completed the fortification of the capital, and made Joppa secure.
At Hadid he blocked the advance of Tryphon, who was attempting to enter the country and seize the throne of Syria. Realizing he could gain nothing by force, Tryphon demanded a ransom for Jonathan and for the release of Jonathan's sons as hostages. Although Simon was aware that Tryphon would deceive him, both Josephus and 1 Maccabees state that he acceded to both demands so that the people might see that he had done everything possible for his brother. Jonathan was nevertheless assassinated, and the hostages were not returned. Simon thus became the sole leader of the people. This when Simon Thassi became High Priest of Judaea and Ethnarch (Prince of Judaea).
Legacy Simon (and its Hebrew form, Simeon) would go on to become the most popular male name for some three centuries afterward in both the Hasmonean Kingdom and Roman Judaea. This was both to honor a Jewish hero who had attained independence for the Jewish state, as well as because "Simon" did not sound artificial or strange to Greek ears.
