Maccabean Revolt
Seleucid control over the area of Judea began diminishing with the eruption of the Maccabean Revolt in 165 BC. With Seleucid troops being involved in warfare on the Parthian front, Judea succeeded in securing its independence by 140 BC. Despite attempts of Seleucid rulers to regain territories, the conquests of Pompey in 64 BC were a decisive blow to them, and Syria became part of the Roman Republic.
