Answer
Alexander II Zabinas's reign as King of Syria lasted from 128-123 BCE. He seized the throne from Demetrius II Nicator with the aid of the Seleucid pretender, Antiochus Grypos, and his mother Cleopatra Thea. However, he later became embroiled in conflicts with both Grypos and Demetrius II, leading to his eventual defeat and death in 123 BCE.
