Sometime later, maybe between invasions of Greece, Ahasuerus appointed Haman the Agagite as his second in command. Of course, everyone bowed and groveled to him–that is everyone except Mordecai, who claimed it was against his Jewish principles. This pissed Haman off and he decided he would punish all of the Jews for Mordecai’s insult. So he told King Ahasuerus about this scattered and upstart people who refused to follow the king’s laws, and he offered the king 75,000 pounds of silver if the king would allow him to issue a royal edict that on a certain day in the near future, it would be open season on Jews throughout the empire.
The king took the money and issued the edict–which of course caused confusion and outrage.
